I think it would be better if there were fewer grand claims about how AI is going to revolutionize research and more people trying to make the best use of AI to improve their research, and let’s see what we get.

Bubbles keep appearing when new technologies emerge (cup.columbia.edu/book/specul…). Too much uncertainty about future profits leads investors to make early bets on individual ventures.
Why do industries keep falling into "overbuilding bubbles"? Telcos digging fibre in the late 90s, railroads in the 19th century, AI today. Why do firms overinvest in capacity they will later struggle to scale back? Surely somebody has written a model for this?
