"This stands out.. 'I believe that in about fifty years’ time it will be possible to programme computers, with a storage capacity of about 10^9, to make them play the imitation game so well that an average interrogator will not have more than 70 per cent. chance of making the right identification after five minutes of questioning. The original question, ‘Can machines think?’ I believe to be too meaningless to deserve discussion. Nevertheless 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. I believe further that no useful purpose is served by concealing these beliefs.'" - Alan Turing, 1950.

He was about 20 years out. And 1GB isn't nearly enough.. But hell, pretty good for 1950.

The whole paper is absolutely fascinating in a modern context.. https://academic.oup.com/mind/article/LIX/236/433/986238?login=false
