Startups long ago stopped being about building innovative business, and about VCs employing a bunch of kids to work really long hours on bad terms to make the VCs rich.
I think it is a legitimate criticism-- not ad hominem-- to say the Bay Area model has produced a bunch of soulless startups. Though of course some do follow this path and still retain their souls.
I guess I would not be so pessimistic and give founders the benefit of the doubt that they think they are building something innovative (a word that means different things to different people).
The summer YC class had a fusion startup and a fission startup if I recall correctly. That is innovation in my book. And I think most startups are trying to change the status quo even to a small extent.
And why does a startup even need to be innovative? In this great talk by the founder of Asana (http://ecorner.stanford.edu/authorMaterialInfo.html?mid=3117) the point was made that while they're not curing diseases their software helps the people that are stay organized and save time.
