This is not about integrating or not integrating tech. Many schools do integrate interactive learning technologies.

The problem is that kids who are glued to their devices use them to tune out and avoid classroom work, for example constantly scrolling through TikTok. This is arguably a parenting issue, made worse by the fact that schools are afraid to punish misbehaving students in any way, but it's qualitatively worse from (and more common than) kids just looking out the window or doodling during class and still picking up at least some information.

For what it's worth, I don't see why this requires government action, schools can certainly set their own policies - but I guess that's how we roll in California, "there ought to be a law".
