The best programmers I know

> I'm not sure if all this advice will become irrelevant or if those programmers trained in the 2020ies will not become those "best"..

It's how they use the AI. If they see it as a glorified StackOverflow where you paste a big chunk of code and ask "why does it not work", they'll be in trouble. If they are able to narrow-down their problems to a specific context, express them well and take the output of the AI with a grain of salt, they'll be 10x programmers compared to what we were in the 2000s, for example.

You could argue that a "feature" of Stack Overflow is the culture. They're building a reference, not a help desk, so they expect questions to be original and researched. Once you're in a corporate environment, if you don't have experience in asking good questions, you'll come off as incompetent.
