I don’t normally engage in ‘what if?’ reflections, but one has variously struck me. Alan Turing (pictured) is credited with making a major contribution to shortening World War II by two years or more as a result of his work at Bletchley Park. Indeed, Baroness Trumpington, who worked at Bletchley, is convinced that without his work we would have lost the war, with the Germans succeeding in starving Britain into submission. Turing was convicted in 1952 of gross indecency. His security clearance was revoked. This point is generally overshadowed by the fact that he subsequently killed himself, but it is very relevant for reflecting on what might have been. Where would we now be if Turing had been arrested and convicted in 1939?
