Sure. I mean perhaps, LLMs will accelerate a return to a more medieval culture in tech where you "have to start at 12 to be any good". Personally, I think that's a good (enough) idea. By 22, I'd at least a decade of experience; my first job at 20 was as a contractor for a major national/multinational.

Programming is a craft, and just like any other, the best time to learn it is when it's free to learn.
