Quote by Turing, Alan
"We may compare a man in the process of computing a real number to a machine which is only capable of a finite number of conditions."
More from Turing, Alan
"I believe that at the end of the century the use of words and general educated opinion will have altered so much that one will be able to speak of machines thinking without expecting to be contradicted."
"The question 'Can machines think?' I believe is too meaningless to deserve discussion."
"A man provided with paper, pencil, and rubber, and subject to strict discipline, is in effect a universal computing machine."
"Computing machinery and intelligence."
