All these platforms seem explicitly designed to exploit insecurities and encourage a mindless mob mentality. It's the antithesis of individualism and I cannot see how it could possibly improve one's life (at least, before you have the maturity to be comfortable in your own skin).
The more I read articles like this, the more I think the whole thing is pure toxicity.
I don't know how realistic or practical it's going to be to ban smartphones/social media, while still encouraging programming, internet research, experimentation and so on.
