>> it was by chance that in about the year 2000, i think, i wound up in the desert on a visit to yucca mountain. america's planned nuclear waste repository, 100 miles north of las vegas. a hole in the ground where ten plus billion dollars were spent on vastly expensive experiments trying to prove this place is going to be absolutely safe quote for the next 10,000 years. so it just felt like, wait a minute. this is nuts! among other things, have you even thought we are professional futurists many of us on this trip, what exactly is this world 10,000 years from now that we're trying to protect?
