You're spot on with classrooms not needing tech though. They add complications and distractions on top of an already difficult task.
They almost let us play RuneScape (something something medieval history?) until they saw me firebolt a rat and declared it unacceptably violent.
I visited my old school once, a few years after graduating, and was startled to see many people on their laptops in the hallways. I guess they had become required. I had graduated right around the time smartphones came out, and we didn't have laptops either. (You'd see a laptop at school occasionally but it was a rare sight.)
I'm glad the fanciest thing I had was a TI-84, because it got me to spend most of my time socializing, which I think was pretty good for my development.
Was pretty impactful for my education, just not in the intended way
