Boston Dynamics’ video of a humanoid robot executing a perfect backflip sparked a lot of dark humor, and now billionaire Elon Musk has responded with dark seriousness about the risks posed by super-intelligent, super-agile bots.
Musk suggested that future robots could move so fast they could match the fictional Flash, who eludes his comic-book foes by moving too fast for the eye to see. Compared to that superpower, doing human-level backflips is “nothing,” Musk said in a tweet.
