Oh no, its a machine that makes loud noises and moves around! Truly the end of the world is nigh! Do you cower in fear when you hear a vacuum cleaner too?

That and how weirdly it moves. It's just bizarre how perfectly good it is at rebalancing itself. That and how they walk in general is just... haunting. For some reason. Uncanny valley, maybe?
