Human beings don't live in reality they live in their imaginations work to bring that imagination into the real world through technology. History is just that history, we never had this sort of tech so looking to history and saying it won't work is irrelevant. Basic psychology is that humans don't live in the real world but in their imaginations. There is already a subsection of society that's already so involved in gaming that they don't care about the "real" world any more, links on the edit above.
