I'm sorry, is there a massive problem of adult teachers and staff at school being constantly glued to and distracted by their phones such that it prevents them from teaching and doing what they are otherwise there to do?
No?
... Maybe the critics can ask ChatGPT what a false equivalence is.
We had early smart phones back I was in high school.
We also had this rule.
Its fine.
If its not fine, you have an addiction problem, and should seek help.
