They've been predicting the end of the book for 100 years

In 1910 a French cartoonist named Villemard predicted how book content would be repurposed in the year 2000. When he drew this picture, radio had been in use for over a decade, but apparently M. Villemard couldn't imagine textbooks being transmitted wirelessly. Or maybe he just thought it looked funnier with wires.
The headsets would have looked right at home in a high-school language lab, circa 1970. I love how the students have no pencils or paper, as if they're downloading their lessons right into their brains.
