Was the same in the 1990s I'd contend. I distinctly remember talking to my dad about how the internet was going to revolutionize everything. As a teenager I was all into everything going on. His words were "This won't last they don't have enough customers and costs are too high" I'd like to give him credit for predicting this but I don't think he was alone in that realization.

This is were AI maybe today cost too high, not enough customers. Some firms will survive (Amazon/Google of the AI era) others will fold.

I think there plenty of success stories out there but there a lot of snakeoil propped up by VCs.

Who will be the pet.com of the 2020s?

Also everyone and their cab drivers have money in Nvidia right now. I think we all get hurt here.
