The real bottleneck is software. Creating software can be done only the old-fashioned way. A human -sitting quietly in a chair with a pencil, paper and laptop- is going to have to write the codes... One can mass-produce hardware and increase it's power by piling on more and more chips, but you cannot mass-produce the brain.
The fate of the physiology of the brain is independent of the truth and falsity of my assertions relative to the laws of the organization of the nervous system, in general, and of the brain in particular, just as the knowledge of the functions of a sense is independent of the knowledge of the structure of its apparatus.
The mother was holding a baby, had a stroller with what looked like twin girls around three, and had a five-year-old boy who was running around the shelves with a finger shoved up his nose. I considered warning him that if he fell, he would poke his brain out, but it struck me that losing intelligence was not something he was worried about.
