Couldn't agree with this more. I'm relatively young, but I'm trying to get out of tech (and especially engineering) because of the lack of a stimulating cultural environment. The kind of conversations I like having, the kind of women I'd like to meet, and the kind of company I like to keep just don't exist in tech. Talking about video games was cool in my early 20s, but I've had 30+ coworkers that literally only talked about video games and the most recent tech stack. Yuck.
Coming from having studied philosophy (at an elite school) and where most of my old classmates are lawyers now, it's kind of a bummer. As an aside, startup people/founders/investors tend to be much more eclectic, but tech, at the ground level, is an intellectual wasteland.
