Does a place need to be a mirror-image of Silicon Valley in order to have some successful startups based there? I see no reason why the proportion of programmers who are inclined toward drugs wouldn't be comparable to the proportion of programmers who are inclined to avoid drugs. The latter group may prefer a country like Singapore. I don't think Silicon Valley culture is the only culture that can facilitate startups.
