I don't know... This guy has made some pretty incredulous and far out predictions before this one.
I've heard that in 1998 he proclaimed, "Computers will one day be very small, and very fast". And, just a few months ago he was saying something like, "Renewable resources are the future of energy production".
Seems pretty outlandish to me.
Are you being sarcastic or serious? Because in 2013 we have hand held computers that are screamingly fast compared to household computers in 1998 - they're called smartphones. And renewable resources are the future of energy production, especially solar and wind energies.
