But seriously, it is ridiculous for these reporters to make such outlandish claims about nanotechnology. Its been 15 years since nanoparticle drug delivery was tested in cells, and we are just beginning phase 1 clinical trials in germany and US on magnetic nanoparticles. Regardless of the FDA implications of nanobots, the actual impact will be very small in the next 20 years, perhaps it could report of blood pressure or flow rate using RFID, but its not going to have robotic arms that will wield a sword and evicerate a cancer cell.
