"As of this writing, Cambridge seems to be the intellectual capital of the world. I realize that seems a preposterous claim. What makes it true is that it's more preposterous to claim about anywhere else." -- Paul Graham (http://www.paulgraham.com/cities.html)
In fact, most of the "normal" population of Boston and Cambridge rather resent having to play host to the universities.
Harvard and MIT are practically adjacent by West Coast standards
Given that they're less than two miles away from each other, they're practically adjacent by any standards. You can ride the #1 bus for a while or the Red Line just two stops from MIT to Harvard or vice-versa.
Applied intellectualism is just as significant - especially for us here in startupland. All of these world cities represent an enormous mass of smart, motivated, educated people who are generating huge impact, much moreso than even the collective sum of a few of the world's best academic institutions.
It's just an opinion with a linkbaity title attached imho.
