For me that turning point was 10-15 years ago.
I guess it was slow-boiling, but somewhere between 2010-2015 was the turning point.
It got dominated by brogrammers who judged you by whether you used vim or not, teams of 20 people producing the same output as a team of two, designers doing mockups for absolutely everything and trying to boss the programmers, product managers making mountains of useless documents for everything and trying to boss the programmers, some rando had Scrummaster certification (who doesn't) and wanted to boss the programmers.
It was also when everyone started copying Google and Spotify and etc and a meeting was required for every decision, RFCs or other documents that would be produced but wouldn't survive reality, the software would have more trackers than features, and subscription was the default software model.
People keep saying "you only need 1 or 2 people to make a product now".
Well that was already the reality for me from 2000-2016.
