1. Saying that Boston is the center of ideas is lacking. Ideas aren't an industry, the way movies, finance, or tech is. Also, ideas are cheap. It's the vetting and execution of ideas that is valuable.
2. The quality of life issues need to be addressed. It's embarrassing that MIT students leave for Google, Facebook, etc., but I can also understand why. Aside from Kendall, the Boston area feels old, expensive, somewhat dilapidated, miserable in the winter. That's going to turn off a lot of people.
