He has an incredibly story (coming from nothing) but lets look at his career:
He "leaves" (aka fired) Facebook for being a D*ck head. Nobody is willing to work with him because he is rude and a jerk. His direct reports would cry regularly. Steven Levy talked about this in his book on Facebook.
He starts a VC fund. The fund has no "major" wins. For a guy writing checks in 2011 he didn't get any of the big wins. The VC fund literally "burns down" as Axios put it because he divorced his wife and was chasing a girl in Italy rather than being in the office.
Now he SPACs worthless companies selling them off to retail traders who think he is Warren Buffett. He is a salesman. The guy is on CNBC every other day.
I get the "holding truth to power" narrative is attractive but Chamath is not our saviour. I would argue he is just as bad as any other hedge fund manager. Taking advantage of retail investors.
Chamath talking about protecting the little guy is like Steve Cohen talking about respecting securities laws.
