I read somewhere that the Bell Labs scientists who created the CARDiac were worried that, thanks to transistorization, the next generation of programmers wouldn't understand the physical, material processes that unfolded when their programs ran, and that this would mean a loss of legibility and intuition and Fingerspitzengefühl. I can't track down the reference now, but it stuck with me, because the CARDiac is *such* a perfect way of preserving those virtues.
