Speaking at a gathering of young entrepreneurs a few years ago, Mark Zuckerberg surprised some in the audience by saying that if he could do it all over again, he would have stayed in Boston and founded Facebook there, not in Silicon Valley. “There’s a culture out here where people don’t commit to doing things, I feel like a lot of companies built outside of Silicon Valley seem to be focused on a longer-term,” he said. “You don’t have to move out here to do this.”
