A rogue comet causes every machine on the planet to revolt against Mankind. ATMs can only display insulting messages, but tractor-trailers are capable of doing a lot more than calling surprised bank customers bad names.
I would much rather run into a murderous can opener than a psychopathic self-propelled lawnmower, while any variety of mobile woodchipper means that my butt would be heading for the closest vertical rock formation. Granted, once I climbed to the top of that, my next problem might well be a swarm of RC helicopters. I’d still rather my last moments recreate the epic finale of “King Kong,” vice a random scene from “Woodchipper Massacre.”
Whoever said that the pen was mightier than the sword was never on the wrong end of a machinegun.
