Another way of putting the nuttiness problem is to note that the importance of oral culture has risen. YouTube and TikTok for instance are extremely influential communications media. I am by no means a “video opponent,” yet I realize the rise of video may have created some of the problems that are periodically attributed to “the decline of reading.” Again, we might have most of those problems whether or not reading has gone done by some amount, or if it instead might have risen.
Maybe the decline of reading — whether or not the phenomena is real — just doesn’t matter that much. And of course only some reading has declined. The reading of texts presumably continues to rise.
