Video: Boston Dynamics gives us a terrifying glimpse into a dystopian future where Santa's reindeer have been replaced with (highly kickable) trotting robotic dogs. In this (what's the opposite of heartwarming?) holiday video we see three of Boston Dynamic's Spot bots, the younger sibling to the company's BigDog, pulling a sleigh. If there's one silver lining, it's that Santa hasn't been replaced by ATLAS -- yet! Did Futurama teach us nothing?
