I think when it comes to screen time, it's important to differentiate between passive and active screen time. Passive screen time is when the person is in "receive only" mode (e.g., watching a movie, a YouTube video). Active screen time is when the person is engaged (e.g., playing a video game, using an app, on a Skype call with friends). There are studies that indicate that the brain processes these two types of screen time very differently.
I agree with this.
There is so much junk online these days and to sit one's child in front of "educational" media without first vetting it is not going to go out well. ("Go out well" to quote my DS)
