Cursor IDE support hallucinates lockout policy, causes user cancellations

1 year ago (old.reddit.com)

Earlier today Cursor, the magical AI-powered IDE started kicking users off when they logged in from multiple machines.

Like,you’d be working on your desktop, switch to your laptop, and all of a sudden you're forcibly logged out. No warning, no notification, just gone.

Naturally, people thought this was a new policy.

So they asked support.

And here’s where it gets batshit: Cursor has a support email, so users emailed them to find out. The support peson told everyone this was “expected behavior” under their new login policy.

One problem. There was no support team, it was an AI designed to 'mimic human responses'

That answer, totally made up by the bot, spread like wildfire.

Users assumed it was real (because why wouldn’t they? It's their own support system lol), and within hours the community was in revolt. Dozens of users publicly canceled their subscriptions, myself included. Multi-device workflows are table stakes for devs, and if you're going to pull something that disruptive, you'd at least expect a changelog entry or smth.

Nope.

And just as people started comparing notes and figuring out that the story didn’t quite add up… the main Reddit thread got locked. Then deleted. Like, no public resolution, no real response, just silence.

To be clear: this wasn’t an actual policy change, just a backend session bug, and a hallucinated excuse from a support bot that somehow did more damage than the bug itself.

But at that point, it didn’t matter. People were already gone.

Honestly one of the most surreal product screwups I’ve seen in a while. Not because they made a mistake, but because the AI support system invented a lie, and nobody caught it until the userbase imploded.

There is a certain amount of irony that people try really hard to say that hallucinations are not a big problem anymore and then a company that would benefit from that narrative gets directly hurt by it.

Which of course they are going to try to brush it all away. Better than admitting that this problem very much still exists and isn’t going away anytime soon.

    The section about hallucinations is deeply relevant.

    Namely, Claude sometimes provides a plausible but incorrect chain-of-thought reasoning when its “true” computational path isn’t available. The model genuinely believes it’s giving a correct reasoning chain, but the interpretability microscope reveals it is constructing symbolic arguments backward from a conclusion.

    https://en.wikipedia.org/wiki/On_Bullshit

    This empirically confirms the “theory of bullshit” as a category distinct from lying. It suggests that “truth” emerges secondarily to symbolic coherence and plausibility.

    This means knowledge itself is fundamentally symbolic-social, not merely correspondence to external fact.

    Knowledge emerges from symbolic coherence, linguistic agreement, and social plausibility rather than purely from logical coherence or factual correctness.

    • While some of what you say is an interesting thought experiment, I think the second half of this argument has, as you'd put it, a low symbolic coherence and low plausibility.

      Recognizing the relevance of coherence and plausibility does not need to imply that other aspects are any less relevant. Redefining truth merely because coherence is important and sometimes misinterpreted is not at all reasonable.

      Logically, a falsehood can validly be derived from assumptions when those assumptions are false. That simple reasoning step alone is sufficient to explain how a coherent-looking reasoning chain can result in incorrect conclusions. Also, there are other ways a coherent-looking reasoning chain can fail. What you're saying is just not a convincing argument that we need to redefine what truth is.

      This just seems like a redefinition of the word "knowledge" different from how it's commonly used. When most people say "knowledge" they mean beliefs that are also factually correct.

      Sounds very human. It's quite common that we make a decision based on intuition, and the reasons we give are just post-hoc justification (for ourselves and others).

    • I haven’t used Cursor yet. Some colleagues have and seemed happy. I’ve had GitHub Copilot on for what feels like a couple years, a few days ago VS Code was extended to provide an agentic workflow, MCP, bring-your-own-key, it interprets instructions in a codebase. But the UX and the outputs are bad in over 3/4 of cases. It’s a nuisance to me. It injects bad code even though it has the full context. Is Cursor genuinely any better?

      To me it feels like people that benefit from or at least enjoy that sort of assistance and I solve vastly different problems and code very differently.

      I’ve done exhausting code reviews on juniors’ and middles’ PRs but what I’ve been feeling lately is that I’m reviewing changes introduced by a very naive poster. It doesn’t even type-check. Regardless of whether it’s Claude 3.7, o1, o3-mini, or a few models from Hugging Face.

      I don’t understand how people find that useful. Yesterday I literally wasted half an hour for a test suite setup a colleague of mine introduced to the codebase that wasn’t good, and I tried delegating that fix to several of the Copilot models. All of them missed the point, some even introduced security vulnerabilities in the process invalidating JWT validation, I tried “vide coding” it till it works, until I gave up in frustration and just used an ordinary search engine, which led me to the docs, in which I immediately found the right knob. I reverted all that crap and did the simple and correct thing. So my conclusion was simple: vibe coding and LLMs made the codebase unnecessarily more complicated and wasted my time. How on earth do people code whole apps with that?

      > # ChatGPT is bullshit

      > Recently, there has been considerable interest in large language models: machine learning systems which produce human-like text and dialogue. Applications of these systems have been plagued by persistent inaccuracies in their output; these are often called “AI hallucinations”. We argue that these falsehoods, and the overall activity of large language models, is better understood as bullshit in the sense explored by Frankfurt (On Bullshit, Princeton, 2005): the models are in an important way indifferent to the truth of their outputs. We distinguish two ways in which the models can be said to be bullshitters, and argue that they clearly meet at least one of these definitions. We further argue that describing AI misrepresentations as bullshit is both a more useful and more accurate way of predicting and discussing the behaviour of these systems.

    • Offtopic but I'm still sad that "On Bullshit" didn't go for that highest form of book titles, the single noun like "Capital", "Sapiens", etc

  • It's a huge problem. I just can't get past it and I get burned by it every time I try one of these products. Cursor in particular was one of the worst; the very first time I allowed it to look at my codebase, it hallucinated a missing brace (my code parsed fine), "helpfully" inserted it, and then proceeded to break everything. How am I supposed to trust and work with such a tool? To me, it seems like the equivalent of lobbing a live hand grenade into your codebase.

    Don't get me wrong, I use AI every day, but it's mostly as a localized code complete or to help me debug tricky issues. Meaning I've written and understand the code myself, and the AI is there to augment my abilities. AI works great if it's used as a deductive tool.

    Where it runs into issues is when it's used inductively, to create things that aren't there. When it does this, I feel the hallucinations can be off the charts -- inventing APIs, function names, entire libraries, and even entire programming languages on occasion. The AI is more than happy to deliver any kind of information you want, no matter how wrong it is.

    AI is not a tool, it's a tiny Kafkaesque bureaucracy inside of your codebase. Does it work today? Yes! Why does it work? Who can say! Will it work tomorrow? Fingers crossed!

    • You're not supposed to trust the tool, you're supposed to review and rework the code before submitting for external review.

      I use AI for rather complex tasks. It's impressive. It can make a bunch of non-trivial changes to several files, and have the code compile without warnings. But I need to iterate a few times so that the code looks like what I want.

      That being said, I also lose time pretty regularly. There's a learning curve, and the tool would be much more useful if it was faster. It takes a few minutes to make changes, and there may be several iterations.

      69 replies →

    • I'd add that the deductive abilities translate to well-defined spec. I've found it does well when I know what APIs I want it to use, and what general algorithmic approaches I want (which are still sometimes brainstormed separately with an AI, but not within the codebase). I provide it a numbered outline of the desired requirements and approach to take, and it usually does a good job.

      It does poorly without heavy instruction, though, especially with anything more than toy projects.

      Still a valuable tool, but far from the dreamy autonomous geniuses that they often get described as.

    • > the very first time I allowed it to look at my codebase, it hallucinated a missing brace (my code parsed fine), "helpfully" inserted it, and then proceeded to break everything.

      This is not an inherent flaw of LLMs, rather it is a flaw of a particular implementation-if you use guided sampling, so during sampling you only consider tokens allowed by the programming language grammar at that position, it becomes impossible for the LLM to generate ungrammatical output

      > When it does this, I feel the hallucinations can be off the charts -- inventing APIs, function names, entire libraries,

      They can use guided sampling for this too - if you know the set of function names which exist in the codebase and its dependencies, you can reject tokens that correspond to non-existent function names during sampling

      Another approach, instead of or as well as guided sampling, is to use an agent with function calling - so the LLM can try compiling the modified code itself, and then attempt to recover from any errors which occur.

    • > it hallucinated a missing brace (my code parsed fine), "helpfully" inserted it, and then proceeded to break everything.

      Your tone is rather hyperbolic here, making it sound like an extra brace resulted in a disaster. It didn't. It was easy to detect and easy to fix. Not a big deal.

    • You say slowly, but in my opinion Apple made an out of character misstep by releasing a terrible UX to everyone. Apple intelligence is a running joke now.

      Apple fumbled a bit with Siri, and I'm guessing they're not too keen to keep chasing everyone else, since outside of limited applications it turns out half baked at best.

      Sadly, unless something shinier comes along soon, we're going to have to accept that everything everywhere else is just going to be awful. Hallucinations in your doctor's notes, legal rulings, in your coffee and laundry and everything else that hasn't yet been IoT-ified.

    • When you got 1-2billion users a day doing maybe 10 billion prompts a day, it’s risky

  • Did anyone say that? They are an issue everywhere, including for code. But with code at least I can have tooling to automatically check and feed back that it hallucinated libraries, functions etc, but with just normal research / problems there is no such thing and you will spend a lot of time verifying everything.

    • I use Scala which has arguably the best compiler/type system with Cursor.

      There is no world in which a compiler or tooling will save you from the absolute mayhem it can do. I’ve had it routinely try to re-implement third party libraries, modify code unrelated to what it was asked, quietly override functions etc.

      It’s like a developer who is on LSD.

    • Yes, most people who have an incentive in pushing AI say that hallucinations aren't a problem, since humans aren't correct all the time.

    • Except when the hallucinated library exists and it's malicious. This is actually happening. Without AI, by using plain google you are less likely to fall for that (so far).

    • Until the model injects a subtle change to your logic that does type-check and then goes haywire in production. Just takes a colleague of yours under pressure and another one to review the PR, and then you’re on call and they out sick or on vacation.

  • People hallucinate all the time out of pressure or habit. We don't need AI for that. It's hard to tell most people from AI. Most people would fail Turing tests as subjects.

  • I see this fallacy often too.

    My company provides hallucination detection software: https://cleanlab.ai/tlm/

    But we somehow end up in sales meetings where the person who requested the meeting claims their AI does not hallucinate ...

(Cursor cofounder)

Apologies - something very clearly went wrong here. We’ve already begun investigating, and some very early results:

* Any AI responses used for email support are now clearly labeled as such. We use AI-assisted responses as the first filter for email support.

* We’ve made sure this user is completely refunded - least we can do for the trouble.

For context, this user’s complaint was the result of a race condition that appears on very slow internet connections. The race leads to a bunch of unneeded sessions being created which crowds out the real sessions. We’ve rolled out a fix.

Appreciate all the feedback. Will help improve the experience for future users.

    Did you remove it so people can't find about this screwup when searching Google?

    Anyway, if you acknowledge it was a mistake to remove the thread, could you please un-remove it?

    • The whole subreddit is moderated poorly. I’ve seen plenty of users post on r/LocalLlama about how something negative or constructive they said on the Cursor sub was just removed.

  • Why would anyone trust you?

    The best case scenario is that you lied about having people answer support. LLMs pretending to be people (you named it Sam!) and not labeled as such is clearly intended to be deceptive. Then you tried to control the narrative on reddit. So forgive me if I hit that big red DOUBT button.

    Even in your post you call it "AI-assisted responses" which is as weaselly as it gets. Was it a chatbot response or was a human involved?

    But 'a chatbot messed up' doesn't explain how users got locked out in the first place. EDIT: I see your comment about the race condition now. Plausible but questionable.

    So the other possible scenario is that you tried to hose your paying customers then when you saw the blowback blamed it on a bot.

    'We missed the mark' is such a trope non-apology. Write a better one.

    I had originally ended this post with "get real" but your company's entire goal is to replace the real with the simulated so I guess "you get what you had coming". Maybe let your chatbots write more crap code that your fake software engineers push to paying customers that then get ignored and/or lied to when they ask your chatbots for help. Or just lie to everyone when you see blowback. Whatever. Not my problem yet because I can write code well enough that I'm embarrassed for my entire industry whenever I see the output from tools like yours.

    This whole "AI" psyop is morally bankrupt and the world would be better off without it.

  • > Any AI responses used for email support are now clearly labeled as such.

    Because we all know how well people pay attention to such clear labels, even seasoned devs not just “end users”⁰.

    • I wish more people realized that virtually any subreddit for a company or product is run by the company - either directly or via a firm that specializes in 'sentiment analysis and management' or whatever the marketdroids call it these days. Even if they don't remove posts via moderation, they'll just hammer it with downvotes from sockpuppet accounts.

      HN goes a step further. It has a function that allows moderators to kill or boost a post by subtracting or adding a large amount to the post's score. HN is primarily a place for Y Combinator to hype their latest venture, and a "safe" place for other startups and tech companies.

    • I dunno, that seems pretty reasonable to me simply for stopping the spread of misinformation.

  • > We use AI-assisted responses as the first filter for email support.

    Literally no one wants this. The entire purpose of contacting support is to get help from a human.

    • Sorta? I mean I want my problem fixed, regardless of it it's a person or not. Having a person listen to me complain about my problems might sooth my conscience, but I can't pay my bill or why was it so high; having those answered by a system that is contextualized to my problem sand is empowered to fix it, and not just a talking to a brick wall? I wouldn't say totally fine, but at the end of the day, if my problem is solved or my query, even if it's weird, I can't say I really needed for the voice on the other end of the pHone to come from a human. If a companies business model isn't sustainable without using AI agents, it's not really my problem that it's not, but also if I'm using their product, presumably I don't want that to go away.

  • so the actual implementation of the code to log people off was also hallucination? the enforcement too? all the way to a production environment? is this safe, or just a virtual scape goat?

    • To my understanding there weren't really distinct "implementation of the code to log people off" and "enforcement" - just a bug where previous sessions were being expired when a new one was created.

      That an LLM then invented a reason when asked by users why they're being logged out isn't that surprising. While not impossible, I don't think there's currently indication that they intended to change policy and are just blaming it on a hallucination as a scape goat.

  • Thank for the details and replying here!

    Don’t let the dickish replies get to you.

  • Support emails shouldn't be AI. It's just so annoying. Put a human in the loop at least. This is a paying service, not a massive ad supported thing.

  • > * Any AI responses used for email support are now clearly labeled as such. We use AI-assisted responses as the first filter for email support.

    Don't use AI. Actually care. Like, take a step back, and realise you should give a shit about support for a paid product.

    Don't get me wrong: AI is a very effective tool, *for doing things you don't care about*. I had to do a random docker compose change the the other day. It's not production code, it will be very obvious whether or not AI output works, and I very rarely touch docker and don't care to become a super expert in it. So I prompted the change, and it was good enough and so I ran with it.

    You using AI for support tells me that you don't care about support. Which tells me whether or not I should be your customer.

    • There’s AI and there’s “AI”, and this whole drama would have been avoided by returning links to an FAQ rather found using embedding search rather than actually then trying to turn it into a textual answer, which — working with these systems all day — is madness

    • > Don't use AI. Actually care.

      I agree with this. Also, whenever I care about code, I don’t use AI. So I very rarely use AI assistants for coding.

      I guess this is why Cursor is interested in making AI assistants popular everywhere, they don’t want the association that “AI assisted” means careless. Even when it does, at least with today’s level of AI.

    • Not trying to defend them, but I think it’s a problem of scaling up. The user base grew very quickly and keeping up with the support inquiries must be a tough job. Therefore the first like of defense is AI support replies.

      I agree with you, they should care.

  • > Tinfoil hat me says that it was a policy change that they are blaming on an "AI Support Agent" and hoping nobody pokes too much behind the curtain.

    Yeah, who puts an AI in charge of support emails with no human checks and no mention that it's an AI generated reply in the response email?

  • Given how incredibly stingy tech companies are about spending any money on support, I would not be surprised if the story about it being a rogue AI support agent is 100% true.

    It also seems like a weird thing to lie about, since it's just another very public example of AI fucking up something royally, coming from a company whose whole business model is selling AI.

    • Both things can be true. The AI support bot might have been trained to respond with “yup that’s the new policy”, but the unexpected shitstorm that erupted might have caused the company to backpedal by saying “official policy? Ha ha, no of course not, that was, uh, a misbehaving bot!”

    • > how incredibly stingy tech companies are about spending any money on support

      Which is crazy. Support is part of marketing so it should get the same kind of consideration.

      Why do people think Amazon is hard to beat? Price? nope. Product range? nope. Delivery time? In part. The fact if you have a problem with your product they'll handle it? Yes. After getting burned multiple times by other retailers you're gonna pay the Amazon tax so you don't have to ask 10 times for a refund or be redirected to the supplier own support or some third party repair shop.

      Everyone knows it. But people are still stuck on the "support is a cost center" way of life so they keep on getting beat by the big bad Amazon.

  • Yeah it makes little sense to me that so many users would experience exactly the same "hallucination" from the same model. Unless it had been made deterministic but even then subtle changes in the wording would trigger different hallucinations, not an identical one.

    • What if the prompt to the “support assistant” postulates that 1) everything is a user error, 2) if it’s not, it’s a policy violation, 3) if it’s not, it may be our fuckup but we are allowed? This plus the question in the email leading to a particular answer.

      Given that LLMs are trained on lots of stuff and not just the policy of this company, it’s not hard to imagine how it could conjure that the policy (plausibly) is “one session per user”, and blame them of violating it.

  • This is the best idea I read all day. Going to implement AI for everything right now. This is a must have feature.

  • Weirdly, your conspiracy theory actually makes the turn of events less disconcerting.

    The thing is, what the AI hallucinated (if it was an AI-hallucinating), was the kind of sleezy thing companies do do. However, the thing with sleezy license changes is they only make money if the company publicizes them. Of course, that doesn't mean a company actually thinks that far ahead (X many managers really think "attack users ... profit!"). Riddles in enigmas...

LLM anything makes me queasy. Why would any self respecting software developer use this tripe? Learn how to write good software. Become an expert in the trade. AI anything will only dig a hole for software to die in. Cheapens the product, butchers the process and absolutely decimates any hope for skill development for future junior developers.

I'll just keep chugging along, with debian, python and vim, as I always have. No LLM, no LSP, heck not even autocompletion. But damn proud of every hand crafted, easy to maintain and fully understood line of code I'll write.

    Now, I don't trust the output - I review everything, and it often goes wrong. You have to know how to use it. But I would never go back.

    I'm also damn proud of my own hand-crafted code, but to avoid LLMs out of principal? That's just luddite.

      Do you double check that the LLM hasn't magically recreated someone else's copyrighted code? That's just irresponsible in certain contexts.

      > in case you feel it relevant.

      Of course it's relevant. If a 19 year old with 1 year of driving experience tries to sell me a car using their personal anecdote as a metric I'd be suspicious. If their only salient point is that "it gets me to where I'm going faster!" I'd be doubly suspicious.

  • I’m pretty much in the same boat as you, but here’s one place that LLMs helped me:

    In python I was scanning 1000’s of files each for thousands of keywords. A naive implementation took around 10 seconds, obviously the largest share of execution time after running instrumentation. A quick ChatGPT led me to Aho-Corasick and String searching algorithms, which I had never used before. Plug in a library and bam, 30x speed up for that part of the code.

    I could have asked my knowledgeable friends and coworkers, but not at 11PM on a Saturday.

    I could have searched the web and probably found it out.

    But the LLM basically auto completed the web, which I appreciate.

    • This is where education comes in. When we come cross a certain scale, we should know that O(n) comes into play, and study existing literature before trying to naively solve the problem. What would happen if the "AI" and web search didn't return anything? Would you have stuck with your implementation? What if you couldn't find a library with a usable license?

      Once I had to look up a research paper to implement a computational geometry algorithm because I couldn't find it any of the typical Web sources. There were also no library to use with a license for our commercial use.

      I'm not against use of "AI". But this increasing refusal of those who aspire to work in specialist domains like software development to systematically learn things is not great. That's just compounding on an already diminished capacity to process information skillfully.

    • Yes! This is how AI should be used. You have a question that’s quite difficult and may not score well on traditional keyword matching. An LLM can use pattern matching to point you in the right direction of well written library based on CS research and/or best practices.

    • I mean, even in the absence of knowledge of the existence of text searching algorithms (where I'm from we learn that in university) just a simple web search would have gotten you there as well no? Maybe would have taken a few minutes longer though.

    • But do you know every important detail of that library. For example, maybe that lib is not thread safe, or it allocates a lot of memory to speed thing up, or it wont work on ARM CPU because it uses some x86 hackery ASM?

    • Sounds like a job for silver/ripgrep and possibly stack exchange. Might take another minute to get it rolling but has other benefits like cost and privacy.

  • I was with you 150% (though Arch, Golang and Zed) until a friend convinced me to give it a proper go and explained more about how to talk to the LLM.

    I've had a long-term code project that I've really struggled with, for various reasons. Instead of using my normal approach, which would be to lay out what I think the code should do, and how it should work, I just explained the problem and let the LLM worry about the code.

    It got really far. I'm still impressed. Claude worked great, but ran out of free tokens or whatever, and refused to continue (fine, it was the freebie version and you get what you pay for). I picked it up again in Cursor and it got further. One of my conditions for this experiment was to never look at the code, just the output, and only talk to the LLM about what I wanted, not about how I wanted it done. This seemed to work better.

    I'm hitting different problems, now, for sure. Getting it to test everything was tricky, and I'm still not convinced it's not just fixing the test instead of the code every time there's a test failure. Peeking at the code, there are several remnants of previous architectural models littering the codebase. Whole directories of unused, uncalled, code that got left behind. I would not ship this as it is.

    But... it works, kinda. It's fast, I got a working demo of something 80% near what I wanted in 1/10 of the time it would have taken me to make that manually. And just focusing on the result meant that I didn't go down all the rabbit holes of how to structure the code or which paradigm to use.

    I'm hooked now. I want to get better at using this tool, and see the failures as my failures in prompting rather than the LLM's failure to do what I want.

    I still don't know how much work would be involved in turning the code into something I could actually ship. Maybe there's a second phase which looks more like conventional development cleaning it all up. I don't know yet. I'll keep experimenting :)

    • > never look at the code, just the output, and only talk to the LLM about what I wanted

  • I wholeheartedly agree. When the tools become actually worth using, I'll use them. Right now they suck, and they slow you down rather than speed you up. I'm hardly a world class developer and I can do far better than these things. Someone who is actually top notch will outclass them even more.

  • I understand not wanting to use LLMs that with no correctness guarantees that randomly hallucinate, but what's wrong with ordinary LSPs and autocompletion? Those seem like perfectly useful tools.

    • I had a professor who used `ed` to write his code. He said only bring able to see one line at a time forces you to think more about what you're doing.

      Anyways, Cursor generates all my code now.

  • If you are like me (same vim, python, no LLM, no autocompletion, no syntax highlighting noise), LSP will make you a better developer: it makes navigating the codebase MUCH easier, including stdlib and 3rd party dependencies.

    As a result, you don't lose flow and end up reading considerably more code than you would have otherwise.

  • Can pretty much guarantee with AI I'm a better software developer than you without. And I still love working on software used by millions of people every day, and take pride in what I do.

  • > with debian, python and vim

    Why are you cheapening the product, butchering the process and decimating any hope for further skill development by using these tools?

    Instead of python, you should be using assembly or heck, just binary. Instead of relying on an OS abstraction layer made by someone else, you should write everything from scratch on the bare metal. Don't lower yourself by using a text editor, go hex. Then your code will truly be "hand crafted". You'll have even more reason to be proud.

  • Good for you - if that’s what works for you, then keep on keeping on.

    Don’t get too hung up on what works for other people. That’s not a good look.

  • This comment presupposes that AI is only used to write code that the (presumably junior-level) author doesn’t understand.

    I’m a self-respecting software developer with 28 years of experience. I would, with some caveats, venture to say I am an expert in the trade.

    AI helps me write good code somewhere between 3x and 10x faster.

    This whole-cloth shallow dismissal of everything AI as worthless overhyped slop is just as tired and content-free as breathless claims of the limitless power or universal applicability of AI.

  • sorry for the snark, but missing the forest for the trees here. unless it's just some philosophical idea, use the tools that save you time. if anything it saves you writing boilerplate or making careless errors.

    i don't need to "hand write" every line and character in my code and guess what, it's still easy to understand and maintain because it's what would have written anyway. that or you're just bikeshedding minor syntax.

    like if you want to be proud of a "hand built" house with hammer and nails be my guest, but don't conflate the two with always being well built.

  • Why use a high level language like python? Why not assembly? Are you really proud of the slow unoptimized byte code that’s executed instead of perfectly crafting the assembly implementation optimizing for the architecture? /s

    Seriously comments like yours assume, that all the rest of us who DO make extensive use of these AI tools and have also been around the block for a while, are idiots.

  • [flagged]

    • Job market for knowledge jobs isn’t even that good anymore and plenty of people expect it to get worse regardless of their stance on AI. What makes you so sure that LLM users have a bank to laugh all the way to? Already there are many like you, the money you’d make is peanuts

    • Are you going to the bank to take out a loan? You're claiming you've outcompeted other programmers by using... optimizing compilers?

here's an archive of the original reddit post since it seemed to be instantly nuked: https://undelete.pullpush.io/r/cursor/comments/1jyy5am/psa_c...

Cursor is weird. They have a basically unused GitHub with a thousand unanswered Issues. It's so buggy in ways that VSCode isn't. I hate it. Also I use it everyday and pay for it.

That's when you know you've captured something, when people hate use your product.

Any real alternatives? I've tried continue and was unimpressed with the tab completion and typing experience (felt like laggy typing on a remote server).

  • VS Code with standard copilot for tab completion and Aider in a terminal window for all the heavier lifts, asking questions, architecting etc. And it’s cheap! I’ve been using it with OpenRouter (lets you easily switch models and providers) and my $10 of credits lasted weeks. Granted, I also use Claude a lot in the browser.

    • The reason many prefer Cursor over VSCode + GitHub Copilot is because of how much faster Cursor is for tab completion. They use some smaller models that are latency optimized specifically to make the tab completion feel as fast as possible.

  • If you don't mind leaving VSCode I'm a huge fan of Zed. Doesn't support some languages / stacks yet but their AI features are on-par with VSCode

    • That's the wrong IDE to compare it to though, Cursor's AI features are 10x better than VSCode's. I tried Zed last month and while the editing was great, the AI features were too half-baked so I ended up going back to Cursor. Hopefully it gets better fast!

  • Agreed. My laptop has never used swap until I started using cursor… it’s a resource hog, I dislike using it, but it’s still the best AI coding aid and for the work I’m doing right now, the speed boost is more valuable than hand crafted code in enough cases that it’s worth it for me. But I don’t enjoy using the IDE itself, and I used vscode for a few years.

    Personally, I will jump ship to Zed as soon as it’s agent mode is good enough (I used Zed as a dumb editor for about a year before I used cursor, and I love it)

  • I switched to Windsurf.ai when cursor broke for me. Seems about the same but less buggy. Haven't used it in the last couple weeks, though, so YMMV.

    • I found the Windsurf agent to be relatively less capable, but their inline tool (and the “Tab” they’re promoting so much) has been extremely underwhelming, compared to Cursor.

      The only one in this class to be even worse in my experience is Github Copilot.

  • cant bother fixing their issues because they are too busy vibe coding new features

  • Cursor + Vim plugin never worked for me, so I switched back to Nvim and never looked back. Nvim already has: avante, codeCompanion, copilot, and many other tools + MCP + aider if you're into that.

  • Last I heard their team was still 10 people. Best size for doing something revolutionary. Way too few people to triage all that many issues and provide support.

    They have enough revenue to hire, they probably are just overwhelmed. They'll figure it out soon I bet.

  • Any competing product has to absolutely nail tab autocomplete like Cursor has. It's super fast, very smart (even guessing across modules) and very often correct.

  • Claude Code CLI is amazing and I am very confused as to why no one in 24 hours has recommended it.

Cursor sucks. Not as a product. As a team. Their customer support is terrible.

I was offered in writing a refund by the team who cold reached out to me to ask me why I cancelled my sub one week after start. Then they ignored my 3+ emails in response asking them to refund, and other means of trying to communicate with them. Offering me a refund as a bait to gain me back, then when I accept it they ghost me. Wow. Very low.

The product is not terrible but the team responses are. And this, if you see how they handled it, is also a very poor response. First thing you notice if you open the link is that the Cursor team removed the reddit post! As if we were not going to see it or something? Who do they think they are? Censoring bad comments which are 100% legit.

I am giving it a go to competitors just out of sheer frustration with how they handle customers, and I do recommend everybody to explore other products before you settle on Cursor. I don't intend to ever re-subscribe and have recommended friends to do the same, most of which agree with my experience.

  • sounds like perfect grounds for a chargeback to me. Company offered a full refund via one of its Agents, company then refused to honour that offer, time to make your bank force them to refund you.

    Just because you use AI for customer service doesn't mean you don't have to honour its offers to customers. Air Canada recently lost a case where its AI offered a discount to a customer but then refused to offer it "IRL"

    https://www.forbes.com/sites/marisagarcia/2024/02/19/what-ai...

  • Same exact thing happened to me. I tried out Vursor after hearing all the hype and canceled after a few weeks. Got an email asking if I wanted a refund and asking for any feedback. I replied with detailed feedback on why I canceled and accepted the refund offer, then never heard back from them.

  • Interesting. The same thing happened to me. Was offered a refund (graciously, as I had forgotten to cancel the subscription). And after thanking them and agreeing to the refund, was promptly ignored!

    Very strange behavior honestly.

  • I had the same exact experience - after disappointment (couldn't use like 2/3 of my premium credits because every second request failed after they upgraded to 0.46) unsubscribed. They offered refund in email. I replied I wanted refund but no reply

    • Apparently they use AI to read emails. So the future of email will be like phone support now, where you keep writing LIVE AGENT until you get a human responding.

  • This reminds me of how small of a team they are, and makes me wonder if they have a customer support team that's growing commensurately with the size of the user base.

I just cancelled - not because I thought the policy change was real - but simply because this article reminded me I hadn't used it much this month.

  • This is where Kagi’s subscription policy comes in handy. If you don’t use it for a month, you don’t pay for it that month. There is no need to cancel it and Kagi doesn’t have to pay user acquisition costs.

    • Slack does this as well. It's a genius idea from a business perspective. Normally IT admins have to go around asking users if they need the service (or more likely you have to request a license for yourself), regularly monitor usage, deactivate stale users etc., all to make sure the company isn't wasting money. Slack comes along and says - don't worry, just onboard every user at the company. If they don't log in and send at least N messages we won't bill them for that month.

    • That's a fun one. It could be interpreted as a generous implementation of a monthly subscription, or a hostile implementation of a metered plan.

    • surely the first thing you do when you subscribe to Kagi is set your default browser search to Kagi.

  • so the old adage no such thing as bad PR shows to be incorrect. had they not been in the news, they'd at least have gotten one more monthly sub from you!

    • This would only be complete in aggregate. We don’t know how many people signed up as a result.

Cursor is trapped in a cat and mouse game against "hacks" where users create new accounts and get unlimited use. The repo was even trending on Github (https://github.com/yeongpin/cursor-free-vip).

Sadly, Cursor will always be hampered by maintaining it's own VSCode fork. Others in this niche are expanding rapidly and I, myself, have started transitioning to using Roo and Cline.

  • literally any service with a free trial--i.e. literally any service--has this "problem". it's an integral part of the equation in setting up free trials in the first place, and by no means a "trap". you're always going to have a % of users who do this, the business model relies on the users who forget and let the subscription cross over to the next month or simply feel its worth paying

    • This is true but Cursor’s problems are a bit worse than a normal paywalled service.

      Cursor allows users to get free credits without a credit card and this forced them to change their VSCode fork on how it handles identification so they can stop users from spawning new accounts.

      Another is that normally, companies have a cost for each free user. For Cursor, this cost is so sporadic since it doesn’t charge per million context, they use credits. Free users get 50 credits but 1 credit could be 200k+ context each so it could be $40-50 per free user per month. And these users get 50 credits every month.

      Lastly, the cursor vip free repo has trended on GitHub many times and users who do pay might stop and use this repo instead.

      The Cursor vip free creator is well within his rights to do what they want and get “free” access. This unfortunately hurts paying customers since Cursor has to stop these “hacks.”

      This is why Cursor should just move to a VSCode extension. I’ve used Augment and other VSCode extensions and the feature set is close to Cursor so it’s possible for them just to be an extension. The other would be to remove free accounts but allow users to bring their own keys. To use Composer/Agent, you can’t bring your own keys.

      This will allow Cursor to stop maintaining a VSCode fork, helps them stop caring if users create new accounts (since all users are paying) and lets users bring their own keys if they don’t want to pay. Hell, if they charge a lifetime fee to bring our own keys for Agent, that would bring in revenue too. But as I see now, Roo and Cline’s agent features are catching up and Cursor won’t have a moat soon.

  • > Cursor is trapped in a cat and mouse game against "hacks" where users create new accounts and get unlimited use

    Actually, you don't even have to make a new account. You can delete your account and make it again reusing the same email.

    I did this on accident once because I left the service and decided to come back, and was surprised to get a free tier again. I sent them an email letting them know that was a bug, but they never responded.

    I paid for a month of access just to be cautious, even though I wasn't using it much. I don't understand why they don't fix this.

  • What I don't understand is why maintain a fork instead of just an extension? I would assume an extension like this would be pretty difficult to create but would it be more difficult than literally forking VSCode?

    • Cursor was one of the first AI editors and there was no way to add those features to VSCode thru extensions at that time. Another issue was that VSCode made special exceptions and opened APIs for CoPilot, Microsoft’s product, but not for other players. Not sure if this has changed now.

      Cursor took the best course of action at the time by forking but needs to come back into the fold. If VSCode is restricting access to APIs to CoPilot, forking it publicly and putting that in the Readme, “We forked VSCode since they give preferential treatment to CoPilot” would get a lot of community support.

  • There will be a fork-a-month for these products until they have the same lockin as a textbox that you talk at, "make million dollar viral facebook marketplace post"

What is the evidence that "dozens of users publicly canceled their subscriptions"?

A total of 4 users claimed that they did or would cancel their subscriptions in the comments, and 3/4 of them hedged by saying that they would cancel if this problem were real or happened to them. It looks like only 1 person claimed to have cancelled already.

Is there some other discussion you're looking at?

  • Submitted title was "Cursor IDE support hallucinates lockout policy causes mass user cancellations" - I've de-massed it now.

    Yet if you went by the HN comments, you'd think it were the biggest item on primetime news.

    People are really champing at the bit.

    • Currently, there are 59 comments after the post was deleted and the thread was locked.

      It is worth mentioning that the comments that remain are valuable, as they highlight the captured market size and express concern about the impending deterioration of the situation.

From the top Reddit post:

> Apologies about the confusion here.

If this was a sincere apology, they'd stop trying to make a chat bot do support.

This drama is a very good thing because 1) now companies might reconsider replacing customer support with AI and 2) the initial victim was an AI company.

It could be better though.. I wish this happened to a company providing "AI support solutions"..

  • A company of 10 devs might not actually have a customer support at all. We all know, devs are not the greatest customer support people.

  • It's an AI company that is presumably drowning in money. What humans do work there have probably already had a good laugh and forgotten about this incident.

Yup, hallucinations are still a big problem for LLMs.

Nope, there's no reliable solution for them, as of yet.

There's hope that hallucinations will be solved by someone, somehow, soon... but hope is not a strategy.

There's also hype about non-stop progress in AI. Hype is more a strategy... but it can only work for so long.

If no solution materializes soon, many early-adopter LLM projects/trials will be cancelled. Sigh.

  • trying to "fix hallucinations" is like trying to fix humans being wrong. it's never going to happen. we can maybe iterate towards an asymptote, but we're never going to "fix hallucinations"

    • No: an LLM that doesn't confabulate will certainly get things wrong in some of the same ways that honest humans do - being misinformed, confusing similar things, "brain" damage from bad programming or hardware errors. But LLM confabulations like the one we're discussing only occur in humans when they're being sociopathically dishonest. A lawyer who makes up a court case is not a "human being wrong," it's a human lying, intentionally trying to deceive. When an LLM does it, it's because it is not capable of understanding that court cases are real events that actually happened.

      Cursor's AI agent simply autocompleted a bunch of words that looked like a standard TOU agreement, presumably based on the thousands of such agreements in its training data. It is not actually capable of recognizing that it made a mistake, though I'm sure if you pointed it out directly it would say "you're right, I made a mistake." If a human did this, making up TOU explanations without bothering to check the actual agreement, the explanation would be that they were unbelievably cynical and lazy.

      It is very depressing that ChatGPT has been out for nearly three years and we're still having this discussion.

  • One workaround for using RAG, as mentioned in a podcast I listened to, involves employing a second LLM agent to assess the work of the first LLM. This agent evaluates the response or hallucination by requiring the first LLM to cite sources and subsequently locate those sources.

I have an uneasy feeling logging into a Text Editor vscode and seeing a Microsoft correlated account, work or personal, in the lower left corner. I understand that settings sync or whatever but it’d be preferred to keep to a simple config json or xml (pretty sure most settings are in json).

I have no problem, however, pasting an encryption public key into my Sublime Text editor. I’m not completely turned off by ability fir telemetry, tracking, or analytics. But having a login for a Text Editor is totally unappealing to me with all the overhead.

It’s a bummer that similar to browsers and chrome, the text editor with an active package marketplace necessitates some tech major underwriting the development with “open source” code but a closed kernel.

I've had a very good experience with Cursor on small Typescript projects.

It started hallucinating a lot as my typescript project got bigger.

I found it pretty useless in languages like Go and C++.

I ended up canceling Cursor this month. It was messing up working code, suggesting random changes, and ultimately increasing my cognitive load instead of reducing it.

Remember: They think you should trust their AI's output with your codebase.

AI bubble popping yet? Looking forward to not buying GPUs that cost $2K (before tariffs…).

  • AI's killer app is "marketing". Bots are incredibly useful for selling items, services, and politics, and AI makes the bots indistinguishable from real people to most people most of the time. It's highly effective so I don't see that market shrinking any time soon.

  • [flagged]

    • There’s a bubble, in the sense of the dot-com bubble. There’s a lot of money being thrown at the AI equivalents of Pets.com, and that will pop eventually. But the internet persisted and transformed every aspect of the society even after the bubble. I think AI will be similar.

    • AI has historically gone through bubbles, AI Winter is a term exactly because of these cycles of hype.

      Maybe this time is different. Maybe not.

  • 1) there is no AI bubble, it has revolutionized how we communicate and learn 2) you don't need to buy an expensive GPU for local LLM, any contemporary laptop with enough RAM is sufficient to run an uncensored Gemma-3 fast

    • Railroads revolutionized transport and yet railway mania was undeniably a bubble. Something can be both very useful and yet also overvalued and overhyped leading to significant malinvestment (sometimes, everyone wins to the detriment of the investors, sometimes just everyone loses out because a huge amount of effort was spent on not useful stuff, usually somewhere in between).

    • I'm shocked by this perspective, and I'm deep into the LLM game (shipped 7 figure products using LLMs). I don't feel like anything has been revolutionized around communication - I can spot AI generated emails pretty easily (just send the prompt, people). On the learning front I do find LLMs to be more capable search engines for many tasks, so they're helpful absolutely.

    • I'm an AI fan, but there's clearly a desperate attempt by just about every tech company to integrate AI at the cost of genuinely productive developments in the space, in a manner that one might describe as a "bubble." Microsoft's gotta buy enough GPUs to handle Copilot in Windows Notepad, after all...

LLMs for customer support is for ghetto companies that want to cheap out on quality. That's why you'll see Comcast and such use it, for example, but not your broker or anywhere where the stakes on the company's reputation are non-zero.

Some time ago, in an electronics online shop I asked about warranty terms from a chatbot and got favorable answers. It didn't take two hours before a human contacted me via email to correct a misunderstanding.

Awesome. It warms my heart that both parties who are supporting AI, users and company, felt its negative effects. We can only hope this continues to happen.

I do a few AI projects and my number one rule is to use LLMs only to process requests and never to generate responses.

god I hate redditors. what is it about that website that makes every user so so incredibly desperate to jump on literally any bandwagon they can lay their woolly arses on?

A huge problem. I think AI-based customer service is more negative than positive in general. In my opinion in this way we first of all entrust an operation that needs to be timely and above all empathetic to AI; secondly, although it is faster to train a model to become a very good customer assistant, thereafter a continuous human intervention of monitoring, improvement and error correction is required. So in the end, in addition to not having a customer assistant capable of “being close” to the customer and understanding the finer nuances of a customer's request, this approach leads to inefficiency and slowdowns in the medium to long term.

Literally the only safe way to use an LLM in a business context is as an input to a trusted human expert, and the jury is still out for even that case.

Letting an AI pose as customer support is just begging for trouble, and Cursor had their wish appropriately granted.

The coverup is worse than the crime. Truly, man has made machine in his image.

This is "AGI's finest".

It's what we all wanted. Replacing your human support team to be run exclusively by AI LLM bots whilst they hallucinate to their users. All unchecked.

Now this bug has now turned into a multi-million dollar mistake and costed Cursor to lose millions of dollars overnight.

What if this was a critical control system in a hospital or energy company and their AI support team (with zero humans) hallucinated a wrong meter reading and overcharged their customers? Or the AI support team hallucinated the wrong medication to a patient?

Is this the AGI future we all want?

  • Are we sure that the damage is in “millions”? Could it not be just the same old “vocal and loud minority”, who will wake up tomorrow and re-activate their subscription before the lunch break once Cursor team comes and writes a heartfelt apology post (well generated by AI with a system prompt of “you are a world class PR campaign manager …”)?

  • You're right, but this is more general - it has nothing to do with AGI and everything to do with poor management. It reminds me very much of the Chernobyl disaster, and the myriad examples in Taleb's "The Black Swan".

  • It's a Reddit post with 65 upvotes. Where are people getting millions of dollars overnight? HN is too dramatic lol

    • Even if they generously compensate locked out users, they'll probably end up ahead using the AI bot.

I love this moment so much, I want to marry it and raise a family of little moments with it. A company that claims AI will solve everything cannot even get their own support right. chefkiss

A question to the HN community. Is there any profit in running web sites like they were designed during peak web(~2007)?

No AI, less crappy frameworks, fewer dark patterns, etc.

> And just as people started comparing notes and figuring out that the story didn’t quite add up… the main Reddit thread got locked. Then deleted. Like, no public resolution, no real response, just silence.

Anything that doesn't fit the narrative must be deleted I guess.

As is so often the case, it's not the mistake itself that's the biggest problem but how people or organisations deal with the mistake.

I was playing around with ChatGPT the other day and encountered a similar issue. Once I hit the rate limit, the replies telling me that seemed to be AI generated. When I waited the requisite time, the next use attempt repeated the last message about being past the limit and needing to wait 13 hours again.

It seemed to be reading from the conversation to determine this. Oops! Replaying an earlier message worked fine.

If you've ever worked in support you would know that even the most technical people can be highly inarticulate, have an inability to share even the most basic details, and if English isn't their first language things can get very confusing. An AI bot answering those people with a lack of context and pretending to be a real support agent is an accident waiting to happen.

That's probably not so bad in a culture based on lies, like the US or China. That's probably their training data. But it wouldn't fly in more robust cultures were you expect the truth, even if it we will hurt.

Oooh I wanted to try this for a while so here goes…

This doesn’t seem like anything new. Ill-informed support staff has always existed, and could also give bad information to users. AI is not the problem. And it hasn’t created any problems that weren’t already there before AI.

Usually by the time I get to a post on HN criticizing AI, someone has already posted this exact type of rebuttal to any criticism…

This comes on the heels of researchers putting javascript backdoors in AI assisted programs made in cursor using poisoned includes as well.

I disagree with but understand selling AI as a hot thing that can reliably do things to other companies. False marketing has been around since "buh buh" sold a deer corpse to "bah bah" in exchange for his pretty leaf mat by telling him it's actually a cow.

But drinking the kool aid yourself? That demonstrates a new low in human mental facility.

Consider the source. I assume companies will learn the hard way not to fake human interaction and be forced to mention when responses are auto-generated (a better word than "AI" really). All that effort for so many to build rapport and trust and all pissed away by trying to save a buck and having an ambitious bot trying to go solo.

I haven't seen people comment on just the wow factor here. Apparently Cursor produced a full integrated AI app and it orchestrated a self-destruct process in fashion emulating the way some human-managed companies have recently self-destructed. AI fails are easy and some require a lot of work, apparently.

Looking forward to apps trained on these Reddit threads.

  • Who will be the first AI-first company to close the loop with autonomous coding bots, and create self-fulfilling prophecies where a customer support bot hallucinates a policy like OP, it gets stored in the Q&A/documentation retrieval database, and the autonomous bots implement and roll out the policy and lock out all the users (and maybe the original human developers as well)?

I don't understand the negativity. I use Cursor and love it.

Are there real challenges with forking VS Code? Yep. Are there glitches with LLMs? Sure. Are there other AI-powered coding alternatives that can do some of the same things? You betcha.

But net-net, Cursor's an amazing power tool that strongly extends what we can accomplish in any hour, day, or week.

  • > I don't understand the negativity.

    AI replied to support email, and told people a session bug was a feature.

    • No, I get that. But that obvious screw-up is being conflated with assessments of "is Cursor any good?" "is Cursor still ahead of the pack?" "does LLM-assisted coding good/useful?" et cetera.

      This one failure is kitchen-sinking into a broad list of grievances, perceived slights, or unrelated problems all at once. I don't understand that, since I'm finding Cursor to be strong, helpful, and constantly improving. My experience is entirely different from this list of grievances.

I wonder if people are wrongly just going to start calling random, completely-unrelated-to-LLM bugs in software "hallucination". Very similar to the meaning of AI changing in recent years to include basically any software that has some type of algorithm or heuristic built into it.

>Community was in revolt

>Dozens of users publicly cancelled

A bit hyperbolic, no? Last I read they have over 400,000 paying users.

Local only bots or bust. Stop relying on SaaS! Cloud is synonym for just somebody else's system!

  • Are you using a locally ran LLM that is equally capable as Claude 4.7? Kind of seems like the answer has to be "not as capable and also the hardware investment was insane"

> most surreal product screwups

It seems you're not aware of the issue which plagued tens of Cursor releases, where the software would auto-delete itself on updates.

It was pretty hilarious, to be honest. Your workflow would consist of always installing the editor before use.

FWIW, to illustrate how insane and risky it is to use an AI bot deceptively pretending to be a human as the first line of customer support, I was just asking ChatGPT 4.5 Research Preview analyze the reddit and hn threads about Cursor's horrible AI customer service bot, pasting them in part by part, and finally writing this prompt:

I said:

[Pasted reddit and hn discussion in pieces asking it to hold off commenting until I told it that was all.]

>Ok that is all, now please summarize all the points people raise and interesting discussions. In DETAIL! Write a full deep research report on this and the original reddit discussion, with quotes naming the users who say it, summarizing important back-and-forth threads. You can omit unimportant trolls and inane chit chat.

ChatGPT said:

>The Kurdistan Workers' Party (PKK) is designated as a terrorist organization by several countries and international bodies. The European Union, the United States, and Turkey have officially listed the PKK as a terrorist organization. This designation is based on the group's history of armed conflict and attacks, particularly in Turkey.

>The PKK has been involved in an armed struggle against the Turkish state since the 1980s, seeking greater autonomy and rights for Kurds in Turkey. This conflict has resulted in significant violence and loss of life over the decades.

>While the PKK is designated as a terrorist organization by the EU, the U.S., and Turkey, other countries may have different stances or may not have made an official designation. It's important to consult the specific policies of each country for their official position on the PKK.

>Sources

I said:

>What does your response have to do with a discussion of Cursor's AI customer service?

ChatGPT said:

>You're right—my previous response about the PKK had nothing to do with the discussion about Cursor's AI customer service issue. It seems that I mistakenly pasted content unrelated to our current topic.

>Let me properly address your original request by summarizing in detail the issues raised in the discussions regarding Cursor's AI customer service: [...]

It makes me wonder who got the summary of the reddit and hn discussions in response to their question about terrorist organizations, and what that makes them think about Cursor as a company, and their involvement in armed struggles, international politics, and terrorism?

The original bug that prevented login was no doubt generated by AI. They probably ran it through an AI code review tool like the one posted here recently.

The world is drowning in bullshit and delusion. Programming was one of the few remaining places where you had to be precise, where it was harder to fool yourself. Where you had to understand it to program it. That's being taken away and it looks like a lot of people are embracing what is coming. It's hardly surprising - we just love our delusions too much.

  • Or, alternatively, it was a bug written by a human. Humans do a good enough job making bugs, no?

  • I’d love to visit the alternate universe you inhabit where there are no bugs in human written code.

    • at no point did they say anything that even comes close to saying “no bugs in human written code.”

      if you’re willing to come down off your defensive AI position, because your response is a common one from people who are bought into the tech, i’ll try explain what they were saying (if not, stop reading now, save yourself some time).

      maybe you’ll learn something, who knows :shrug:

      > Programming was one of the few remaining places where you had to be precise, where it was harder to fool yourself. Where you had to understand it to program it.

      they are talking about the approach, motivations and attitudes involved in “the craft”.

      we strive for perfection, knowing we will never reach it. we, as programmers/hackers/engineers must see past our own bullshit/delusions to find our way to the fabled “solution”.

      they are lamenting how those attitudes have shifted towards “fuck it, that’ll do, who cares if the code reads good, LLM made it work”.

      where in the “vibe coding” feedback loop is there a place for me, a human being, to realise i have completely misunderstood a concept for the last five years and suddenly realise “oh shit, THATS HOW THAT WORKS!? HOW HAVE I NOT REALISED THAT FOR FIVE YEARS.” ?

      where in “just ask chatgpt for a summary about a topic” is my journey where i learn about a documentation rendering library that i never even knew existed until i actually started reading the docs site for a library?

      maybe we were thinking about transferring our docs off confluence onto a public site to document our API? asking chatGpt removes that opportunity for accidental learning and growth.

      in essence, they’re lamenting the sacrifice people seem to be willing to make for convenience, at the price of continually growing and learning as a human being.

      at least that’s my take on it. probably wrong — but if i am at least i get to learn something new and grow as a person and see past my own bullshit and delusions!

This is extremely funny. AI can't have accountability. Good luck with that.

Use AI to augment but don't really replace it as a 100% system if you can't predict and own up the failure rate.

My advice would be to use more configurable tools with less interest on selling fake perfection. Aider works.

  • > AI can't have accountability

    Sure it can. You just have to bake into the reward function "if you do the wrong thing, people will stop using you, therefore you need to avoid the wrong thing".

    Then you wind up at self-preservation and all the wholly shady shit that comes along with it.

    I think the AI accountability problem is the crux of the "last-mile" problem in AI, and I don't think you can necessarily solve it without solving it in a way that produces results you don't want.

    • I don't want to get into a semantics argument but that's not accountability. That's just one more behavior prompt/indication but you can't fire the LLM. It might still do the wrong thing.

Incidentally, this is a great way to find out you're never going to get real support when you need it, just AI responses designed to make you get tired of trying to talk to a real person they need to pay.

The current AIs are such people pleasers, that I really take the time how to form the prompt, so that it can't just say, "yes, it is like that" in a polite way.

What's the best llm-first/ designed with llm in mind editor? Is it still cursor?

There's windsurf, cline, zed, copilot got a huge update too, is cursor still leading the space?

Cursor is bevoming useless now. They are too money greedy to be trusted. Last time i installed on another machine tgey told me to subscrribe to use. It is gross.

> Not because they made a mistake

Except they did make a mistake: trusting their Simulated Intelligence (I’m done calling it “AI”.) with their customers’ trust.

If you use AI to generate any communication, you are still fully responsible for it. It's still your communication, just using a tool.

cursor got there first, but it’s just not that good. stuff not built on top of vscode feels much more promising. i’ve been enjoying zed.

I fear the day when legal matters and other impactful decisions are decided and similarly hallucinated by AI.

Can't move fast and break things unless you do stuff that breaks things. In this case customer trust.

> Dozens of users publicly canceled their subscriptions, myself included.

Makes you think of that one meme.

Who would have predicted turning customer support over to AI with no human interv

nah this is wild, imagine AI company 'automate' their most critical software

surely it wouldn't backfire, right???

ok aside from the joke from this case alone, I think we can all agree that AI not replacing human soon

I am shocked. Really? In the beginning of AI hype, as a product designer, I moved to my routine. Research. You don't need a PHD to find people smarter than you and experts to explain to you what 'stochastic parrots' means.

To understand how LLM's work and why the hallucination is inherent part of the tech with "AI". Maybe the core problem is implementation practices which remove critical thinking and testing? Maybe the core problem is 'fake it till you make it' ideology? I don't know. But I am sure about one thing. This as any other postmodern technology will bring more problems than solutions.

Good. I hope other companies stupid enough to subject their users to unleashed AI for support instead of real humans reap the consequences of their actions. I'll be eating popcorn and mocking them from my little corner of the internet.

1. Whenever AI is used closed loop, with human feedback and a human checking the output for quality/hallucinations and then passing it along, it's often fine.

2. Whenever it is used totally on its own, with no humans in the loop, it's awful and shit like this happens.

Yet, every AI company seems to want to pretend we're ready for #2, they market their products as #2, they convince their C-suite customers that their companies should buy #2, and it's total bullshit--we're so far from that. AI tools can barely augment a human in the driver's seat. It's not even close to being ready to operate on its own.

But look, AI did take a job today. The job of cursor product developers is gone now. ;) But seriously, every time I hear media telling me AI is going to replace us, they conveniently forget episodes like this. AI may take the jobs one day, but it doesn't seem like that day is any time soon when AI adopters keep getting burned.

I love Cursor. I use it daily. My company, Leela AI, is building on top of it — with MCP tools, Cursor and VSCode plugins, our own models, integrated real-time video analysis, and custom vision model development, query, and action scripting systems.

We're embedding "Active Curation" into the workflow: a semi-automated, human-guided loop that refines tickets, PRs, datasets, models, and scripted behaviors in response to real-world feedback. It's a synergistic, self-reinforcing system — every issue flagged by a user can improve detection, drive model updates, shape downstream actions, and tighten the entire product feedback loop across tools and teams.

So consider this tough love, from someone who cares:

Cursor totally missed the boat on the customer support hallucination fiasco. Not just by screwing up the response — that happens — but by failing to turn the whole mess into a golden opportunity to show they understand the limits of LLMs, and how to work with those limits instead of pretending they don’t exist.

They could have said: Here’s how we’re working to build an AI-powered support interface that actually works — not by faking human empathy, but by exposing a well-documented, typed, structured interface to the customer support system.

You know, like Majordomo did 30 years ago, like GitHub did 17 years ago, or like MCP does now — with explicit JSON schemas, embedded documentation, natural language prompts, and a high-bandwidth contract between the LLM and the real world. Set clear expectations. Minimize round trips. Reduce misunderstandings.

Instead? I got ghosted. No ticket number. No public way to track my issue. I wrote to enterprise support asking specifically for a ticket number — so I could route future messages properly and avoid clogging up the wrong inboxes — and got scolded by a bot for not including the very ticket number I was asking for, as if annoyed I'd gone around its back, and being dense and stubborn on purpose.

You play with the Promethean fire of AI impersonating people, that's what you get, is people reading more into it than it really means! It's what Will Wright calls the "Simulator Effect" and "Reverse Over-Engineering".

https://donhopkins.medium.com/designing-user-interfaces-to-s...

Eventually, after being detected trying to get through on the corporate email address, I was pawned off to the hoi polloi hi@cursor.com people-bot instead of the hoi aristoi enterprise@cursor.com business-bot. If that was a bot, it failed. If it was a human, they wrote like a bot. Either way, it's not working.

And yes — the biggest tell it wasn't a bot? It actually took hours to days to respond, especially on weekends and across business hours in different time zones. I literally anthropomorphized the bot ghosting into an understandably overworked work-life-balanced human taking a well earned weekend break, having a sunny poolside barbecue with friends, like in a Perky Pat Layout, too busy with living their best life to answer my simple question: "What is the issue ID you assigned to my case, so we can track your progress?" so I can self serve and provide additional information, without bothering everyone over email. The egg is on my face for being fooled by a customer support bot!

Cursor already integrates deeply with GitHub. Great. They never linked me to any ticketing system, so I assume they don't expose it to the public. That sucks. They should build customer support on top of GitHub issues, with an open-source MCP-style interface. Have an AI assistant that drafts responses, triages issues, suggests fixes, submits PRs (with tests!) — but never touches production or contacts customers without human review. Assist, don’t impersonate. Don’t fake understanding. Don’t pretend LLMs are people.

That’s not just safer — it’s a killer dev experience. Cursor users already vibe-code with wild abandon. Give them modular, extensible support tooling they can vibe-code into their own systems. Give them working plugins. Tickets-as-code. Support flows as JSON schemas. Prompt-driven behaviors with versioned specs. Be the IDE company that shows other companies how to build world-class in-product customer support using your own platform fully integrated with GitHub.

We’re doing this at Leela. We'd love to build on shared open foundations. But Cursor needs to show up — on GitHub, in issue threads, with examples, with tasty dogfood, and with real engineering commitment to community support.

Get your shit together, Cursor. You're sitting on the opportunity of a generation — and we’re rooting for you.

Four hours and 34 minutes from sending that I finally got a response from a human (or a pretty good simulation), who actually read my email, and started the process of solving my extremely simple and stupid problem, which my initial messages -- if anyone read them or ran a vision model on all the screen snapshots I provided -- would have given them enough information to easily solve the problem in one shot.

I've been saying this for years; LLMs will never be able to replace a good support staff. The only support LLMs can be relied on for is the kind of support you get from companies like google and netflix. Off-shored, glorified clickfarm workers in India, who only have access to some restrictive API and a very rigid playbook. They can do stuff like grandma forgot her password again -> help her reset her password.

For a support agent to actually be useful beyond that, they need some leeway to make decisions unilaterally, sometimes in breach of "protocol", when it makes sense. No company with a significant level of complexity in its interactions with customers can have an actually complete set of protocols that can describe every possible scenario that can arise. That's why you need someone with actual access inside the company, the ability to talk to the right people in the company should the need arise, a general ability(and latitude) to make decisions based on common sense, and an overall understanding of the state of the company and what compromises can be made somewhat regularly without bankrupting it. Good support is effectively defined by flexibility, and diametrically opposed to following a strict set of rules. It's about solving issues that hadn't been thought of until they happened. This is the kind of support that gets you customer loyalty.

No company wants to give an LLM the power given to a real support agent, because they can't really be trusted. If the LLM can make unilateral decisions, what if it hallucinated and gives the customer free service for life? Now they have to either eat the cost of that, or try to withdraw the offer, which is likely to lose them that customer. And at the end of all that, there's no one to hold liable for the fuckup(except I guess the programmers that made the chatbot). And no one wants the LLM support agent to be sending them emails all day the same way a human support agent might. So what you end up with is just a slightly nicer natural language interface to a set of predefined account actions and FAQ items. In other words, exactly what you get from clickfarms in Southern Asia or even a phone tree, except cheaper. And sure, that can be useful, just to filter out the usual noise, and buy your real support staff more time to work on the cases where they're really needed, but that's it.

Some companies, like Netflix and Google(Google probably has better support for business customers, never used it, so I can't speak to it. I've only Bangalored(zing) my head against a wall with google support as a lowly consumer who bought a product), seem to have no support staff beyond the clickfarms, and as a result their support is atrocious. And when they replace those clickfarms with LLMs, support will continue to be atrocious, maybe with somewhat better English. And it'll save them money, and because of that they'll report it as a rousing success. But for customers, nothing will have changed.

This is pretty much what I predicted would happen a few years ago, before every company and its brother got its own LLM based support chatbot. And anecdotally, that's pretty much what has happened. For every support request I've made in the last year, I can remember 0 that were sorted out by the LLM, and a handful that were sorted out by humans after the LLM told me it was impossible to solve.

From cursor developer: "Hey! We have no such policy. You're of course free to use Cursor on multiple machines.

Unfortunately, this is an incorrect response from a front-line AI support bot. We did roll out a change to improve the security of sessions, and we're investigating to see if it caused any problems with session invalidation. We also do provide a UI for seeing active sessions at cursor.com/settings.

Apologies about the confusion here."

  • lol this is totally the kind of company you should be giving money too

    • and the best thing about it is that the base model is going to be trained on reddit posts so expect SupportBot3000 to be even more confident about this fact in the future!

    • I mean to be fair, I like that they're putting their money where their mouth is so to speak - if you want to sell a product based on the idea that AI can handle complex tasks, you should probably have AI doing what should be simple, frontline support.

Cursor: a VS Code extension that got itself valued at $10bn.

  • The 1 million users + $200 million in revenue probably had something to do with the valuation.

    • Slack was a similar thing. IPO'd at 10 million users with 400M in revenue but got destroyed by Microsoft thanks to Teams.

      Cursor is at a worse position and at greater risk of ending up like Slack very quickly and Microsoft will do the exact same thing they did to Slack.

      This time by extinguishing (EEE) them by racing prices of VSCode + Copilot close to zero, until it is free.

      The best thing Cursor should do is for OpenAI to buy them at a $10B valuation.

Fingers crossed the users will go left are all the noisy ones. I still enjoy using Cursor but their forum is filled with too many posts about $20 being too expensive or they need to raise caps or Cursor is the worse tool in the world.

A few hallucinations. It's right more times than it's wrong. Humans make mistakes as well. Cosmic justice.

  • Yes, but humans can be held accountable.

    • I probably should have added sarcasm tags to my post. My very firm opinion is that AI should only make suggestions to humans and not decisions for humans.

    • I'd argue that humans also more easily learn from huge mistakes. Typically, we need only one training sample to avoid a whole class of errors in the future (also because we are being held accountable).

    • As annoying as it is when the human support tech is wrong about something, I'm not hoping they'll lose their job as a result. I want them to have better training/docs so it doesn't happen again in the future, just like I'm sure they'll do with this AI bot.

    • How is this not an example of humans being held accountable? What would be the difference here if a help center article contained incorrect information? Would you go after the technical writer instead of the founders or Cursor employees responding on Reddit?

Wow, so much negativity. The Cursor team has built a wonderful product — and they made a mistake. Now haters are trying to rip it apart because of one mistake. Yeah, I also paid for the yearly plan. Yeah, I was also annoyed to get locked out on another device. Was it annoying? Yes. But will I abandon the product? No, not because of this. Chill, folks. Get a life.

  • Sorry but this screams copium. Its right in your face why cursor is bad, and your response is "but the product is good". Is it? What did they do better than e.g. aider, claude code and zed? What makes them stand out?

    I honestly don't get it, but if you want to support such a lazy team then have at it, no one's stopping you

    • You are aggressive and rude. They didn’t sell you a house. It’s a product that costs 20 usd a month. I know all other products and prefer Claude Code. But it is expensive. I burn 20-40 USD in a single session. And I find Cursor pretty good. Better than the alternatives, minus Claude Code.
