Нужно написать summary в течение 30минут artificial intelligence will kill our grandchildren computers have become an integral part of our life, and advances in artificial intelligence (ai) are impressive. it is difficult to predict future progress, but if a computer ever became about as good at programming computers as people are, then it could program a copy of itself. this would lead to an exponential rise in intelligence (now often referred to as the singularity). and evolution suggests that a sufficiently powerful ai would probably destroy humanity. one frightening aspect of an intelligence computer is that it could program itself. if man built the machine, and the machine is about as intelligent as man, then the machine must be capable of understanding and thus improving a copy of itself. when the copy is activated it would be slightly smarter than the original, and thus better able to produce a new version of itself that is even smarter. this process is exponential, just like a nuclear chain reaction. at first only small improvements might be made, as the machine is only just capable of making improvements at all. but as it became smarter it would become better and better at becoming smarter. so it could move from being barely intelligent to hyper intelligent in a very short period of time. man's intelligence is intimately tied to his physical body. the brain is very finite, cannot be physically extended or copied, takes many years to develop and when it dies the intelligence dies with it. on the other hand, an artificial intelligence is just software. it can be trivially duplicated, copied to a more powerful computer, or possibly a botnet of computers scattered over the web. it could also adapt and absorb other intelligent software, making any concept of "self" quite hazy. this means that its world view would be very different from man's, and it is difficult to predict how it would behave. there are many doom's day scenarios. bio technologies, nano technologies, global warming, nuclear annihilation. while these might be annoying, they are all within our normal understanding and some of humanity is likely to survive. we also would have at least some time to understand and react to most of them. but intelligence is fundamental to our existence and its onset could be very fast. how do you argue with a much more intelligent opponent?
