In #MathsToday we talked about cryptography. First, how cryptographic systems don't matter if you just share your data (there are many examples). Then rot, substitution, one-time pads, Vigenère, Enigma, and finally public-key.

It struck me is that we have talked about Galton, Fisher, Pearson --> Hitler, Watson (IBM), WW2 --> Turing and Enigma, Turing and AI --> IBM and Watson (computer) --> current tech bros & TESCREAL.
Tech history is so instructive and insightful. History offers so much benefit to technical curricula.
