It's interesting how Alexis talks about the importance of the possibility to "stay home and do great things" for some people. Well, sounds right but isn't startup a thing that's all about change - including lifestyle? Isn't it possible to have some valuable insights when you leave your comfort zone and go some place you didn't know before? I'd rather advice Silicon Valley guys just try and leave their cozy warm place…
in a way, it's in line with your desire to advise SV guys to leave their cozy warm place. You may feel "safe" going to the valley, but you can (potentially) achieve just as much breaking ground in a different locale.
