We absolutely have a canon. You show me someone who has studied Dikjstra, Turing, Hoare, who has taken the time to pour over the Art of Computer Programming and Structures and Interpretations of Computer Programs, and poured over Ivan Sutherland, is familiar with the early days of IBM, Fairchild, Xerox PARC, and hundreds of other classics we consider to be "canon" that I am surely missing (just shooting from the hip here), and you'' be showing me, more likely than not, a damn good programmer. We have a canon, we just don't have the same studios, detail-oriented attention spans we once had, and the technology we have built is partly to blame.

Maybe related, you were once considered an ignorant brut in this country and others if you haven't read a library of literary classics, now we have kids growing up who barely know Shakespeare, or the rich body of the writing of the abolitionists or slave narratives (how many people you think in this country that even know 1/100th of what Henry Louis Gates Jr knows?) Do you think W.E.B Du Bois and Booker T Washington are common names anymore? I remember when everyone had the preamble of the Constitution and the Gettysburg Address burned into their minds, now we can't be expected to remember questions for a simple AWS Certification Exam, it's pathetic.
