Interesting question posted on Quora, “What are some systems we live with today that were designed for a world of the past?”
Some examples from the most highly rated answer are train rail distances, modern plumbing, and more surprisingly to me television remotes and the positions of windows in homes. I say surprisingly because I’ve heard train rail distances and modern plumbing described as based on old systems, while the other 2 I hadn’t thought about before.
There are obvious, but interesting, well reasoned thoughts on education, media distribution, and American health care (based on when people worked for one company for life).
I like this one about piano keyboards.
If instead, we had a keyboard structure that was truly black/white chromatic (with perhaps another color indicator for all the C’s on the keyboard to enable judgment of where you are within an octave), the student’s problem of having to learn 12 patterns (roughly) for each structure would be reduced six-fold. There would only ever be two patterns to learn for any given structure.
I couldn’t find a post on MetaFilter on the same topic, but I bet there is one. Here are all posts tagged ‘Obsolete’. Also, in a quick search couldn’t find one on Reddit, but I think this question is perfect for both of those communities…
