We live in a dancing matrix of viruses; they dart, rather like bees, from organism to organism, from plant to insect to mammal to me and back again, and into the sea, tugging along pieces of this genome, strings of genes from that, transplanting grafts of DNA, passing around heredity as though at a great party.
Any real virtual reality enthusiast can look back at VR science fiction. It's not about playing games... 'The Matrix,' 'Snow Crash,' all this fiction was not about sitting in a room playing video games. It's about being in a parallel digital world that exists alongside our own, communicating with other people, playing with other people.
It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. The two apparently dissimilar approaches were proved to be mathematically equivalent.
