A bunch of rich guy’s money going to other people, enriching some of the recipients, in hopes of making the rich guy even richer? And the point of AI is to eliminate jobs that cost rich people money?
Heck, just paying the salaries of people working in those fields. Sure, spending money stimulates the economy so I wouldn't go so far as to say it's totally wasted, it's definitely being put to a much better use than just sitting in someone's bank account. But it could be put to a lot better uses. The software engineers could be developing a new program for balancing energy loads, or managing the maintenance of wind turbine fields. The hardware engineers could be optimizing a better autoclave or building a machine that automatically dispenses medicine when fed a script. The PMs could be managing a team distributing aid in Ukraine or designing a new blood drive initiative. Jobs that have positive societal impact, instead of - at best - neutral societal impact.
