My only thought is that buggy whips were not needed once the automobile took hold.
Of course, electronic book Readers will be a huge success and old style paper books, including textbooks, will cause a decline in the use of printed books.
Those book readers will obviously be full color and full function and will almost certainly be the same as your main personal computer. They will do everything for you. It's just a question of time.
How could it possibly be otherwise?
