Human brain is the most valuable creation of God on earth. It is the brain which makes human intelligent and also gives knowledge and stores information. This knowledge or information is destroyed after the death. That knowledge can be useful for society just like the kind of knowledge which Newton or Einstein has could have been very useful for knowledge. So is there any technology which makes it possible. Yes it is possible. IBM is researching to develop an artificial brain that is blue brain. Blue Brain is the world’s first virtual or artificial brain. It is actually not the brain but it just acts like a brain. It means that it is a machine which works just like human brain. It not only thinks like natural brain but also take decisions based on the past experience, and also response like natural brain. Today, scientists are in research to create an artificial brain that can think, response, take decision, and keep anything in memory. The main aim for developing blue brain is to upload human brain into machine. So that after the death of the body, the virtual brain will act as the man .Few hardware and special software’s will be required for blue brain like super computer, very high storage capacity memory to store data, processor for very high processing, wide network. A program to convert the electric impulses from the brain to input signal, which is to be received by the computer, and vice versa and very powerful Nanobots which will act like an interface between the natural human brain and the computer. These nanobots are small robots which are also used for uploading .These robots are small enough to travel throughout our circulatory system.
Even after person’s death his intelligence remains alive.
Things can be remembered easily without much effort.
Allowing deaf to hear via nerve simulation.
Making decisions without the presence of the person.
We become dependent upon the computer.
Some person can use it in an illegal manner.
