Ah. In that case, the existence of books (even popular ones) and ACM conferences isn't strong support that most devs are well-versed in computing history, to me.
In the same way that the medical field has similar historical output, but the number of everyday doctors versed in medical history is quite low.
I'll dig around today and see if I can find representative polls related to computer history. Surely SO has asked a question at some point...
