Of course the kids don't know how to read them. Kids rarely encounter analog clocks and when they do, they have several digital clocks within arms length. Most people wouldn't reach for a slide rule when they have a calculator.
And to be fair, analog clocks are objectively worse than digital clocks in every way aside from aesthetics.
I can feel the difference between 71 and 73 in my house.
At 73, my kids room is uncomfortably hot. At 71, it has a perfect chill for sleeping.
