digital weapons are just compact versions of devices.
To clarify- nanotechnology as I am meaning it is the technology of building microscopic machines that can work in concert to manipulate matter on a molecular or even atomic scale. building something (or taking it apart) atom by atom. Sending tiny attack drones to target and destroy cancer cells, ect.
Doesn't that defy science on a very basic level? I mean, what would you even build them out of? Steel at an atomic level is just ... atoms, right?
