Stanford dropout, a major failed startup, pretty much kinda "failed" into the position he is in today.
He doesn't add value at all.
Edit: This was flagged as "a personal attack" apparently.
If you add up all of the successful YC companies since he started leading YC, it's a pretty breathtaking number (the count, the valuations, and the value created). YC was having pretty serious scaling problems when he took the reins-- from my understanding, he resolved those pretty effectively. YC's growth since he's been leading it (in a lot of directions) has been impressive-- full-stop.
Edit: it looks like we've warned you repeatedly about making personal attacks in the past. That is the sort of thing we ban accounts for doing repeatedly, so please don't.
We're allowed to disagree with Altman, even on HN.
(It's also obviously wrong, since there's no way Sam would be running YC after 4 years if it were true. But we don't moderate people for being wrong, only for breaking the site guidelines. Please (re-)read them at https://news.ycombinator.com/newsguidelines.html.)
