Woohoo.
Can we print a plague nanobot?
“Can we print a plague nanobot?”
Not yet. The only defense that I see is to have the technology so widely spread that defenses against it are developed along with the technology, much like we have seen with the Internet and computer viruses.
The real danger is if the technology is suppressed except for a few governments who develope it in secret. Then the danger would be a breakthrough in one country that would give it an advantage over all others that would be insurmountable.
Pure speculation right now.
