I was amused by speculating what he would have thought of the newfangled technologies back in the 18th and 19th centuries (my current history reading) since his definition of a mature perfected tech seems to be 'has been around in some form for 2000 years'.
Maybe he'd have been one of the people convinced that traveling at 30 miles per hour couldn't possibly been healthy.
For me, when reading scholarly books in paper form, I badly miss hyperlinked footnotes and search functions. A particular pleasure has been using the Faithlife platform (on my tablet) for study purposes (I've stuck with highly discounted packages and books plus the free versions of the software) as they've hyperlinked their books to each other so that if I click on a citation for a book I own, I can navigate to that book.
On the other hand with fiction books I often want to poke around to find that bit I really liked or skip ahead to see how things will be resolved (I'm a self-spoiler). Fortunately I've found chapter links and slide bars to provide reasonable navigation particularly when I remember to add bookmarks.
And of course there are art books and the like which work best in paper form.
