If I’m watching a fascinating TED Talk at home, I don’t need anyone to make my favourite tv show boring in order for me to pay attention.
You’re comparing a TED Talk that you chose to watch to school curriculum.
I really hope you’re not a teacher or a parent, because your ideas seem not just ineffective but actually borderline abusive.
I’m a parent who has witnessed the effects of smart devices on children, and I have made serious mistakes in this area. Those mistakes are from being not restrictive enough. I believe the society has made similar mistakes, but is slowly turning to facing and understanding those mistakes. A generation has been lost, though, and some people (like yourself it seems) are still fighting against countering these problems. I hope you’re not in any role where you can decide these things, because I think your opinions around this seem very harmful to both individuals and society.
