This is a very exciting technology. I work with in in the city space, creating digital twins for utilities and the like. The concern for doing this for individuals has been brought up in the other comments. There is an issue of safety and also the problems that arise amidst anonymity. The digital space separates us from reality and often people feel that it also separates them from repercussions. My hope is that advances with blockchain technology can help us pass these particular hurdles.
