I run text through text-to-speech while reading visually to double my attention.
In this case, I swiped down with two fingers to start iOS' speech function and it read the article quite quickly for me. I was able to better follow along with the reading as it highlighted words on the page. So while I won't say the article is wrong in absolute terms -- it's definitely a different experience to "speed read" in any practical manner than to read each word carefully on your own -- I do think some speed up with assistive tools or training is possible. :)
