Episode Details

Art Bell interviews technologist and author Mark Pesce about the rapidly approaching nanotechnology revolution and its potential to reshape civilization within a generation. Pesce explains that molecular-scale machines could eliminate disease, end hunger by converting raw soil into food, and extend human lifespans. He describes how nanobots built from atomic-level components would operate like miniature mechanical computers, millions of times faster than anything available today, with functional prototypes expected within a decade.

The conversation turns to the darker possibilities, including the notorious "grey goo" scenario in which self-replicating nanobots consume all matter on Earth's surface within approximately 48 hours. Pesce reveals that nanotechnology researchers discuss this threat privately but downplay it publicly to avoid alarming the public. He notes that the basic tools for nanotechnology are relatively inexpensive, meaning even individuals working from home could eventually build dangerous devices.

Pesce also explores how nanotechnology will blur the line between physical reality and simulation, noting that video game graphics are improving at eight times the rate of Moore's Law. He warns that military applications, genome-targeted weapons, and the displacement of entire economic systems built on material scarcity represent challenges that current social evolution may not be prepared to handle.
