He built the ultimate machine to attract conformists who want to get another badge. First the conformists will push out individualists by their sheer bulk and better ability to navigate the approval process. (It's their core competency in life!)
Y Combinator is a plant that has grown too large for its pot. Someday something is going to go wrong, there are so many people going through it that sooner or later there is going to be a scandal.
