While it’s true that a human brain only uses ~20W of power, it’s a really specific kind of organically delivered power with all sorts of environmental requirements that we, being humans, take for granted, but in the bigger picture it’s really a rare location in this universe that doesn’t kill us nearly instantly - much less provide that 20W of power in a form a brain can use.
So my GPU is about 300 watts and a still blatantly stupid LLM can write a little faster than me. Take off 100w to bring that down to my own writing speed then make it 10x slower to turn that 200 watts into 20 watts. Even with that heavy bias in the LLMs favour (forgiving it the entire power cost of my PCs other components that it partially utilizes) what we get is something slow, dumb, and incapable of learning because any local model is statically weighted.
Now, take your privileged writer status human brain and factor in all the other power required to keep it comfy in an air conditioned room, the labor required to put a roof over your head, keep your home plumbing working, make your food, deliver you pen and paper to write with - or are you using an electrically powered appliance to record and later communicate your thoughts? Oh, did you need to go to sleep for a while?
Might be because AI isn’t cognitive or actually intelligent. I imagine a washing machine wouldn’t do well either.
So true, and the things that LLM agents are good at, humans test very poorly by comparison, particularly on speed.
To be fair, run an LLM on a machine with an equivelent power requirement to the human brain and we might se some different results on that one.

@CheeseNoodle @MangoCats so like 20 watts of power? Yes that seems fair

That’s one way to compare it.

Do I get to include the gargantuan cooling system for the data centre and all the infastructure required to keep that going?
Total impact is the only fair comparison. Pollution from the power plants included, sewage treatment from the houses too.
