Elon Musk is working on a number of AI-related projects through his companies, including Tesla and OpenAI. One of his most notable projects is Neuralink, a company that is developing a brain-computer interface (BCI) that would allow humans to control computers with their minds. Neuralink is still in the early stages of development, but the potential applications of this technology are significant. Another project that Musk is involved in is Tesla's Autopilot system, which uses AI to enable self-driving cars. This technology has the potential to revolutionize transportation and make driving safer.
