The Paradox of Intelligence

In his 1950 paper Turing estimated that to pass his test an AI program together with all of its data would require no more than about 100 megabytes of memory. The laptop computer on which I'm writing this book has over a thousand times as much memory as Turing specified counting hard drive space and about a million times of speed though it is not clear from his paper what account he was taking of the brain's parallel processing but it can no more think than Turing's slide rule couldI am just as sure as Turing that it could be programmed to think and this might indeed require as few resources as Turing estimated even though orders of magnitude more available today. Why is there no sign of such a program intelligence
