Every now and then there is a major shift in the way we think about computers and technology. It's like this: we make screens bigger, better and more immersive, but they're still screens we have to put in place. At some point there comes a shift - we flip inside out - and suddenly we're not looking at the world with screens put on top, but screens with the world underneath. It usually happens when someone invents a new way of doing things, but it doesn't happen every time. You can't reach that change point with the same technology and the same way of doing things. We can cram more and more technology into the gaps in our world, but eventually we're going to run out of room between existing technology and methods. At some point, we have to redesign and leave old technology behind.
