It has long been suggested that people's thinking knowledge can be uploaded to the cloud, and even if the physical body does not exist, they can gain eternal life. Some professionals pointed out that this matter seems to be a reality in theory. At present, it is limited to theory, and we are far from realizing it. Imagine a simple scan of the human brain, and then a computer can read his memory and consciousness and transmit it to the computer for modeling. After the model is successfully established, the simulation can be realistic. Nowadays, the storage of computer and mobile phone data is often stored in the cloud. According to this idea, the huge data read from the brain can also be stored in the cloud, encrypted with the latest technology, which will not be leaked and can be read at any time when needed.
Neurons in the human brain are very complex, and it is glial cells that support the transmission between neurons, and the existing technology cannot explore the mystery. That is, there are hundreds of millions of neurons in the human brain, and these neurons are supported by a kind of glial cells, but in fact, the composition of glial cells and their relationship with transmission neurons are still unknown. What subtle changes will happen to the connections between neurons when the brain is stimulated by certain external stimuli? Not knowing this shows that people's thinking consciousness can't be copied.
In the dream, everything in the brain can be uploaded to the virtual space. When the body does not exist, it can be transferred to the robot for eternal life. At present, this is just a bold assumption.
