The true number must be considerably less than that because that's the recipe for building an entire human being, not just the brain, and the genome contains a huge amount of redundancy, 750 MB is just the upper bound. > *> Humans no longer write the algorithms these neural networks derive, the > training process comes up with them.

And we know from experiments that a typical synapse in the human brain "fires" between 1 and 50 times per second, but a typical transistor in a computer "fires" about 4 billion times a second (4*10^9). It also has 9.2* 10^15 bites of fast memory. That's why the Frontier Computer can perform 1.1 *10^18 double precision floating point calculations per second and why the human brain can not. By way of comparison, Ray Kurzweil estimates that the hardware needed to emulate a human mind would need to be able to perform 10^16 calculations per second and have 10^12 bytes of memory. And the calculations would not need to be 64 bit double precision floating point, 8 bit or perhaps even 4 bit precision would be sufficient. So in the quest to develop a superintelligence, insufficient hardware is no longer a barrier.
