I am in the transition age range of people who have trouble reading analog clocks and I must admit I had trouble with it until I started wearing a watch as an accessory as a teenager. The issue isn't that it's hard, it's just something that you need practice at to do quickly and a lot of young people just don't look at analog clocks to tell time very often. It's not a matter of being stupid or not being taught how to do it, it's like mental "muscle memory" that just isn't built up in a world where digital clocks are everywhere, including in your pocket 24/7
