On July 19, Elon Musk, CEO of Tesla, said that he had uploaded his brain to the cloud and talked with the virtual version of himself. Dogecoin Doge / USD founder Billy Marcus tweeted, "if you can upload your brain to the cloud and talk to your virtual version, will you become friends?" Musk replied, "I have already done it", but musk did not give a detailed introduction. It home learned that musk may be referring to his neural technology company neuralink, which is committed to developing a brain computer interface. The device will allow computers to turn a person's thoughts into actions, allowing them to complete typing and other actions only by thinking. Earlier this year, Fortune magazine reported that according to musk, these devices will allow information to be transmitted back to the brain from the computer. Neuralink has not been approved by the U.S. Food and drug administration, but musk has previously said that the company plans to start implanting computer chips into the human brain by 2022. Musk also said that the device is very important for humans to figure out how to coexist with advanced artificial intelligence. (Xinhua News Agency)
