Let's try to look a hundred years ahead and imagine what life on Earth will be like in 2119. Let's try to see the world through the eyes of our descendant.
Nanoworkers in an immortal body
So, suppose I am a man of the XXII century. I am over a hundred years old. Yes, yes, I was born at the time when you are reading these very lines, and I am still alive! And I'm not going to die, since humanity has long crossed the threshold of immortality. This is not surprising, because back in 2006, Professor Richard Miller from the University of Michigan said that he and his colleagues had managed to increase the lifespan of laboratory mammals by 40%. Later, scientists applied similar technologies to people, and by the 2050s, centenarians began to feel no worse than the 60s of the 2000s. And by the end of the XXI century, mankind has completely acquired immortality.
I don't know any diseases. For me in the XXII century, the word "cancer" means about the same as "plague" and "cholera" to you. Now medicine conquers any disease. The secret is in the little cleaners - nanorobots that inhabit my circulatory system. They rush around the body, correcting all flaws, eliminating cholesterol deposits and cancer cells, destroying harmful microbes. In general, everything happens exactly as the English science fiction writer Arthur Clarke once dreamed. If I get seriously injured: a spinal injury or I lose a finger, or maybe even an arm or a leg, it doesn't matter. In this case, there is a “regeneration pill.” I swallowed it, and after a while I was back to normal: all organs recovered, and the limbs grew back. The emergence of such technologies was predicted in the mid-2000s by Professor Ellen Heber-Katz of the Wistar Institute (Philadelphia). “At the beginning of the XXI century, humanity will get rid of cancer. The day will come and the cancer will be chained in "iron chains," said the great seer Vanga once. As you can see, she turned out to be one hundred percent correct. By the way, "iron chains" are my body. After all, I am half cyborg, like any normal person of my era.
Steel-muscle telepath
Since ancient times, people have worked on themselves - they have improved their body and spirit in order to acquire phenomenal abilities: the ability to read minds, have super-fine hearing, see the invisible and have an unsurpassed mind and incredible strength. All this was given to me by high technologies.

A microchip is implanted into my brain, with the help of which I can transmit thoughts at a distance: communicate with other people, control computers and robots, play video games. Basically, this technology is not new. Back in 2009, engineers at the Japanese firm Honda Motor created the Asimo telepathic robot. He carried out the commands given by a person with the help of a special helmet that converts thoughts into radio signals. This discovery first became an excellent help for bedridden patients, especially paralyzed ones. Subsequently, telepaths made all people, including healthy ones.
By 2025, scientists have developed artificial eyes, nose, ears, skin. This not only improved the natural senses of people, but also opened up completely new, previously unknown sensations for them.
In the XXII century, the boundaries between biology and cybernetics will blur, and a person will be little different from an android.
I live partly in a virtual world. I have contact lenses with Internet access in front of my eyes, and if necessary, I have all the necessary information about the surrounding reality: a map, a navigator, characteristics of objects, historical information. Also, these lenses are able to recognize the facial expressions of the interlocutor, and if, for example, my opponent is a foreigner, I see or hear a translation of his speech. Back in 2011, Professor Babak Parviz from the University of Washington spoke about the possibility of creating such a device.
I have an excellent memory, and Einstein himself would envy my mental abilities, because my brain is connected to a computer. Most of my body parts have been replaced with artificial ones, which makes me incredibly strong. In general, the scientist from the Massachusetts Institute of Technology Rodney Brooks was right, who at the beginning of the XXI century said that someday the boundaries between biology and cybernetics will blur, and a person will be little different from an android.
"Liquid" house with a toilet diagnostician
I live in an apartment that constantly takes care of my health. While I take a shower, the shower stall scans my body and diagnoses my body condition. Even a trip out of need”has a medical significance - the toilet does tests. At the same time, my home is a closed cycle: there is nothing superfluous, and nothing is wasted. We have long forgotten the concept of "scum". After all, humanity has gained complete control over the atomic structure of matter. I have everything, but I am spared the shopping trip. Everything I need is provided by nanorobots that disassemble any substance into molecules, be it rubbish, stones or dirt, and collect whatever you want from them: clothes, food, household appliances, even jewelry made of precious metals. With the development of nanotechnology, agriculture, industry, and mining have become useless.
The cities of the future will consist of a swarm of nanorobots and will be able to change their appearance in an instant.
My home, like the furniture in it, is able to take any shape I want. It consists of clusters of programmed nanorobots that can rearrange themselves into essential items. Thanks to the swarm of nanorobots, entire cities can appear and disappear in an instant. Remember the old Terminator 2 movie with a liquid metal robot? It's not fantasy anymore!
Domestic Neanderthal with Pavarotti's voice
I have a glowing cat. I like talking to her and listening to her sing. My home is guarded by a mini dinosaur. Breeders have reached such heights that pet lovers have microdogs, glowing cats, parrots with celebrity voices and aquarium fish spawning gourmet caviar. As for wildlife, scientists have long ago recovered and cloned most of the previously exterminated animal species. Even mammoths and dinosaurs have risen. By the way, back in 2011, geneticists announced that they were about to have the opportunity to recreate a Neanderthal man - they almost deciphered its genome. "From a technical and theoretical point of view, anything is possible," Robert Lanza of Advanced Cell Technology Corporation told reporters in an interview. Only the ethical issue of this act can stop the resurrection of an ancient man."
We have long found a common language with our planetary neighbors. Since the beginning of the 20th century, scientists have worked to create devices that can transform the emotions and thoughts of animals into speech. At first, contacts with primates became possible, then with other mammals, and gradually people learned to communicate even with fish and insects.
On vacation to aliens
Ask what I ride to work? And why should I go there at all, because I work perfectly at home: I sit in a special chair, and thanks to the lenses described above, all the working information is in front of my eyes. We have long forgotten what offices are. We see our colleagues exclusively in virtual reality. If I still need to leave the house, I get into the car. True, I am more of a passenger than a driver, because the robot takes control entirely. But accidents are extremely rare for our era. As you probably guessed, oil reserves have long been exhausted, and transport operates on alternative and environmentally friendly energy sources. I rest in space clubs, of which many have opened in orbit. On vacation I fly to the moon or Mars. Although you can stay with aliens,with whom mankind has long been in touch and established warm relations.
… Of course, someone will say that everything said is on the verge of fantasy. Believe me, this is how not only science fiction writers see the future of the Earth, but also many scientists. After all, while you are reading these lines, they are already trying to bring to life most of the described miracles. So, quite possibly, an even more fantastic world awaits our children and grandchildren.
