Elon Musk, the billionaire entrepreneur behind Tesla and SpaceX, has filed a lawsuit against OpenAI and its CEO Sam Altman, accusing them of straying from the company's original mission to develop artificial intelligence for the benefit of humanity. The lawsuit, filed in San Francisco, alleges that Altman and other executives at OpenAI have put profits above the public good, particularly through their partnership with Microsoft. Musk, who helped found OpenAI in 2015, claims that the company's latest AI model, GPT-4, has been kept secret and is now essentially a proprietary algorithm for Microsoft, rather than being made available to the public as originally intended. The lawsuit also accuses Altman of breaching the founding agreement by steering OpenAI towards commercial interests rather than serving the public. Musk is seeking to compel OpenAI to adhere to its original mission and make its AI models open to the public, as well as to repay all the money received from their dealings with Microsoft. This legal action comes at a time of heightened debate over the potential impact of AI, with Musk himself warning of the dangers of unrestricted development of the technology. It also highlights the growing rivalry between OpenAI and Musk's own AI startup, xAI, which is focused on advancing AI technology for the benefit of humanity. The lawsuit underscores the high stakes involved in the race to develop artificial intelligence and the ethical considerations that come with it.
