The argument is that humankind in general isn't ready for its' own machinations.

The dangers are there…out of all the people who would actually have hands on access to the technology in a nanotech world, the only people who have the potential of creating a grey goo scenario is the pathetic military. Which is why, I believe, the military should keeps its nose out of something it will never have the capacity to understand in the first place.

Nanotech should be for everyone – but anyone who uses the technology for warfare should be eliminated – the technology is just too dangerous for simpleton politicians who are trigger happy.
