This is incorrect. I'm a teacher and CONSTANTLY use the analog clock for multiple reasons.
It's the clock of record. Doesn't matter what YOUR particular clock says, the clock on the WALL is the time we all go on.
Reaching into your pocket to pull out a phone and look, no matter how much you want to pretend it's trivial, still takes SIGNIFICANTLY more effort and time than glancing at the wall. Those seconds add up.
Momentum. Are you PERSONALLY going to provide the billions of dollars in funding to replace every analog clock in a public space with digital ones?
This is not like learning to write cursive - reading an analog clock is a trivial skill that should not take longer than a day for anyone to master.
Don't worry...
We also have a brewing electricity crisis and not long before the classic console crisis.
