I have not heard even the most enthusiastic AI booster describe net job creation as a possible outcome. If you have any details on that prediction, I'd be interested to hear what they are.
Net job creation will be the outcome as the insane number of businesses that were once too expensive to start due to lack of knowledge labor suddenly come online.
I mean... you can't think of any ways that AI could actually generate new value? Or more abstractly, of a way that Jevons' paradox can't apply in the case of AI?
After all, Gutenberg had only a modest goal of printing and selling indulgences. He didn't understand what the printing press was good for, either.
Pretty much all the jobs today did not exist before the printing press that enabled them.
