I'm happy as the next person to eye roll a lot of the stuff that gets funded but the world is just fundamentally different compared to 2000. The average time an internet user spent online at home was ~3 hours in 2000 and is about 18 now.[0] People are just so much more willing, and able, to spend time and money online now days I would be surprised if there was 2000 style crash.
