The human brain stands as a marvel of biological efficiency. Despite coordinating a vast array of complex functions, from movement and sensory perception to memory and thought, it consumes a mere 20 watts of power – roughly equivalent to a low-wattage LED bulb. This remarkable feat is achieved through a combination of factors, including the brain’s highly specialized cells and its efficient use of energy substrates like glucose. In comparison, simulating similar levels of brain activity in artificial intelligence systems currently requires significantly more power, highlighting the elegance and optimization inherent in biological neural networks.
