Brains do not actually work very similarly to artificial neural networks. The connectionist approach is no longer favored, and human brains are not arranged in regular grids of fully interconnected layers. ANNs were inspired by how people thought the brain worked more than 50 years ago. Of course, ANNs are meant to work and solve practical problems with the technology we have. They're not simulations.
