I’m not convinced that cameras and Nextdoor are having a material impact on the vague idea of “trust between neighbors,” but I admit it’s hard to gauge because I only have my own experience, which exists on a potentially wide spectrum.
I’m barely on Nextdoor and was surprised to hear there’s apparently a pretty common use of it for public shaming. The potential for petty community conflict does seem heightened by some of these technologies.
It’s been a few years since I watched it and none of this made sense to me. Just read the Wikipedia summary for a refresher and it’s one of the most incomprehensible summaries I’ve ever read. All I can say is that I remember taking the movie at its word more or less. Interesting idea though.
