It may seem incredible, but all those things, discoveries and technologies of the future, which will be discussed in this review, already exist. The only thing that hinders the massiveness of their use is the cost. We can only hope that everything will change soon enough. And then our world will become completely different.
1. Growing organs
This has already been done, although the technology is still under development. In a nutshell, stem cells are used.
2. Growing meat
Hunger reigns in many parts of the world, so the possibility of growing meat in a laboratory cannot be understated. At the moment, scientists can already do this, but, unfortunately, this is still too expensive a process for mass production.

3. Ice collection
We are talking about the asteroid belt. There is a limited amount of fresh water on Earth, but the solar system is full of it. At the moment, a similar opportunity is being developed by NASA.
4. Thermonuclear reaction
Unlike the fission reaction of atoms, the fusion reaction is much cleaner and much more powerful. This is how stars generate energy. When humanity can finally use thermonuclear fusion, oil will no longer be needed.
5. Superintelligence
On the one hand, it's pretty scary, especially if you remember about SkyNet. But machines are already actually beginning to learn (i.e. reprogram themselves on their own). One can only guess where this will lead.
6. People "on order"
With gene editing technologies like CRISPR, this has long been possible. In some countries (most likely, it will be China, due to the lack of public backlash against genetic modification), "genetically modified" people will soon begin to be born.
7. Nuclear engine
Basically, the idea is to use nuclear explosions to propel a spacecraft. At the moment, the search for materials for the combustion chamber is underway.
8. Cities floating in the air
They will be possible … on Venus. Although the surface of this planet is extremely inhospitable, at an altitude of about 50 km everything becomes not so bad - here the pressure, temperature and gravity almost coincide with the Earth's perfectly. In fact, in many ways, Venus is a much better place to colonize than Mars.
9. Quantum computing
Simply put, computers will be incredibly powerful. The reason for this is that quantum computing will enable algorithms that can potentially solve problems faster. Particles at the quantum level do not follow the rules of physics that everyone takes for granted, since they can inhabit more than one state at a time. Roughly speaking, they will be able to perform several computational operations at the same time.
10. Real dentures
These are prostheses that not only receive signals from the brain (for movement). They will also be able to send signals back (such as touch, temperature and pressure).
11. Artificial brain
This development continues the project of superintelligence and consists in copying the human brain. In a sense, it means downloading consciousness into a computer. Of course, this raises numerous ethical questions, but scientists are now creating a similar technology.
12. Monitors for health
This technology is actually already used in some specific cases, but it basically means the presence of a computer that constantly monitors a person's health and sends information about the condition to a smartphone. Potentially, with the development of technology, a wrist-worn bracelet will be able to diagnose and solve health problems on its own.
13. Solar roads
Similar roads are already being tested in Israel and France. They charge the hybrid cars and electric vehicles that drive over them. If technology develops, there will be no need for gas stations.
14. Unmanned vehicles
It's no secret to anyone that they already exist. In this case, we are talking about a complete transition to such cars. This will dramatically reduce road accidents.
15. Long lasting batteries
Despite all the advances, battery technology is clearly a century behind. So far, only experimental one-off battery development is underway, which will last longer.
BONUS
Augmented reality
Contact lenses may soon offer more than just vision correction. They may be able to provide just about everything that Google Glass does.
