Not to disregard Turing here as I believe he is still one of the greats of computing, but the idea that he “Almost Singlehandedly” did anything is to the discredit of the thousands of workers at Bletchley Park alongside him, and the Polish cryptographers who initially cracked several versions of Enigma in the 1930s and went on to teach the Bletchley how they did it.
It’s fine! We’re gods!
