Elon Musk invests in a company called neuralink that connects human brain with computers. Musk is working on this from some time so that humans can compete with growing artificial intelligence.
Neuralink is not focused on improving human brain capabilities initially, but will focus on solving dangerous and chronic medical conditions.
These include neural disorders and mental health issues. Once the initial goal achieved, they could go on probing the human computer augmentation.
Musk sees AI as a threat to humanity at large, and he is pursuing this project which could help humans compete with artificial intelligence.
