Is this really any different than the problem in software engineering - where AI is doing the work of junior programmers and now they aren't getting the development they need?

Seems the same to me. And it'll be the same in all industries soon enough. And then it won't just be the junior people.

All the same problem: what do people do now?

It’s better to compare this to computer science, especially, theoretical one. LLMs stop people from exploring new languages, architectures and so on.
