8-track tape has few (if any) aficionados, due to its self-destructive media and scarcity of quality playback devices.
Physical books, on the other hand, require no special playback technology and are arguably one of the most perfect user interfaces ever devised. I have century old books in my library that are still fascinating and useable, in contrast to my collection of audio tape, floppy disks, and even some CDs that can no longer be read reliably (my vinyl still works, though). It feels a bit premature to declare the end of physical books.
