If you're not experiencing variety of culture and thought in New York City then, frankly, you're doing something very wrong. The OP's statement wasn't limited to software developers, who I agree still tend to be a relatively homogenous group even in NYC. But you really ought to stop outside your professional circle once in a while. If you go to a bar in SV it's nothing but people in tech, talking about tech. If you go to a bar in NYC you don't see it anywhere near as much.
