It’s quite impressive how it’s possible for us to simulate cognition using software. Actually, can it even be called a simulation? Aren’t these machines learning exactly the same way that we, as humans, do? Well, beats me. But it makes you think, because it might happen that the things that mark the difference between computers and living beings might just disappear one day.

From the video description:
"Cornell University professor Hod Lipson demonstrates how a robot can teach itself to walk without any knowledge of its form and function.  ‘Within a relatively small number of these babbling actions, it will figure out what it looks like’, Lipson says. He adds that eventually ‘it can figure out how to move.’"
