Sci fi topic: If one can easily wipe out communications or remotely take over drones, would it help to have manned communication stations to ensure friendly control over your communication system?
For interplanetary communications, would being physically closer to your drones give you the upper hand in maintaining control over them?
If drones are so vulnerable, and we imagine "terrorism" or whatever organizations are numerous, anonymous, relatively well resourced, motivated, and active, then would it make sense for anything with engines (or weapons) to be manned? Leaving only drones in stationary orbits, requiring other ships to move them.
The only instance i can think an engined drone would be acceptable would be if it were strictly AI, not remote controlled.
