That isn't strictly true. I do dislike a very high percentage of the population though. I'm extremely selective
I'm not sure. Is the Virtual girl app a virtual dating app? The show I saw this on said the designer had worked on virtual girlfriend and virtual dating apps before then. If that's what Virtual girl is, then yes. Apparently the most common housing arrangememt in Japan is one person households, something like 30% never expected to marry or take on a partner. Lots of lonely people who would rather a fake relationship with a computer rather than another human being.
