At the time, Waterhouse could not understand why Alan would want to move away from Bletchley. But now he knows how Alan must have felt after they turned decryption into a mechanical process, industrializing Bletchley Park. He must have felt that the battle was won, and with it the war. The rest might seem like glorious conquest to people like the General, but to Turing, and now to Waterhouse, it just looks like tedious mopping-up. It is exciting to discover electrons and figure out the equations that govern their movement; it is boring to use those principles to design electric can openers. From here on out, it’s all can openers.
