As far as I am concerned he lucked out because someone got him into MIT and he lucked out the second time because he got on the Joe Rogan podcast. The rest is history. But I was just amazed how dumb the man sounds on his own podcast and the quality of guests he gets.
I'll be honest, I am probably jealous, but damn, I almost think like his podcast has negative value. Every time his guests speaks I get smarter, every time he speaks I just get angry that someone this dumb got this lucky.
Edit: Typo + It turns out that Lex actually has a PhD from Drexel University, not MIT, as pointed out by slater.
