If Bill Joy's concerns are justified (i.e. not in the dino-killer
asteroid strike to Tunguska Event range of probability) then I would
advocate that nano should only be tested OFF earth. On that basis,
colonizing the moon and mars in order to build nanotech development
infrastructure is of paramount importance and totally justifies the
investment. The potential benefits of nanotech are too great to not
develop it.
