Slight sidetrack, but Ian McEwans Machines Like Me the alt. universe story where Alan Turing lived into the 80s is still available to download on iPlayer radio for another couple of weeks.
In that world Britain lost the Falklands but the Internet was like now but 40 years sooner. Presumably due to Turing's benign influence on the entire promotion of IT.
The real story is a bit like C4s 'Humans' and a good one at that.
