The part where the nano tech gets into the air and rain. I believe that would lead to the end of everything. All matter would be converted into "nano mites". Ive heard this called Grey theory or grey goo theory. They would continue to reproduce until there was nothing else surviving except the nano mites.
shareIf the nanites' self-replication was governed only by some bit of embedded code that said "reproduce yourself at every opportunity" then yeah, the "grey goo" scenario seems likely. But whereas the nanites seemed to be networked and under Will's control, presumably he could 'throttle' their self-replication so as not to consume every iota of material available.
I'm an island- peopled by bards, scientists, judges, soldiers, artists, scholars & warrior-poets.
It depends on what the nanites were designed to do. One practical purpose they hope to use nano-technology for is to inject them into a cancer sufferer and the nanites would hunt and kill cancerous cells. After that they just get pee-ed out.
So, if they would turn into grey goo, it wouldn't be much fun for the cancer sufferer - right?
At least someone has finally had some fun with nanotech. Michael Crichton wrote "Prey," where nanotech swarms go out and kill. But, that never made it into being a movie/TV project, probably because Crichton became such an Climate-Change denier towards the end.
