And yet, strangely, Americans are probably reading more words than ever before.
This sentence undermines the whole article.People do read more than ever. But we don't recognize it as such. We read on our phone while intermittently reading subtitles of Netflix in the background. We read every time we look at a computer, phone, advertisement etc. But we only count reading paper as "real reading".
The shape of reading is changing yes. I think the "deep" thinking associated with reading has always been a bit of an elitist idea. Why would reading 1000 words of a great philosopher be any different from reading 1000 words of smut online. In some way losing this kind of stigma will make reading more accessible.
Writing and publishing is dying first. And that has to go long before reading dies anyway.
