I don't quite see how people being interesting relates to the thread. I said that forced dinners with strangers is bad, in response to a comment that said it's good. You then responded saying people are interesting. My comment about utopianism isn't that I think it's utopian to believe people are interesting, it's that I think it's utopian to believe that forcing strangers to interact is necessarily constructive.

As to your point itself, I would say I find most people painfully uninteresting. I once read that humans are generally interested in people or objects, and I'm much more interested in objects. This has naturally developed into life choices that minimize my interaction with people (besides loved ones) like working in software and having interests I can pursue by myself (rock climbing, studying languages, lifting weights). My mid-term life goal is to buy a remote-ish house in a low-population density state with multiple acres and work remotely so I can ideally go days without seeing another human. My dream would be to own and live in the middle of a forest or on a mountain so I could go weeks or months without seeing another human (again, besides my loved ones). If you're the opposite, then I agree we're just different and I hope you're able to achieve your version of an ideal lifestyle.
