The original question, 'Can machines think?' I believe to be too meaningless to deserve discussion.
Alan TuringIt seems probable that once the machine thinking method had started, it would not take long to outstrip our feeble powersโฆ They would be able to converse with each other to sharpen their wits. At some stage therefore, we should have to expect the machines to take control.
Alan TuringI 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.
Alan TuringThese disturbing phenomena [Extra Sensory Perception] seem to deny all our scientific ideas. How we should like to discredit them! Unfortunately the statistical evidence, at least for telepathy, is overwhelming.

Then he was suddenly heard to say: "No, I'm not interested in developing a powerful brain. All I'm after is just a mediocre brain, something like the President of the American Telephone and Telegraph Company."
Alan TuringWe may hope that machines will eventually compete with men in all purely intellectual fields. But which are the best ones to start with? Many people think that a very abstract activity, like the playing of chess, would be best. It can also be maintained that it is best to provide the machine with the best sense organs that money can buy, and then teach it to understand and speak English.
