It is ultimately a hardware problem. To simplify it greatly, an LLM neuron is a single input single output function. A human brain neuron takes in thousands of inputs and produces thousands of outputs, to the point that some inputs start being processed before they even get inside the cell by structures on the outside of it. An LLM neuron is an approximation of this. We cannot manufacture a human level neuron to be s…
> To simplify it greatly, an LLM neuron is a single input single output function. A human brain neuron takes in thousands of inputs and produces thousands of outputs This is simply a scaling problem, eg. thousands of single I/O functions can reproduce the behaviour of a function that takes thousands of inputs and produces thousands of outputs. Edit: As for the rest of your argument, it's not so clear cut. An LLM can…
I think it's more than just scaling, you need to understand the functional details to reproduce those functions (assuming those functions are valuable for the end result as opposed to just the way it had to be done given the medium).
An interesting example of this neuron complexity that was published recently:
As rats/mice (can't remember which) are exposed to new stimuli, the axon terminals of a single neuron do not all transmit a signal when there is an action potential, they transmit in a changing pattern after each action potential and ultimately settle into a more consistent pattern of some transmitting and some not.
IMHO: There is interesting mathematical modeling and transformations going on in the brain that is the secret sauce for our intelligence and it is yet to be figured out. It's not just scaling of LLM's, it's finding the right functions.
