Team Capitalism won. Team Leviathan lost.

OpenAI’s new board will consist of three people, at least initially: Adam D’Angelo, the chief executive of Quora (and the only holdover from the old board); Bret Taylor, a former executive at Facebook and Salesforce; and Lawrence H. Summers, the former Treasury secretary. The board is expected to grow from there.

OpenAI’s largest investor, Microsoft, is also expected to have a larger voice in OpenAI’s governance going forward. That may include a board seat.

Gone from the board are three of the members who pushed for Mr. Altman’s ouster: Ilya Sutskever, OpenAI’s chief scientist (who has since recanted his decision); Helen Toner, a director of strategy at Georgetown University’s Center for Security and Emerging Technology; and Tasha McCauley, an entrepreneur and researcher at the RAND Corporation.

Mr. Sutskever, Ms. Toner and Ms. McCauley are representative of the kinds of people who were heavily involved in thinking about A.I. a decade ago — an eclectic mix of academics, Silicon Valley futurists and computer scientists. They viewed the technology with a mix of fear and awe, and worried about theoretical future events like the “singularity,” a point at which A.I. would outstrip our ability to contain it. Many were affiliated with philosophical groups like the Effective Altruists, a movement that uses data and rationality to make moral decisions, and were persuaded to work in A.I. out of a desire to minimize the technology’s destructive effects.

This was the vibe around A.I. in 2015, when OpenAI was formed as a nonprofit, and it helps explain why the organization kept its convoluted governance structure — which gave the nonprofit board the ability to control the company’s operations and replace its leadership — even after it started a for-profit arm in 2019. At the time, protecting A.I. from the forces of capitalism was viewed by many in the industry as a top priority, one that needed to be enshrined in corporate bylaws and charter documents.
