Eliezer seems to be predicting that videoconferencing will become common in the next decade. Yes, some use it now, but it is still not common. I predict that it will not become common until someone uses a utility to modify your appearance so that when you look at the eyes of the person on the screen, your image on the remote end will look like it is looking at the eyes of the person on the other end. This might well be developed in much less than 10 years, however.
