Can someone explain to me why this guy opinions get attention? Did he invent something? Build a business? Have a rich intellectual career? Made a killing in the stock market?

I am not being sarcastic, because he really sounds like an idiot for tons of stuff he spews out, perhaps everything. Reminds me of propaganda tv hosts in the Middle East - no expertise in anything but full of “wisdom” providing cope for the ruling class.

Why is he famous?
