I love these kinds of retorts-to-the retorts. Let's start.
1. Yeah, he didn't miss the point though. Better weather means people take good weather for granted, and don't get all gah-gah about it. The keep working, even on sunny days. Californians on the beach? Sure, there are a few, but mostly in the dreams of people who don't live here.
2. The claim was that there are lots of better people. You're right, they aren't automatically better (did he say that?). But there certainly are a lot of great ones, who didn't get that way automatically, but did so with training and experience and exposure.
3. More options is generally not a bad thing. Someone even won a Nobel prize for showing that to be true. Who are we to argue with a Nobel prize winner?
4. Exit is an option. Again, options are good. Where did the guy say you "need" an exit to be successful? I missed that part. Oh, and speaking of prettiest girls at the dance, in Silicon Valley, well, actually, never mind, but trust me, it is just a nice part of the country.
5. Again, I missed the part where she/he said it is the "only" place where a startup can be successful. Good board members can be found anywhere, but they can be found here more often, in greater numbers, through more contacts, with a greater diversity of interests. And teleconferencing works here, too!
6. It's in the Bay Area, which is actually kind of OK in terms of attracting people. Hope the link works. To be fair, it's not a picture of Silicon Valley proper, but of the Bay Area, of which Silicon Valley is a part:
