I agree that computing confined to a rectangle is limiting and stifling. The long-term solution in my mind is everyone having an AR headset. I would love to be able to project code and objects all over the room and be able to code any place anywhere. The technology clearly isn’t there yet though, so I understand dynamicland’s paper and projector model.

My very very long-term dream about computing is something like nexus in the Nexus Trilogy[1]. Written by an ex-Microsoft dev, it’s a really great hard sci-fi cyberpunk take on the future of computing. Highly recommended!
