I disagree, a sense of shared suffering can be really helpful in building close and meaningful friendships. Connecting with another miserable person who understood what I was going through - and plotting with them about what each of us could do to try to change things - was one of the key things in getting me through one of the most depressed periods of my life.

No book clubs or discussion groups or political action or volunteer groups? Maybe you need to move; there should be a lot more than tech going on in any decent-sized city. Even if it's such a tech-focused area that lots of the attendees happen to work in tech, you'll see other facets of them at those events; people have passions outside of their careers.
