India, April 28 -- Elon Musk and Sam Altman will face off this week in a trial that could determine the future of OpenAI. The high-profile showdown between the artificial intelligence titans is the culmination of years of animosity and public feuding over the startup that the pair founded together more than a decade ago, before their relationship soured and they became rivals. Musk alleges Altman and other leaders at OpenAI enriched themselves by abandoning its altruistic principles and converting to a for-profit company with billions of dollars in support from Microsoft Corp. OpenAI and Altman have accused Musk of harassment and say the real goal of the lawsuit is to undercut competition with his own startup that he co-founded in 2023, xAI. The world's richest person is seeking as much as $134 billion in damages from OpenAI and Microsoft-a stratospheric amount for a court case-all of which he pledged just this month to give to OpenAI's charitable arm and not to himself or any of his companies. Musk also is asking the court to remove Altman and OpenAI President Greg Brockman from their leadership positions. But the biggest threat to OpenAI is that Musk is seeking to restore the startup's status as a full nonprofit research organization by unwinding the for-profit restructuring that was completed in October. Altman pitched the conversion as critical to securing the vast amount of funding OpenAI needs to fulfil its mission of creating artificial general intelligence-or AGI-that will benefit humanity. Such a shakeup to OpenAI's C-suite or core structure could destabilise the company during a critical moment as it's eyeing a much-anticipated public offering that could be one of the largest in history; the startup was last valued at $852 billion in March. The brief, failed ouster of Altman in 2023 almost collapsed the ChatGPT maker, with investors pressing the board to bring back Altman and employees pledging to quit en masse if the CEO wasn't reinstated. Another disruption of that magnitude could stymie the company, leaving an opening for rivals to gain ground including xAI, the maker of the Grok chatbot that was recently acquired by SpaceX as Musk's rocket ship company plans an IPO. Microsoft also has a lot on the line, as the restructuring of OpenAI gave the software giant a 27% stake in the startup. Regardless of the outcome, the two years the legal fight has been playing out and the three-week trial amount to a lengthy distraction for OpenAI and its staff at a time when it faces resurgent competition. The trial will revisit years-old questions about OpenAI leaders' actions and whether they upheld their public-interest mission as the company rapidly grew into one of the world's most powerful AI firms....
