Part 6/11:
The conversation also critiques the fanciful notion of nanomachines—tiny robots capable of manipulating individual atoms. This line of inquiry raises significant concern over potential ramifications, notably the so-called "Grey Goo" scenario, wherein these machines could spiral out of control. Ensuing debates—such as the notable Drexler-Smalley debate on the viability of nanoscale technology—present hurdles to achieving precision and efficiency, particularly in self-replication.
