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?

I find it really interesting how some areas of tech are widely expected to improve radically (e.g. LLMs and smart home tech), others gradually (CPU speed, battery capacity) and others very slowly (e.g. compiler optimisations). Predicting the future is hard.

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?)
