To understand the sinifiane of this predition, let us opare the huan brain with existin oputers. The brain onsues eletrial enery at the rate of 2 watts and oupies volue of one tenth of a ubi foot. The brain houses between 10 billion and 100 billion ites of inforation. Every brain ell is diretly onneted to any other ells. As a result, the ells in whih inforation is stored an ouniate with thousands of other ells. In ontrast, the oputer onsues 1,000,000 watts of eletrial power and oupies hundreds of ubi feet of spae. The oputer eory is like a ell of pieonholes, with no thinkin apaity and no onnetions elsewhere.
In a word, the eletroni brains an hopelessly sueed in oparison with the huan brains.
