It can also far more emotional and evocative, while reading can be more analytical.

The layout genuinely hurts my eyes to read. I have vision problems and the continuous picture changes after every sentence is very uncomfortable to view. The contrast changes rapidly from bright to dark or completely black. Then there are light pictures with white text rendered over them. After the first few "slides" I had to close the article. It was too uncomfortable to read. Perhaps you should think before you run with your ableism.
