Students also see power drills and cars, and schools don’t use them as part of the curriculum. I have a lot of computing device and still believes in real books and pen or paper for learning anything. The mechanical actions and the physical presence really helps in retention of the materials. Even those TI calculators can be overkill. I’ve only used one in college, and it was for a few exams about polar coordinates and transmission lines, IIRC. For everything else, the simpler scientific calculators were enough. Multiplying matrices and graphing functions doesn’t take that much time at high school and undergraduate level.
