I just watched part of "Rage Against the Machines" on the SciFi channel. It's a "documentary" that highlights everything we should all be very afraid of -- including, of course, nanotechnology.
In the world of this documentary, it's a foregone conclusion that out-of-control nanobots will destroy the world outside either before or after they consume our flesh from the inside.
What I found particularly amusing was an interview with nanotech scientist Rick Smalley in which he describes what a self-replicating nanobot would do. I can only guess that this interview snippet was taken out of context since, as many nanotech followers know, Smalley believes such a self-replicating nanobot is the stuff of dreams and nightmares.
