We can kill robots without remorse, and they're likely going to be worse than a human agent at most things for a few years. Not a bad timeline for them to waste their time on.
As insane as American politics is "I can blast robots on my property" has exactly the right amount of crank appeal to be possibly the final 90/10 issue
What if they're private property though? Historically, the state has always valued private property over human lives, so the response could be even more brutal.
Except we're the ones that pay for robots, and the cleanup and the settlements.
