Agree with above, Sama puts himself into same bucket of people as Zuck and Musk in how to build future series. What he has build so far ? Happened to be a VC partner sitting on huge pile of cash, distributing it to bunch of YC applicants ? I could see Paul Graham as YC founder takes some credit for creating all YC unicorns, Sam is just one of many partners in VC firm, nothing outstanding though.
