It'd be great if: A, he could show a demo of what he means. Like what kind of features were do much easier to make and B, what's YC show? Certainly they have tons of data, and simply knowing the basic tech choices of all those companies would say something. Were people using better languages more successful? Did they, I dunno, have a higher demo day ratio? Seems a waste to not look at those things. (My guess: it is probably totally outweighed by luck, assuming better languages users are as driven as, say, JS or PHP users.)
