Tech billionaire Elon Musk is leaving the board of OpenAI, the nonprofit research group he co-founded with Y Combinator president Sam Altman to study the ethics and safety of artificial intelligence.

The move was announced in a short blog post, explaining that Musk is leaving in order to avoid a conflict of interest between OpenAI’s work and the machine learning research done by Telsa to develop autonomous driving. “As Tesla continues to become more focused on AI, this will eliminate a potential future conflict for Elon,” says the post. Musk will stay on as a donator to OpenAI and will continue to advise the group.
