I am dyslexic, didn't learn to read until very late, and had parents (in the 80s) who refused to let us watch TV or see films. I sneaked away to see whatever I could, and I think it caused real damage that I had no understanding of a whole world of stories because of it. I love watching cartoons with my DD and I was delighted when she started being able to concentrate long enough to follow a storyline.
It is utter nonsense that books are somehow 'better' or 'cleverer' or 'more imaginative' than any other medium.
I find it very telling that the author of this humblebrag claims she 'did a big piece of research' on the subject. I clicked the link and ... it's a small survey, not a piece of research at all!
