I've just read "Artificial neural networks are more similar to the brain than they get credit for"

Such a great article that compares Deep Neural Networks with our brains.

The largest deep neural networks are composed of a few billion parameters. The human brain, in contrast, is constituted of approximately 1,000 trillion synapses, the biological equivalent of ANN parameters. Moreover, the brain is a highly parallel system, which makes it very hard to compare its functionality to that of ANNs.
