6.6 Worlds without end
I wish this section could have been longer and that I could have written about:
mirror worlds which are exact digital representations of parts of our own world – cities, hospitals, and so on – and which are constantly fed data that keeps them up to date;
autonomous robots that move through the real world, sensing it, responding to it and changing it;
artificial life: worlds like Tierra, teeming with digital organisms;
telepresence in which it is possible to interact with a virtual representation of some real scene, perhaps from thousands of miles away. For example, using telepresence, a surgeon can operate on a patient without being at the scene.
But you may not share my wish, so I will just move to the final section, where I raise a few concluding questions.
