> Imagine pitting neural networks in an adversarial environment (just like the real world). Under competitive pressure for limited food (computation resources), evolved neural network could start approaching optimal architectures that do the job but have no superfluous, pre-conceived notions of the (modeled) world.

Sounds almost like these robots [0], which learned to lie to each other. They didn't use a neural net, though.
