Accidental grey goo doesn’t seem plausible, and purposeful destructive use of nanotech doesn’t necessarily fall in that category. We can have nanomachines that act as bioweapons, infecting people and killing them.
Are you disagreeing with something I said? I’m not sure nanotech would be better at killing that way than a designer virus, which should be a lot easier and cheaper (possibly even when accounting for the need to find a way to prevent it from spreading to your own side, if that’s necessary). Nanotech might be able to do things that a virus can’t, but that would be the sort of thing I mentioned. Anyway I don’t see how we could effectively spend money now to prevent either.

I agree with this. I disagree that there are no clear non-goo extinction risks associated with nano, and gave an example of one.
