Who is this "we"? Are you talking for all hundreds of thousands of schools of the world? All schools of France? Who are you speaking for?

I think you should read again my comment, the "we" doesn't refer to anything you mentioned.

"We" as people in developed countries who have the luxury of having kids in high school with smartphone.

Let me rephrase that.

People in developed countries don't work the same way as a 100 years ago. (farming, manufacturing, etc.)

People in developed countries don't entertain the same way s a 100 years ago. (social media, TV, etc.)

Almost everything is different. So, why are we trying to teach the same way as a 100 years ago?
