This is unrelated to my original point, but... A quick search found this, though it'd be disingenuous to say that neuron connections represent storage space. On one hand, there is plenty of space to store information within the biological contents of each neuron (Receptor count, exoskeleton structure, etc), all of which represent state information and affect each neuron's function. On the other, scientists still don't have much clue what information is redundant and what is essential. I'd take 4 terabytes with a grain of salt. The rest of your comment is just philosophy and speculations, neither of which I'm interested in discussing at this moment...Space: the human brain is roughly 4tb (forgot source, I'm sure a quick google will bring one up).
