It is amazing how natural it was for the worm to start programming the computer. The programmers did not do any external programming. The robot is controlled completely by the worm. "Of course, the brain simulation still isn’t exact - for one, the researchers had to simplify the process that triggers an artificial neuron to fire. But the fact that this robot can move, stop before it bumps into something and reverse using nothing more than a network of connections that mimic a worm’s brain, is pretty incredible."
