I have the same reaction. Also, there's definitely a local optimum for being surrounded by people who are all trying to hock their crazy "world-changing" dreams at the same time.
A population of 10% crazy dreamers is inspiring. A population of 90% crazy dreamers is maybe inspiring in limited doses. Being surrounded by that kind of person, every day, all the time, is tedious and uninspiring. I can see how it's great for investors (who only really care about that 1 success in 100), but for the other 99 people involved, it's enough to make you very cynical.
