I think that's overstating it. For long-form, linear reading of text books are great, but there's a lot of places where I much prefer hypertext or other media.

I think that's overstating it. For long-form, linear reading of text books are great, but there's a lot of places where I much prefer hypertext or other media. Anything with copious footnotes, references, and appendices is just so much easier to immediately click to the highlighted reference link, quickly scan the reference, and then jump back. Flipping through pages to find the right reference and then flipping back is a rather large context switch in comparison. A bookmark still isn't quite robust enough because I still need to scan to find the exact reference when jumping out from the text. This is why e.g. I read modern hyperlinked PDFs and Wikipedia articles faster and absorb more than their dead-tree equivalents (although I find I read dead-tree equivalents faster for longer linear reads). And that's just non-interactive, text-based media. Video tutorials for quick how-tos are way way more effective for me than the equivalent book. I haven't had quite as much luck with interactive articles, but there have been a few gems that simply wouldn't be possible with a book (e.g. https://ciechanow.ski/gears/ https://ciechanow.ski/gears/).
