This just feels like more social panic pandering from Hochul. I sincerely doubt this will have any appreciable affect on kids well-being. My older kid's high school just leans way in. They use phones in class for tasks. They watch videos, do research, use calculator aops, Google Classroom. The teachers who won't answer email are the ones who are just being stubborn.
Is that relevant to the cellphones-in-school bit?
