I didn't see any "feeling superior" at all in what nkohari said. You don't have to feel superior to someone who is behaving childishly just because you don't want to be around them. And I don't think he was targeting "everyone there" either. He just said Silicon Valley was "full of drama and ego wars". Now, perhaps "full of" is overly strong. I'm sure there are plenty of level-headed people in the mix too. But I don't doubt from what I've read and seen that there is plenty of "drama and ego wars" to go around.
You also completely misinterpreted what I was saying, but I suspect you're not interested in that anyway.
L.A. = High school for adults
New York = College for adults
Silicon Valley = Middle school for adults
That's not meant as pure criticism, I actually kind of like it, but it just gets annoying at times.
Also, if Silicon Valley were middle school for adults, there'd be more girls here.
There really is an overwhelming aura of "you don't get taken seriously unless you're in the Valley" which gets a bit grating when you have legitimate reasons for living elsewhere.
The OP simply means that the grass isn't always greener.
