That, alongside the fact that his PhD thesis veers on the side of being an undergrad survey paper with very few things to offer machine learning, and alongside the fact that he tries to push association with MIT hard (despite having nothing to do with them) should tell you that Lex’s position is largely the product of nepotism and connections, and his hustle is mostly grift and hype that depends on the excellence of his peers to push his platform.
So basically, having a famous father did most of the work.
