Let me give you a technical parallel. A couple of engineers/architects from Big Co. that's hugely successful leave and go to Hot Startup. There they proselytize their One True Way because honestly that's all they know. Everybody in Hot Startup goes along with it because they are Senior Engineers from Big Co. who are now plotting the course and Big Co. is HUGE so they know what they're talking about. Now because Hot Startup is suddenly using the One True Way everybody else in the market tries to copy them because that's obviously why Hot Startup is Hot. This leads to a job market where people optimize for things used by Hot Startup. This tilts the skill set of the general tech market towards the One True Way making it gospel to a lot of people. So hiring managers who don't know the first about anything suddenly start optimizing for One True techs and ask for 20 years experience with React. They think they're doing the safe thing by using the same tech stack used by everybody else - the industry standard. Never mind that the "industry standard" changes every time it's convenient.
This is the same thing for CEOs. Oh you're having a slightly down quarter and have to answer to investors? Say you're using AI. That's the in-thing and will give you that bump to ride out the quarter. You screwed up in 2021-22 and hired a fuckton of people who are just sitting on their hands costing the company money? Say AI and get rid of them because they're not productive. It's got nothing to do with collusion or anything like that. It's just that people have mismatched expectations and things happen downstream of these unmanaged expectations.
