Elon Musk says that he is going to start a new company called "Neuralink" that will make Humans merge with Computers strictly for cognitive and neural improvements, which can give humans an overall edge over AI , incase the latter tries to exterminate Human Beings.
Elon Musk has already donated over 10 Million Dollars to the purpose of developing AI with the safety of AI not going out of hand and ensuring the AI development is ethical and not a bane to Man Kind.
