We recently discovered SG1 and are going through the seasons on DVD through NetFlix. Interesting in that we've never watched a show broadcast on television. Our SG1 experience is solely on DVD, enjoying the process of going through the series chronologically from the beginning.
We recently made it to the Season Three finale "Nemesis," where the Replicators first appeared. Replicators are artificial organisms that take the form of small metallic bugs that kill and rapidly replicate. Watching them consume the natural materials of the Asgard spaceship made me think of how that image must be what it would be like in a nanobot accident, consuming our world at the molecular level.
One of my favorite books, Our Molecular Future by Douglas Mulhull, uses an example of nanotechnology saving our world through a planet-killing asteroid being "eaten" by self-assemblying nanobots. I sure hope the dang things don't eat Earth before they perfect that asteroid-eating technique.
