I think it's the exact opposite -- LLMs have revealed the precise utility of programming languages. For decades the "English as programming language" has been the holy grail of language designers. From COBOL to SQL to AppleScript, it was the hope that one day we'll be able to program a computer just as easily as we can instruct a person.

Well LLMs finally offer that, and what they are proving is what programmers have known for decades -- natural language is a terrible way to specify a program to a computer. So what is happening in the LLM world is they are reinventing programming languages and software engineering. They're just calling it "prompt engineering" and "context engineering".

What this tell us is that natural languages are not only not sufficient for the task of programming, to make them sufficient you need to bring back all the properties you lost by ditching the programming language. Things like reliability, reproducibility, determinism, unambiguity are thrown away when you use an LLM, and context engineering / prompt engineering are ways of trying to get that back. They won't work well. What you really want is a programming language.
