Except we very much still use analogue clocks. They’re everywhere. Being able to read a clock when your cell phone isn’t handy is still a useful skill. And it’s not like it’s that hard to learn to read one. If you can’t figure out an analogue clock with a few minutes of instruction, well, you’ve got bigger issues.

I've had the opposite experience. I learn many things I don't use because knowing them makes me see and think things differently and expands my mind.

Absolutely do learn things you don't think you need. Everything will be useful eventually in life. I've proved that to myself many times.

“Don’t learn what you don’t use”

Sure but if you wear an analog watch you just learned how to use your analog watch. It’s not that hard

Be careful not to melt your tiny brain by learning something as easy as reading an analog clock.

Speaking as someone who writes in cursive, has a couple of nice clocks and watches, and can drive a manual transmission... Yeah, times are a changing. I think it is fun to learn those skills, but not necessary. My school didn't teach me how to hitch up a team of horses, nor how to sharpen an axe or load a flintlock musket. Digital clocks are cheap enough and common enought that learning analog is not strictly necessary.
