Where is mankind going?

 Part 3. Коmputer human model

     The developers-programmers create more new games, improving them, more and more. And always they were faced with the question: How do make the game more interesting, more reliable? Can the units be more independent, so that the player is not distracted by care for the detail of each unit? Is it possible to make the units, and grew up umneli yourself, make the right decisions and player would only be watching the game, correct them where necessary, would be for them a caring and wise mentor? That is such a game would be really interesting!
    How can this be achieved? After this each unit, in fact, it is necessary to make such players, not only externally but also in the perception of sensations, the ability to perceive external information, evaluate it, to make decisions. You need to create a scale assessing motivation and actions of each unit, to give them independence, because without independence can never be independent decisions. In fact, it is necessary to teach Unità to think like a man! That is, be simulated on a computer RIGHTS!

    By the way, even more motivation to create a computer model of human soldiers and medics have. They also have greater financial security ...

     But is it possible, in general, to create such a program?
    Why "no"? It is difficult, but possible. We have unraveled the DNA code and the computer can now simulate the result of a combination for a child of different variants of inheritance parents.
We have studied the human body and know now how come and how the nerve channels of information is transmitted to the brain.
We know already, in what area of ​​the brain signals are transmitted on different bodies. Already created artificial sensory organs and limbs controlled by brain. In fact, it is now possible to simulate the human brain, any feelings for him t.e.sozdat any given reality. Inasmuch as it is created artificially, then in fact that reality is virtual. On these principles, in general, and built a variety of gaming devices for computer games. So far, however, gaming is not connected to the electrodes implanted in the brain, but the device to control the computer using the brain impulses are already available commercially.

Thus, the simulation of peripheral sensory input-output external signals can be right now. The difficulty so far is simulation of the human brain - it is not clear how he "thinks" where and how to store information. It turns out that the information is not stored in the brain in a certain place, it is spread out across the cortex, in which the brain is similar to a hologram, where even a small part of the hologram stores information about the whole picture. On these principles are organized holographic sight and hearing.

On clarifying the details of these processes are not running a team of scientists, and there are already first results - computer scientists at IBM in collaboration with scientists from the National Laboratory, Berkeley, Stanford University Medical Center, Columbia University, Madison and the University of California Project Workbench simulation work carried out part of the brain , including one billion neurons and 10 trillion synapses (the volume of the brain of animals). Of course, this is - is just the beginning: for example, the human brain contains 20 billion neurons, connected 200 trillion synapses. But the results are very encouraging, and the IBM predicts that the task of modeling the human brain can be achieved by 2020.

There is one more obstacle in the way of computer simulation of the individual - the very possibility of computer equipment. While the most advanced supercomputers came only petaflopovuyu performance (flops - a unit measuring the speed of computer operations) is - 10 ** 15 (10 at 15th level) operations per second. To simulate the same brain activity of only one person is required by various estimates 10 ** 14 - 10 ** 17 op / sec. This is - a very large quantity.
Now the total computing power of all earthly computers is about 10 ** 18 op / sec. Like, am I missing? Not at all. The fact that the "total power" - is an abstract quantity that characterizes only the level of computerization. As nine women for 1 month may not have one child and one billion computers currently available can not solve the problem of simulation of the nervous system is only one person (for example, even a simulation of normal cat brain, performed within the project mentioned above Workbench on a supercomputer Dawn (platform Blue Gene / P), was carried out almost 100 times slower than in the brain of the real animal).

The head of the Swiss project of computer simulation of the brain Blue Brain (by the way, has some very impressive results) - Henry Markram estimates that for an accurate simulation of a trillion synapses in the human brain, the computer must be able to process about 500 petabytes (1024 terabytes = 50 = 2 degrees bytes ) data. It - approximately 200 times greater than the information that is stored on all servers in Google. Using modern technology, this supercomputer would take several football fields.surprised
Energy consumption - another huge problem. If the human brain in the process consumes only 25 watts of electricity, the process of modeling the brain on a supercomputer with existing microchips requires energy of about 3 billion dollars a year.cry
Blue Brain scientists group believe that if computing technology will continue to grow in the current accelerated rate, and reduced power consumption, they will be able to simulate the human brain is entirely on one machine is ten years or even earlier.

Of course, this forecast is overly optimistic, if the growth of computing power is assumed only by further increasing the number of processors that are connected in parallel. And this forecast may well be real, if in the coming years will create computers based on new physical principles: whether quantum computers, or molecular, or even what ...

With further development of technology and growth opportunities can be created even larger computers, and performance, if necessary, they can even be made in space and occupy an entire planet. Of course, this is a completely different level of technology: the planet-to-computer. A rough estimate of the future of computing power supercomputer with a mass of the planet is 10 ** 42 operations per second, and it is only taking into account the already known nanotechnological solutions, which, of course, far from optimal.
One such machine would be sufficient not only to fully simulate the individual, but also to start the game, which would have simulated the entire history of mankind. And it would require only one millionth of its computing resources.

I'm talking about the game, as the game - this is the most meaningful application of these technologies. But every game - it is also a model of some more serious process ...
