What is blue goo?
Blue goo is a group of nanotechnological machines that would monitor and control other machines to ensure that their replication does not get out of control. In other words, Eric Drexler’s proposed active nanotechnological shield would be blue goo. Bugs in the blue goo “operating system” could turn it into grey goo. We hope it concerns the reader that four types of “goo” have already been named yet the dangers of self-replicating nanotechnology are not a significant concern to our world leaders.
