OpenAI co-founder Elon Musk took to Twitter to defend his early involvement in the company that created ChatCPT, saying it has become a "maximum profit company effectively controlled by Microsoft," which was not what he "intended at all."

The billionaire was responding to a tweet questioning why he co-founded OpenAI when he considers artificial intelligence "one of the biggest risks" to civilization and needs further regulation. 

Musk has long advocated for proactive regulation in the AI space, famously saying in 2018 that the tech has the potential to be more dangerous than nuclear weapons. He said in 2020 that he feared Google's Deepmind could one day effectively takeover the world.

Musk wrote in response: "OpenAI was created as an open source (which is why I named it "Open" AI), non-profit company to serve as a counterweight to Google, but now it has become a closed source, maximum-profit company effectively controlled by Microsoft. Not what I intended at all."
