Technology entrepreneur Raven Zachary has seen things he has difficulty talking about.
“It is a profound moment to put on the device and see an object on your table, and then to walk around that object and see that it is fixed there and behaving as if it were real. It is impossible for me to communicate the experience. You have to experience it for yourself,” says Zachary, cofounder of software firm Object Theory.
