I know, I know. I was hoping for a ninja vs. evil cyborgs too, but this is still really cool.
The youtube channel "Just Wow Me" posted this video of a master swordsman in a precise sword swinging contest against a robot that is basically just a giant rotating arm of death.
The result is pretty surprising, and the contest is interesting as hell to watch.
Skynet is coming, friends. I'd say you should keep your blades sharp, but we all know we'll need lasers at the very least. Or a kind-hearted T-800 who eventually learns why people cry.
