The article starts with a philosophically bad analogy in my opinion. C-> Java != Java -> LLM because the intermediate product (the code) changed its form with previous transitions. LLMs still produce the same intermediate product. I expanded on this in a post a couple months back:
https://www.observationalhazard.com/2025/12/c-java-java-llm....
"The intermediate product is the source code itself. The intermediate goal of a software development project is to produce robust maintainable source code. The end product is to produce a binary. New programming languages changed the intermediate product. When a team changed from using assembly, to C, to Java, it drastically changed its intermediate product. That came with new tools built around different language ecosystems and different programming paradigms and philosophies. Which in turn came with new ways of refactoring, thinking about software architecture, and working together.
LLMs don’t do that in the same way. The intermediate product of LLMs is still the Java or C or Rust or Python that came before them. English is not the intermediate product, as much as some may say it is. You don’t go prompt->binary. You still go prompt->source code->changes to source code from hand editing or further prompts->binary. It’s a distinction that matters.
Until LLMs are fully autonomous with virtually no human guidance or oversight, source code in existing languages will continue to be the intermediate product. And that means many of the ways that we work together will continue to be the same (how we architect source code, store and review it, collaborate on it, refactor it, etc.) in a way that it wasn’t with prior transitions. These processes are just supercharged and easier because the LLM is supporting us or doing much of the work for us."
I think that we can already experience a revolution with LLMs that are not fully autonomous. The potential is that an engineering-like approach to a prompt flow can allow you to design and review (not write) a lot more code than before. Though you're 100% correct that the analogy doesn't strictly hold until we can stop looking at the code in the same way that a js dev doesn't look at what the interpreter is emitting.
What would you say if someone has a project written in, let's say, PureScript and then they use a Java backend to generate/overwrite and also version control Java code. If they claim that this would be a Java project, you would probably disagree right? Seems to me that LLMs are the same thing, that is, if you also store the prompt and everything else to reproduce the same code generation process. Since LLMs can be made deterministic, I don't see why that wouldn't be possible.
PureScript is a programming language. English is not. A better analogy would be what would you say about someone who uses a No Code solution that behind the scenes writes Java. I would say that's a much better analogy. NoCode -> Java is similar to LLM -> Java.
I'm not debating whether LLMs are amazing tools or whether they change programming. Clearly both are true. I'm debating whether people are using accurate analogies.

Why can’t English be a programming language? You would absolutely be able to describe a program in English well enough that it would unambiguously be able to instruct a person on the exact program to write. If it can do that, why couldn’t it be used to tell a computer exactly what program to write?

A determinisitic prompt + seed used to generate an output is interesting as a way to deterministically record entirely how code came about, but it's also not a thing people are actually doing. Right now, everyone is slinging around LLM outputs without any trying to be reproducible; no seed, nothing. What you've described and what the article describe are very different.
Yes, you are right. I was mostly speaking in theoretical terms - currently people don't work like that. And you would also have to use the same trained LLM of course, so using a third party provider probably doesn't give that guarantee.
But it would be possible in theory.
