"able to learn more complex tasks (XOR, nonlinear regression), fast, low-power, scalable analog system... like the brain, components evolve on own based on local rules without knowledge of larger structure... tolerant to errors, robust to being made different ways, scalable... interfaces with cameras, microphones collecting data requiring processing... simpler, well-understood dynamics, trainable, uses simple modular components... calculates, learns based on physics, not less transparent black boxes"
