Terminator is a good movie but in reality, a cheap autonomous drone would mess one of those up pretty good.
I've seen some of the footage from Ukraine, drones are deadly, efficient, they are terrifying on the battlefield. Even though those robots will get crazy maneuverable, it's going to be pretty hard to out run an exploding drone.
Maybe the Terminators will have shotguns, but I could imagine 5 drones per terminator being a pretty easy to achieve considering they will be built by other autonomous robots.
