I regularly see the phrase "all Xs are Ys, but not all Ys are Xs" in teaching material. Even material for children! I have to re-read it every time. I very much prefer "Y is a more general category than X" or "X is a subset of Y". Do people find this phrasing helpful, or is it poor pedagogy?

One day I am going to reach the height of technological sophistication, and every clock in my house will handle daylight savings automatically. I'm not there yet. I think modern appliances are getting better though. (Does a microwave really need to know the current time?)

I travelled recently with six electronic devices, and every single one used USB-C for charging. It was wonderful, and not an experience I've had before.
