Worth noting that Stockfish is actually the only engine that hasn't lost a game. The lackluster performance is it just not beating the weaker engines, something that Komodo and Houdini have done (but they have also lost against stronger engines).
Funnily enough, I feel there's a lesson for startup people in this. I have seen many people (myself included) talk themselves out of big, bold bets just because they are very good at thinking up reasons something should never work.
