OpenAI is bringing Altman back just days after his ouster as well as installing a revamped board that could bring sharper scrutiny to the startup at the heart of the AI boom, but strong support from investors including Microsoft (MSFT.O) may give Altman more leeway to commercialize the technology.

“Sam’s return may put an end to the turmoil on the surface, but there may continue to be deep governance issues,” said Mak Yuen Teen, director of the centre for investor protection at the National University of Singapore Business School.

“Altman seems awfully powerful and it is unclear that any board would be able to oversee him. The danger is the board becomes a rubber stamp,” he said.

OpenAI’s new board will boast more experience at the top level and strong ties to both the U.S. government and Wall Street.
