I'm by no means a Co-GM or anything of the sorts. So don't take my word for it but:

AIs are being developted and somewhat used. SkyGuard has some high-grade tactical AIs. The TPT develop AIs if I recall correctly. And my faction will probably create a robot army of multiple AIs working together (think of Mass Effect's Geth or Battlestar Galactica's Cylons. My guess is that basic AIs are being used, but more advanced AIs are probably only found in SkyGuard (and i believe there is 1 rogue AI among one of the factions).

For the nanobots: I believe that the FBM had something called a nanite rifle that could eath away armor but not flesh. So my guess is that they're around for basic tasks (like eating away a tank armor or preventing blood clotting) but nothing more.

Again, I could be wrong about all this stuff.
