Honestly, it's because the barrier to entry is getting lower and lower. This is the same as what happened to newsletters back in the day and blogs before that. Used to be hard to get in so quality was higher but then it got so easy, that anyone could do it and the market got flooded with crap. Everyone is jumping on building with AI and launching new tools they built over the weekend, most likely they will get abandoned within a couple of months if not weeks.
