Somehow they've managed to map a worm's brain and upload it into a robot that now behaves like a worm. A bit creepy, but this is a pretty big step for AI.
Quote: "Take the connectome of a worm and transplant it as software in a Lego Mindstorms EV3 robot - what happens next?
It is a deep and long standing philosophical question. Are we just the sum of our neural networks. Of course, if you work in AI you take the answer mostly for granted, but until someone builds a human brain and switches it on we really don't have a concrete example of the principle in action."
