If cleaning it isn't possible, getting kids to know it and navigate the filth is required. Same way we teach kids how to interact with people on the street and get a sense of who to trust when they're in trouble and how to avoid trouble in the first place.

I agree. However social media is so addictive that even if we are aware of its harm, we stil use it

I wonder if the next generation will be facing this same sentiment.

For instance TV was basically a drug for the last generation, there was people watching near 8 to 10h of TV a day. It might have been replaced by something else, but I don't think our current generation has this specific issue.

From that POV, currently people in their 30~60s are the more stuck to social networks and raging against fake news all day, while younger generations tend to be on different services with potentially a lot more reduced circle of users.

Do we really know how the generation that is 5~6yo right now will react to our social media landscape ? (put another way, are we fighting the last war ?)
