It is estimated that a human brain uses roughly 20 Watts to work – that is equivalent to the energy consumption of your computer monitor alone, in sleep mode. On this shoe-string budget, 80–100 billion neurons are capable of performing trillions of operations that would require the power of a small hydroelectric plant if they were done artificially.
Currently but it’s a start and 100 years is a long time. 100 years ago we didn’t even have computers, barely cars, and doctors still didn’t really wash their hands.
Maybe more with less is possible, but we are currently doing less variety of skill with way, way more energy. From https://www.humanbrainproject.eu/en/follow-hbp/news/2023/09/04/learning-brain-make-ai-more-energy-efficient/
