It is a living field, of course, but I do think there are certain texts that we know we would include from Turing, Von Neumann, Goedel, Church, Shannon, Backus, Hoare, Dijkstra, and I guess something about Perceptrons is now mandatory but IDK what text I'd choose. Beyond those texts things become hazier, but that's already at least a semester of undergraduate reading.

Yeah, Euclid is important. It should be studied carefully in any Great Books program. But there's a lot of other important stuff to talk about and the extreme emphasis on Euclidean constructions is IMO a bit of a shibboleth.
