Samsung have recently been demonstrating something called Ballie, which is basically a ball that follows you around and controls your entire home.
Any ball that follows me around will be tripped over in short order, whereupon I’ll probably break my neck. Hence it’s a killer robot. It’s quite clever actually because we all expect killer robots to look like a T-800 and speak with an Austrian accent. Nobody expects an invasion of killer balls.
I dread to think what my cat would think of such a thing.
Anyway, watch the video and be either suitably impressed or extremely scared as you choose.
