While the previous diagram depicting the advances in processing power might make us look back in nostalgia over how far we have come, this same nostalgia will be wiped away quite fast as soon as we realize how far we still have to go.
As we saw in the preceding diagram, the computational power of the systems we have implemented so far are nowhere near that of a human brain. The neural networks that we devised (at least in this book) had a number of neurons ranging anywhere from a million (the equivalent of what you would find in a cockroach) to about ten million (close to what is common for an adult zebra fish).
Attempting to train a network that parallels a human mind, at least in the number of neurons used, is currently beyond the scope of human engineering, as of the date of this book. It simply surpasses our current computing capacity. Moreover, it is important...
