genetic programming combined with neural networks is fascinating, and a great way to solve problems as it will usually find the best solution given enough time and power. It is indeed cribbed straight out scientific evolution with DNA mutations and adaptations, and modeling what we know of brains, applied to natural problems it often converges to the exact same solutions as nature.
The frightening thing about these robot companies is they all pretend a human is in control, when in fact they will admit we are a burden on the system and they would be better off without us involved.
If you want to know WTF Google is doing in robotics, I suggest you go ask Lt. Cmdr. Data, his head will be down in a mine near San Franscisco for the next few centuries.
