These are the technologies that await us in the future after the Internet revolution

Not long ago, computers were so large that they took up an entire room. They are now everywhere and many are invisible as they are embedded in watches, car engines, cameras, televisions or toys. They manage electrical networks, analyze scientific data and predict the weather. The modern world would be unthinkable without them.

Along with the evolution of computers, the great revolution of our time was born: the Internet . Everything is online and our lives would be much more difficult without it. It is undoubtedly the great invention of the 20th century. But as technology continues to advance, what lies ahead? Here we reveal some of the technologies that await us in the future :

quantum computers

Computers, for the most part, speak the language of bits. They store information, whether it’s music, an app, or a password, in strings of ones and zeros. They also process information in a binary fashion, switching the transistors between an “on” and “off” state. The more transistors there are in a computer, the faster it can process bits, making everything virtual possible, from the most realistic video games to safer air traffic control.

Some types of accelerators could one day use quantum computing , which takes advantage of two features of the subatomic realm. The first is superposition, in which particles can exist not just in one state or another, but in a combination of states. So a quantum system represents information not as bits but as qubits, which can preserve the possibility of being both a zero and a one.

Technology that recycles bits

The second paradigm is reversible computing, in which bits are reused instead of being expelled as heat. But in reversible computing, logic gates have as many outputs as inputs. This means that if you run the logic gate backwards, three output bits could be used to get the three input bits. Some researchers have devised reversible logic gates and circuits that could not only save those extra output bits but also recycle them for other calculations.

Robots almost like humans

Since the earliest days of computing, researchers have set out to replicate human thought. The term “artificial intelligence” attempts to make machines use language, form abstractions and concepts, solve kinds of problems now reserved only for humans, and improve themselves. More than six decades and later, it is not clear if the advances are up to what they had in the beginning.

Artificial intelligence all around us today (from spam filters to humanoid robots) are limited forms of artificial intelligence, performing one or two tasks well, but not capable of autonomous thought. What Allan Turing and other scientists had in mind is called artificial general intelligence, or AGI. Depending on your definition, it’s basically about a machine being able to do most of what humans do, with no difference.
