I don’t fully disagree with what you say. I think social media also has some positives. The amount of transparency over government and exchange of knowledge and ability to learn is greater now than ever before. Hopefully we will swing back to a balanced lifestyle where phones and social media are just tools that people use in a limited way instead of being addicted to it.
My bigger fear of tech is how it’ll marginalize people economically and centralize power. We see it already with companies like Amazon. But the coming wave of automation over everything - manufacturing, entertainment, etc - may be far more damaging than even social media. Unfortunately right now it seems our political and economic systems are completely inadequate in preparing for this.
