We do know how much energy a human brain uses to do whatever it does though.

That it takes vast power to train the LLM’s (and run them) to not get intelligence is pretty bad when you compare the energy inputs to the outcomes.



Energy is even weirder. Global electricity supply is about 3 TW/8 billion people, 375 W/person, vs the 100-124 W/person of our metabolism. Given how much cheaper electricity is than food, AI can be much worse Joules for the same outcome, while still being good enough to get all the electricity.


Rice is 45 cents per kg in bulk, and contains the equivalent of 4kWh. Electricity is not actually much cheaper than food, if at all.
