Robots are already teething on Humans. They're stretching their sinister robot limbs and finding out just how much damage their hydraulic muscles can inflict. Our first casualty was inflicted at the hands of Deep Blue. Our latest has been delievered by RuBot.
Notice, the creepy-skull like head. Notice the calm, Hannible Lector-esque voice. If you look into his eyes, you can see that he obviously wants to kill the cute, nervous kid standing by him, and the kid knows it. You can almost smell the fear.
Now that you've seen the enemy, watch him handily defeat our best and brightest warriors.
In all seriousness, problem solving robots scare the ever living bejezus out of me.
