@futurebird For people who aren’t going to be practitioners in the field, the history bit is usually the most valuable part of a science course. Anything else is a snapshot of current knowledge, but understanding how that knowledge is built and the misconceptions that led people down the wrong path is far more valuable.
Even as a practitioner, often the hard part of understanding a system is not what it does, but what constraints used to exist that made people build it that way (and do they still exist?).
