Dr. Alan Goldstein explains how the leading artificial life researchers are creating a huge hazard by failing to understand the role of chemistry in molecular engineering and manufacturing, aka, nanotechnology. He says the aliens will not arrive from space, but rather, from our own labs, and that by not understanding this clearly, we put humanity itself at risk.

The Lifeboat Foundation is sponsoring Goldstein’s initiative for raising awareness about nonbiological replicators - the A-Prize. Listen to a separate mp3 interview about the A-Prize here.
