Of all the people to hand-wring about, the bohemians are the last we should worry about. They will relocate, but they will be fine - and they'll bring whatever benefits they bring to areas that need them a lot more than cash-flush cities like San Francisco or Manhattan.

Not that I agree with the authors that bohemians are what make a city desirable to wealthy yuppies (like, if we're being honest, myself.) I suspect we both like the same things about higher-density cities while mutually disliking each other.
