Spot Draves, the dude who made Electric Sheep, once described cyberspace as “infinite dimensional”. When I asked what he meant, he meant that every connection was orthogonal to everything else, and that you could instantly connect to anything by uttering its name. It was like space where you could get anywhere by introducing a new dimension where the distance, along that dimension, from you to that place was zero.
He also told me, in that same conversation, that he thinks this universe might be a 3D simulation running in a 2D universe. It was a fun conversation.
