I would argue that just because they want to work on AI while it has a lot of hype, might not be a good thing. Folks should do what they are passionate about and interested in, not just raise money to turn a fume from the karat and greatest buzzword technology. Will they leave AI if the tides change?
I'm working on an idea that I'm submitting to YC this year. AI is revolutionizing the field I'm most passionate about, I feel like it would be a waste if I didn't even try to make a contribution at what's possibly the last time we get to make a significant contribution in this way.
I was hyped about Bitcoin when it came out, but the only truly revolutionary thing that happened after Bitcoin in that field was Ethereum, and there really wasn't anything to be hyped about besides that in the decade since even though people kept hyping it.
This hype is so different, it's as powerful as web 2.0 was. I felt like I missed out on building something epic then, and now I get another shot so I'm not gonna miss it. I bet there's thousands of people who feel this way.
