Is this the Bay Area population of HN expressing their frustration that there are many homeless people in SF? These posts come up from time to time. I was there some 4 years ago, and I met some homeless folks for sure, but the city was nice.
That said, what did strike me as a little odd were a lot of comments on the Vision Pro threads about where if you walk around with it on outside, you'll be instantly mugged. That's just... not the case where I live in my Indiana suburb. I leave my front door unlocked, and have had no issues leaving my laptop visible on the seat of my locked car when I'm out and about. People here seem to take for granted some amount of low level violence and theft as normal, which shocks me. I don't know if comments like those come from Bay Area residents, but I sort of assumed so because I've thought that's where the user base here skews.
