There's a well-trod path to success for tech VCs over the past 20 years. Increase your profile online. By virtue of your influence, every investment you touch and pump has instant buzz (for an example, look at the latest fad - Clubhouse). This boosts user numbers and valuations. Pump, pump, pump, and then sell to your adoring followers.
Chamath is playing this to a T. I think he's obviously a smart guy, and I feel like if he's not aware of the damage his pumping is doing to the small investor, one day he will regret it. If he wants to address inequality, the way to do it isn't to lead novice investors into overhyped garbage like Virgin Galactic and pure speculations like Bitcoin.
