It has some interesting implications: If we manage to replicate a human-like brain in silicon, it could think multiple million times faster than the biological equivalent. So even if it needs a lot of energy to run, it could "out-think" us by orders of magnitude and would have crazy reaction times. Just imagine a sentient being with the human mental equivalent of millions of years in one year. Crazy.
But we know very little about how biological brains actually work and very few connectomes have been fully mapped as of yet. We still cannot fully explain how C. elegans with 302 neurons "thinks".
Also every neuron contains the entire genome, which is hundreds of millions to billions of base pairs depending on the animal and we also don't really know how important it is to the function of the brain.
So the "state" of biological brains is potentially utterly gigantic even for simple animals.
