This are possible extracts diary entry from the perspective of a new visitor to space:
As the spaceship approached the docking zone, I noticed that the space city had tubes and looked like a cluster of cylindrical tanks and rectangular blocks linked together. Inside one of its bedrooms, I saw a white wall crawling with “beetles” that emitting a soft, orange glow. They were about the shape and size of computer mice and are robots that gently scrub the walls clean.
As I thought of changing the color, these beetles became pinkish. Realizing that it was reading my thoughts, I commanded the lights to dim. Outside the room, a multi-segmented “snake” robot slid past, taking environmental sensor readings and checking for any fires.
In another room, I thought of contacting a friend. As her picture floated into my mind, I visualized a place to meet. Instantly I was with her in the garden under the tree that I visualized. Every breeze, word and object was as real to me as it was in reality. I was stunned: this was just like magic.
My friend told me that there were also many people using the same place as us, and yet we will not be able to see them. I requested to see how this system worked, and she told me to close my eyes and open it after a second.
I did so, and I suddenly saw myself at the Niagara Falls. There was a huge crowd of people all over the place. A young couple sat perilously on a small tree hanging from a cliff. Many people were levitating in mid air along with their picnic baskets. Some sat chatting with their friends on the edge of the waterfall.
My friend waved her hand, and suddenly, all the people disappeared. Alone, I realized that each person could have the entire world to himself or herself in virtual reality, in any manner that they chose. They could share fantasies, memories and dreams effortlessly.
As I toured the space cities in my new home-ship, I saw a spaceship docked to an asteroid. Within it, a young couple from Europe was building a home for their new friend from Africa. The microscopic robots embedded in the wall of their spaceship was digesting the asteroid and creating a new ship right in front of their eyes.
This used the same technology as the mini-factory. About the size of a wardrobe, it could manufacture almost any desired item from daily life that could fit into it. Simply go to the Internet to download a blueprint of anything you like. Throw some rubbish and asteroid fragments inside. Over the next hour or so, the machine will disassemble the waste matter and use it to construct the desired item at the molecular level. There was no need for the money, shops or factories of the early 21st century.
The successor to the Internet hosts massively distributed databases that function much like the Wikipedia in early 21st century, providing the totality of all human knowledge and technology free to everyone. With their survival assured by technology and computer automation taking care of mundane chores, people volunteered to be product designers, robot programmers, galactic explorers, scientists, child guardians and more. Personal armies of supercomputers and microscopic robots backed every individual with the power and resources of a mammoth organization.
This is a world of peace, diversity and open disclosure. It must be, for everyone held God-like powers and could potentially destroy the entire human civilization with the technology available in their house. Yet the idea of such terrorism was unthinkable.
Personal factories fulfilled all material needs. Virtual reality provided entertainment, adventure and education superior to any physical experience. There no longer existed any need to attack or hurt another being to obtain whatever people desired. If they wanted to do anything that might harm another, they would do it in virtual reality.
