Something similar was going on with cloud a few years ago. The story was if you get cloud you can get rid of those expensive infrastructure people and it will all be so much more reliable. So the big boss gets a cloud strategy and foists it on those lower down. There's also pressure to be an on-trend boss. If all the other boss' are getting into it, then you need to as well.
The bosses have seen pay and benefits go up and up and up. They've seen people jump between companies, taking institutional knowledge with them. They need the job market to crater so they can re-exert control in the relationship. LLMs are fucking catnip to this belief system. "You mean I do need to deal with those people that I have to hire and train and pay? I hate those guys! Awesome!"
