Looking at the Russo/Ukrainian war, I wonder if/when someone introduces "owl drones".
Current drones are not very loud (well, Shaheds are), but if someone could make them more silent, they would be even harder to detect. Maybe covering them with a structure similar to owl featchers would do it.
Zipline has a patent on their quieter drone rotors, based off barn owls, according to Mark Rober.
