tbf, when most of those posting here were children, access to smartphones/tablets with unrestricted internet connection wasn't a problem
but i do remember my parents actually raising me pretty hands-on, taking care of me not watching stuff I shouldn't be watching which of course existed and was easily available
Access to smartphones/tablets with unrestricted internet connection is only a problem today when parents give their children access to smartphones/tablets with unrestricted internet connections.
Cell phones and tablets don't spontaneously appear whenever a child wants one. Parents have the ability to hand devices over to children when they have time to watch them while they use it and remove those devices from them when they don't.
