Describe the ways reading and publishing are presented in "the light at the end of the publishing tunnel? "

In The Light At the End of The Publishing Tunnel? by Rudy Shur, the author covers how, contrary to popular belief, virtual versions of books are not necessarily the saviors of reading as a whole. He explains that even when people may access books for free, nations are reading less by the day. The author ends the article stating "For all those who may think that selling our titles as e-books is the light at the end of the tunnel, I have a tip to pass on. Don't be too surprised if the light is attached to a speeding train heading toward you—toward all of us.". So, while at the beginning of the article publishing format is presented as the savior of reading, the end of the article states how it might be its doom.
