Daniel DENNETT :: "What Darwin and Turing had both discovered, in their different ways, was the existence of competence without comprehension." [23 June 2012 is Turing's 100th Birthday!] - http://www.theatlantic.com/technol...
"This inverted the deeply plausible assumption that comprehension is in fact the source of all advanced competence." \\ Turing remarked how a human mathematician makes blunders when trying out new techniques, then wrote, "if a machine is expected to be infallible, it cannot also be intelligent." - Adriano
