SICP: the end of an era (2021) [video]
This made me sad.  Sussman is saying -- almost literally -- that MIT just threw in the towel on teaching actual understanding of how things work and instead went with treating engineering artifacts as magic black boxes that no one, including the people who created them, actually understands, and that <i>this is OK</i>.  It is not just that no one <i>does</i> understand them, no one <i>can</i> understand them, and so we're stuck with them because if no one can understand them, no one can improve upon them.<p>Which is, of course, a self-fulfilling prophecy.
