On the other side, advancement in quantum computers would make current LLM inference much faster. Because of the extreme cooling needed, i dont think the energy demand would become less.
With AI companies talking about AGI, i sometimes wonder if they really need the machines for serving inference to customers, or they have a formula for computational capacity that could run an AGI, and they just want to reach that level.
Last I heard researches simulated an entire brain of a fruitfly with just a classic neuron approach [0] and if I recall it worked great.
I know a human brain is many orders of magnitude more complex, and that there are some birds that use quantum navigation - so it's certainly not impossible by any stretch, though I am quite interested in this statement since it's the first I hear about it.
