I'm happy enough in academia. If I left it, it would only be for assured big bucks with job security. So, yeah, I don't think the startup life is really for me.
Academia also has wonderful vacation policies that are pretty near impossible to beat. My dad, a professor, hung out with his family for pretty much the entire duration of summer vacation. Multi-week vacations to visit extended families 400-800 miles away? Can do! Not a problem!
This is not normal for computer science academia, at least in my current department or my alma mater's. I've only met one professor who doesn't seem to work more than an average software developer.
