We are at a time where the Internet is changing the world in significant ways, and the biggest changes I expect haven't fully come to fruition yet. They are forged in the minds and the blood sweat and tears of lots of startups, including the ones that you just dismissed carte blanche.
YC has created tremendous value, as have many other startups that you personally probably would never use or care about. So rather than sound the misguided cry of "where's the innovation?", perhaps it would be better to look within oneself and find the fire to create it yourself.
