Yes, I guess in the future a lot pf people will be killed by autonomous swarms of drones that just don't like the way they look, sometimes malfunction, give plausible deniability for war crimes, etc... ("who knows what the drones did, there was no communication. Also, the drones cannot possibly kill anyone who isn't a terrorist. Also, surely it was the drones of the other side.)

That's actually a great example for something I'd like to be banned. It would require international cooperation and arms control agreements, which unfortunately currently doesn't seem likely to happen.
