A really good essay about the status quo of Silicon Valley and the tech industry in San Francisco:

It suddenly occurred to me that the hottest tech start-ups are solving all the problems of being twenty years old, with cash on hand, because that’s who thinks them up.

It strikes me as a bit of a contradiction that in the 21st century all these companies are trying to centralize efforts and move as much employees as possible to their headquarters. Why do not make use of the very same innovations that they are bringing to market, embrace diversity and keep employees in different countries?
