Mobility: You have the same influence everywhere you are. Office, home, public, none of it is relevant.
Telepresence: You not only control the message to your wife, or your children, or your father. You control the stock purchases under your control. You control a machine in Thailand from your home in New Jersey. You control what door at your home opens for whom and when; how dim the lights are; where your car drives without you there.
Interface: You don’t have to have your hands occupied. Your local devices track your eye movements, your brainwaves, your subtle finger movements.
Telepathy: Your local devices tell you facts about the people you walk by, so much as they want to share. Your whereabouts, the local choice of markets, specific devices you may be looking for and how far away they are, how much they are, and precalculate the cost-benefit analysis of given choices based on your values.
There are no written or symbolic signs. Nobody really bothers with words. Devices every which way beam lazers and emit wireless signals. Some people are genetically engineered with the intent of good health and physical versatility, but no need for a voicebox, eyeballs, or eardrums. A device uses the ocular nerves to transmit the maximum amount of information directly to the brain. These devices can be fitted with artificial eyes, ears, smell, text.
Futurism. Supposing that we take the sciences already known, and try to imagine them as fully developed as we suppose is realistic, and supposing large populations eagerly adopt these developments – what can things look like? Is my suggestion far off? Can you paint things dramatically different?
