It's generational in the sense that younger generations are far more accustomed to using phones than computers. They might not even be exposed to a computer until they need to use one for school. It's objectively less comfortable for them to use a computer when they never (or barely) used a mouse, physical keyboard, or any of that software before.

You can even see the same with games. All these kids growing up playing games on their iPads are really good at using those crappy touchscreen controls to play. Do you think they'd find using a physical controller comfortable? Maybe after a lot of practice, but why switch if you're already good at using the touch controls?
