Is it still a book?

If you put on your XR glasses and walk into it, is it still a book? If the pages you are looking for appear as you wander through the room, is it still a book?

If the illustrations come to life when you play with them, is it still a book? If you can ask it a question, and it immediately puts together a little movie to act out the answer for you, is it still a book?

I say yes.
