This is a huge part of why I didn't enjoy being in SF (admittedly for a very short few months).
Every party I went to, most conversations I had (or overheard in a coffee shop) were tech-related. It felt impossible to have a conversation about anything else, and all conversations naturally gravitated towards tech like some sort of awful singularity.
It's pretty refreshing regularly talking to people who work in the arts, finance, education, administration, etc. If nothing else, just for novelty's sake - more interesting conversations happen when you can't talk about your work all the time.
