> Now, large tech companies haven't wholesale killed people (unlike say tobacco, or talc powder, 3M and half of their solvents, weed killer, most car makers, etc etc)
It's nearly as bad. Social media causes addiction and mental health problems especially for the youth. PISA scores are going down. It can already be seen now, although not many 20 year olds have had a smartphone for more than 10 years. Here in this country every 7 year old has a smartphone and it will get only worse. Physical health is impacted because of kids are tapping on a screen instead of running and playing. It has impact already to language learning and social development of babies because parents interact with their smartphone several hours a day and instead of interacting with their baby.
Of course there is other tech than social media and smartphones. But at least in these areas equally strong regulation as for tobacco and alcohol would be required.
