yeah, too many school authorities do act taht way. For a approach going more in the opposite direction, see, for example: https://piped.video/watch?v=dk60sYrU2RU (maybe skip to aa minute in. presented, the idea, in that case, by sugata mitra. The Talk is not new, but still relevant I'd think, and relates to the post here. ) 💻🖥️
For anotger, similar, but also different example, see https://piped.video/watch?v=WNuv0_MLrKg this one specifically mentions phones early on, too.
So if you believe in, or are open to the idea, that the approach in in the main meme post isn't the best, then the stories in the piped videos might be of some intrest to you.
