When the "boring" parts of programming can be automated, so can the "fun" parts, and AI will have "taken our jobs" just like they did down at the toothpaste factory. I'm not concerned about that. When it happens, that's fine by me. I have other skills to fall back on.

It won't happen all at once. There will be a long process of elimination of more and more layers, leaving more and more developers available for the work on the less automatable (more fuzzy and chaotic) side of spectrum. It will take years. At the end all of them will go home and do something else, of course.
