No, it's not. First, most "big tech" aren't nerds in the sense you mean, and they act more like the "cool kids" bullies in those movies than nerds. Second, the negative sentiment has more to do with wealth inequality and all that brings than any such petty rivalry as you describe.

Also to be quite honest software engineers aren't as smart or nerdy as they think they are in general. Very arrogant and egotistical, though, for sure.

I believe the primary reason for anti-tech sentiment in SF is gentrification: https://en.m.wikipedia.org/wiki/Gentrification_of_San_Franci...
