1) For an astronomer like myself, this is kind of exciting. If they replace them in the future, hopefully they do so with directional lighting, which is much more efficient than the usual spherical emitter nonsense.
2) I live a few hours from Detroit. Having visited different parts of the city several times, I can say that the perspective held by inexplicably angry people on the internet isn't very accurate. Yes, Detroit is a troubled city, but it's absolutely recognizable as an American urban center. There are very nice parts, very bad parts, and in between parts. The balance between those is weighted more heavily toward the very bad than in a city like, say, New York or San Francisco, but they still clearly face the same issues and have the roughly the same responses.
