Nano proponents square off against specter of "gray goo"
(Nanotechnology pioneer K. Eric) Drexler suggests that self-replication isn't the way nanomachines will be built as the science advances.
Microfactories will create nanomachines more efficiently decades from now, he says, and we can pull the plug on those. "Talk of runaway self-replicating machines, or gray goo, spurred fears that have hampered rational public debate about nanotechnology," Drexler says.
