In schools there should be a class about safe internet use and it should be mandatory to write an essay about the benefits children get personally from using social media as well as the downsides.

Saying this as a current high school student: there should be as few mandatory classes as possible. Your maths, sciences, and Englishes make sense. In Ontario, we also have to take French (bit more iffy, but I guess it's an official language), Civics (fluff), careers (more fluff), and technology and the skilled trades (I like technology, but still fluff). The more classes you stuff into school that don't relate to what a student wants to pursue, the more disengaged they become. Ironically, if this were a class, I, and most others would be on our phones for pretty much all of it.

There has been for like 15 years. At least around here, well withouth the essay. I'm not sure what the essay would do, it would be written by a LLM anyway. Don't worry, LLM usage and risks is the next class we're beginning to teach as a society. Of course my own generation won't get that, so we're going to be fun "boomers" that way.
