In response the mayor promised new investment into sports, recreation, libraries and book sharing... In other words, there's more going on here than just the "phone ban", but a broader attempt to reconnect and rehumanise the village life.
My concern is that even with the social and financial will to restore a more convivial lifestyle, those young people won't be able to engage. Having been raised by screens they are already so psychologically altered (damaged?) as to be lost.
The assumption that life can "go back" may be misguided, and that makes this an experiment worth watching.
