I thought the same thing until someone asked me how many of them have been able to overcome digital addiction and set a path ahead that's healthy.

Being literate in something isn't just knowing how to use it, but how to manage it's use for one's self and for others.

Once you see the importance of it, knowing where/how to start to manage what kids are exposed to that is age or developmentally appropriate for them is entirely a different skill to meet and manage the digtial literacy of another human, especially a child.
