Another aspect this is missing is that, if AI works well enough to fire people (it already does, IMO), there is a whole world of software that was previously out of reach to be built. I wouldn't build a custom photography app for a single individual, nor would I write a full POS system for 3 people bakery. The costs would be prohibitive. But if a single developer/product designer can now be up to the challenge, be it through a "tweak wordpress plugins until it works" or through more serious engineering, there is going to be a whole new industry of software jobs out there.

I know that it works because the amount of softwrae I now write for friends, family or myself has exploded. I wouldn't spend 4 weekends on a data cleanup app for my librarian friend. But I can now, in 2-3 h, get something really usable and pretty, and it's extremely rewarding.
