I'm betting it will be a mess. It's one of the reasons I have very little to do with drones.
I suspect it's only a matter of time before there is a high profile assassination or attempted assassination, and we get a knee jerk reaction and a sudden blanket ban on private drone ownership.
I know a few guys who make money with drones, and I know a couple guys who write computer programs, and the potential applications of drones is limitless. You can program a fleet of drones to do a wave attack with a small explosive and a rudimentary trigger, and it's very difficult to defend against. A single nutjob with an internet connection could figure out how to fly an FPV drone with a simple trigger into a high profile person. The Ukrainians seem to be fond of a stiff wire through a loop of wire that closes an electrical circuit when it runs into something at speed.
Apparently the coding required to launch a wave attack is quite simple and straightforward, while the programming needed to use drones defensively is much more difficult and can require some form of AI.
I should add: I've read about drone jammers recently, but I don't know anything about how they work.
