>there are limitations to the current cartoonish representations of neural networks

How? on a broad level Deep Learning is the same as natural neural network. Signal in and then neuron decides to fire a signal out. The algorithms inside is what differentiates a human from a machine. As long as the algorithm can make intelligent decisions who cares how the human algorithm works. We are not trying to build a human brain, we are trying to build a better than human brain
