Take a look at these CGI femmes fatales. Within fifteen years (or less), interacting with avatars of comparable resolution will probably be as commonplace as Googling. I anticipate many of us opting out of "meatspace" almost entirely in order to mingle with the "beautiful people" in myriad virtual worlds.
Ultimately, will the leisure class choose the digital hedonism of Second Life circa 2020 or brave the unwelcome reality of a disintegrating environment? I can imagine visiting the "real" world becoming something of a rebel act; users will log-in after extended stays in the non-simulated world with exotic tales to tell . . . but will we bring ourselves to believe them?
