The new book by Paul Duffy · Coming spring 2027
Empty air is the most abundant resource on earth. AR and AI are about to turn it into value. The Spatial Realm shows you how.
Hardcover, paperback, ebook and audiobook. Pre-order details coming soon.
The big idea
Most of the world around us is dead space, empty air. It is the most abundant resource we have, and almost none of it earns its keep.
People, products, places and data appear right where you are, through light glasses or the phone in your pocket. You stay in the room.
Whoever tells the best story in that space wins the audience. The book is a playbook for doing it first.
