I’m a bit of two minds about this. Obviously jamming resistant high bandwidth communication enables some scarry possibilities.
But the lack of it is what drives and will drive militaries around the world to put more and more autonomy into weapons. It doesn’t matter what kind of treaties we write on paper to prohibit technologies. During a war if your drones/loitering munition are less effective than those of your enemies because your control signals are jammed you will give in and make your weapons find their target without that control signal. That leads to an arm race of ever more sophisticated autonomous weapons. That is scarry for many reasons, and probably a worse outcome for all of us.
On the other hand if communication is possible that puts a leash on this dynamic and ensurers that a human mind can remain in the loop. So… maybe being better at jamming resistant communication is actually better for humankind?
