Continuing a process that began back in the 1960s, the United States has this week taken us one step closer to a world in which Metal Gears cease to be science fiction and start being part of the military's everyday life.
Boston Dynamics, whose military robots even look like Metal Gears, this week released video of their "Cheetah", a model so named because it can run at 28.3 miles per hour. Which is faster than Usain Bolt.
I am not having nightmares about this now. They will surely come later tonight.
