This is one of the problems with a lot of the data in this area. So many different things were/are happening in the space. Gold rush because tech is profitable including bootcamps, AI and companies planning for AI in the future, interest rates/overhiring, etc. etc.

That said, I find a lot of anecdotal information from many people in the space that tech was flooded by a lot of junior programmers who were basically in it for the money with minimal training and they're having a hard time of it. The same thing happened to webdev during dotcom.
