5 desirable technologies the world will never see

3. Mind reading

The most that the so-called “mind reading machines” are capable of is the recognition of images and emotions. Modern technologies are still far from recognizing specific thoughts. Just imagine, there are over 80 billion neurons in the human brain, connected by 40,000 connections. It is incredibly difficult to simulate such a picture, and our thoughts are not static yet. They are distributed throughout the brain. To create such a device would take a huge number of experimental subjects and countless amounts of time.
