I've AI divided into 3 types. After Snowden, I conjecture an AI can amass a military win by hacking. Type 2 is able to enact the standard futurist conjecture of seed-AI where it makes better hardware and software. Type 3 is smart enough to attempt attack like synthetic AI and mantle replicators that might be tough to defend against even next century. Much of the discussion is classified. For example, homes of the future with engineering books will require acoustic robot sensors. The easiest #1 attack appears to be to launch a rocket to space. Similar is to hack NASA space assets. The idea being to blot out the Sun, or hit us with a rock, or just come back from the Oort cloud with a superior fleet.
For this reason NASA's interconnectivity should be cancelled. Fibre optics are harder to hack, especially with a new coating. The best optical computer appears to use a phase change wafer as the switch; plastic holographic memory is cheaper but glass is better. Eventually you'd have all PLCs made optical but at first basic controls like ventilation fans and on-off engines would be easier.
VTOL aircraft mitigate a first strike. Rail guns and lasers are all useful munitions. Bad weather makes GEO lasers, balloon lasers, captured ice NEO lasers, L-point and Lunar lasers necessary. A safe lunar bunker of spaceships can reinforce airforces; it may be necessary to keep NPP in reserve here.
I see electric ships with a VTOL fighter jet travelling between dielectric elastomer wave power floating islands. Entangled microwaves sent from aircraft can look for bunkers. Jeep's Hurricane protoype is able to mount a rail gun and swivel to track a robot. First responders will need vehicles able to find and kill robots and climb over cars before military assistance arrives. Neuro imaging will be able to pick and pick off leaders who aren't rational and honourable.
3d printing shouldn't be in space. Neither should assembly wires, or Robonaut 2. NASA will need a rotating (two crafts tethered) space station at Earth gravity and with enough reality programming interior content and neuro imaging to keep astronauts sane enough to staff Lunar lasers with the right stuff. Displays will need to be now light pipe, and soon head mounted and directional holographic, to avoid fly-spy hacking. Neuro-imaging will ensure the internet is used by good humans. Fibre-optics or quantum ghost imaging needs to be used around critical infrastructures. Robots should not have hands. Robotics, materials science and AI researchers may already be tracked.
