I have no doubts that it does for many people. But the time/cost tradeoff is still unquestionable. I know I could create what LLMs do for me in the frontend/backend in most cases as good or better - I know that, because I've done it at work for years. But to create a somewhat complex app with lots of pages/features/apis etc. would take me months if not a year++ since I'd be working on it only on the weekends for a few hours. Claude code helps me out by getting me to my goal in a fraction of the time. Its superpower lies not only in doign what I know but faster, but in doing what I don't know as well.
I yield similar benefits at work. I can wow management with LLM assited/vibe coded apps. What previously would've taken a multi-man team weeks of planning and executing, stand ups, jour fixes, architecture diagrams, etc. can now be done within a single week by myself. For the type of work I do, managers do not care whether I could do it better if I'd code it myself. They are amazed however that what has taken months previously, can be done in hours nowadays. And I for sure will try to reap benefits of LLMs for as long as they don't replace me rather than being idealistic and fighting against them.

This has been my experience. We use Miro at work for diagramming. Lots of visual people on the team, myself included. Using Miro's MCP I draft a solution to a problem and have Miro diagram it. Once we talk it through as a team, I have Claude or codex implement it from the diagram.
It works surprisingly well.

Of course they're amazed. They don't have to pay you for time saved ;)

I think this is the part that people are worried about. Every engineer who uses LLMs says this. By definition it means that people are being replaced.
I think I justify it in that no one on my team has been replaced. But management has explicitly said "we don't want to hire more because we can already 20x ourselves with our current team +LLM." But I do acknowledge that many people ARE being replaced; not necessarily by LLMs, but certainly by other engineers using LLMs.
I'm still waiting for the multi-years success stories. Greenfield solutions are always easy (which is why we have frameworks that automate them). But maintaining solutions over years is always the true test of any technologies.
It's already telling that nothing has staying power in the LLMs world (other than the chat box). Once the limitations can no longer be hidden by the hype and the true cost is revealed, there's always a next thing to pivot to.
Comments like these really help ground what I read online about LLMs. This matches how low performing devs at my work use AI, and their PRs are a net negative on the team. They take on tasks they aren’t equipped to handle and use LLMs to fill the gaps quickly instead of taking time to learn (which LLMs speed up!).
This is good insight, and I think honestly a sign of a poorly managed team (not an attack on you). If devs are submitting poor quality work, with or without LLM, they should be given feedback and let go if it keeps happening. It wastes other devs' time. If there is a knowledge gap, they should be proactive in trying to fill that gap, again with or without AI, not trying to build stuff they don't understand.
In my experience, LLMs are an accelerator; it merely exacerbates what already exists. If the team has poor management or codebase has poor quality code, then LLMs just make it worse. If the team has good management and communication and the codebase is well documented and has solid patterns already (again, with or without llm), then LLMs compound that. It may still take some tweaking to make it better, but less chance of slop.
Might be true for you. But there are plenty of top tier engineers who love LLMs. So it works for some. Not for others.
And of course there are shortcuts in life. Any form of progress whether its cars, medicine, computers or the internet are all shortcuts in life. It makes life easier for a lot of people.
