There is the opportunity to do more and better if you're smaller and more nimble.

Breakthrough ideas look crazy, nuts. It’s hard to think this way — I see it in other people’s body language, and I can feel it in my own, where I sometimes feel like I don’t even care if it’s going to work, I can’t take more change. O.K., Google, O.K., Twitter—but Airbnb? People staying in each other’s houses without there being a lot of axe murders?

The multipurpose device will always fail.
