Human Brains Are Far More Power and Data Efficient

Humans are doing something different from current AI models, evidenced by efficiency: the human brain does remarkable things on about 20 watts while AI techniques use kilowatts for equivalent tasks, and humans learn from far less data (a 16-year-old learns to drive in far fewer miles than self-driving cars need)—suggesting there are still tricks to learn beyond merely scaling models up, though scaling alone also pays huge dividends.
