Besides, Grey Goo is more likely to be born by accident, not made. If you have problems with alpha hits in microtechnology, what do you think radiation will do to nanotechnology? You're gonna knock off the control system for some gadget before it's even out of the lab. This stuff makes biowarfare research look like a Thomas Salter chemistry set.
