[200 Minutes of Entertainment] What will computers look like in 50 years?

I think it is possible to popularize "is brain" after 10, and it is also possible to popularize "is brain" after 50 years! The following is a brief introduction to "yes"

It is a computer composed of optical fibers and various optical elements. Different from ordinary computers, it does not rely on the flow of electrons in the circuit to process information, but relies on a low-power laser to enter the optical path composed of mirrors and lenses for "thinking", but it also has the functions of storage, operation and control.

The size of computer "skills" is mainly determined by two factors: first, the running speed of computer components; The second is how closely they are arranged. From these two aspects, light is much superior to electricity. Photons are the fastest things in the universe, reaching 300,000 kilometers per second. Electrons can't. Their speed of movement in semiconductors is about 60-500 kilometers per second, and the fastest speed is less than one tenth of the speed of light. In addition, in VLSI, some chip devices have more than 300 pins, and the arrangement density is limited. Light beams can cross each other and do not interfere with each other, which enables scientists to open up many information channels in a very small space. For example, the optical converter of Bell Laboratories can be made so small that more than 2,000 channels can be installed in equipment with a diameter less than 2 mm ..

Theoretically speaking, the operation speed of is is thousands of times faster than that of modern computers. Secondly, optical devices also have the advantage of large amount of information. A beam of light can transmit thousands of channels of information at the same time. However, there are still many problems to be solved in theory and technology. As the first step, scientists combine electronic converters with light, and make use of the low driving energy of the optical brain to create a photoelectric hybrid computer.

People may not be familiar with it, but the attempt to make it began in the 1950s, and it was not until the end of 1980s that a decisive breakthrough was made. In the mid-1990s, more than 70 scientists from Britain, France, Belgium, Germany, Italy and other different nationalities successfully developed the world's first is.

So we will use much faster computers in the future, and the current computers will be eliminated in the future!
