The elephant in the room is that there are differences in screentime. If one child grows up on DragonBox, Scratch, and Logo, and another watches cartoons and plays Jewel Candy Crush, it's really not the same.
For sure. I asked my med school professor friend about the differences between different types of screen time, and unfortunately neither he nor his twin brother (himself a neurosurgery professor) was able to say with any certitude which types of activities would be OK, or why certain activities would be more or less harmful.
Obviously the example you gave makes intuitive sense, but there doesn’t seem to be any research or other evidence to support it at this time.
