These could be the first text books where you can scribble as much as you want and with a wave of the magic wand it's brand new again. Intriguing, right?
Let's bet that'll never happen. The "perfectly recyclable text book" is a nightmare for business people.
When I went to school, books were handed down many times, from student to student. Nowadays they FORCE the students to write in their books, just to sell new ones every year. It is a GREEDY world.
