I can't and won't argue that AI is currently overhyped and that there are people whose lives are miserable because they're being forced to use bad AI implementations.
However, I see a lot of people around me who pay for LLMs from their own pocket when their employer won't foot the bill for them. And if it's their own money at stake, you can be pretty sure that they see some ROI there.
That is only true for employees, ignoring anything but work circumstances and also reducing returns purely to take home salary. I've personally saved a lot of time because of LLMs already, and that's worth quite a lot to me.
