She is also involved with Effective Ventures, an organization focused on effective altruism. Ms. McCauley attended an important A.I. safety summit in Puerto Rico in 2015.

Satya Nadella, the chief executive of Microsoft, played a significant role in the drama surrounding OpenAI. He first met Sam Altman in 2018 at the Sun Valley Conference and, following that encounter, Microsoft agreed to invest $1 billion in OpenAI. Since then, they have invested an additional $12 billion.

Brian Chesky, the chief executive of Airbnb, was another key figure in this tech drama. Mr. Altman was ousted from OpenAI, and Mr. Chesky, a friend and colleague, helped facilitate his return to the company.

Emmett Shear, the former chief executive of Twitch, also played a role in this saga. He founded Justin.tv, which eventually led to the creation of Twitch. Mr. Shear briefly served as OpenAI's interim chief executive.

Lawrence H. Summers, one of the country's most prominent economists, is a new board member for OpenAI. He served as Treasury secretary during the Clinton administration and has been vocal about the potential impact of A.I. on the job market. However, his reputation has been tarnished by controversial statements he made while serving as president of Harvard.

Silicon Valley investor Ron Conway, a longtime friend of Sam Altman, also played a significant role in this tech drama. Alongside Brian Chesky, he helped persuade Altman to fight his way back into OpenAI. Conway even sent a text message to Altman, urging him to put an end to speculation about why he was removed from the OpenAI board.

After Sam Altman's sudden removal and subsequent reinstatement, OpenAI underwent significant changes. A new board was created, with Altman remaining as chief executive. This roller-coaster ride highlighted the heated battle over the future of artificial intelligence in Silicon Valley. Altman's role as a founder of OpenAI, his fundraising efforts, and the involvement of prominent figures such as Satya Nadella and Lawrence H. Summers added to the drama. Ultimately, the turmoil resulted in a reshuffling of OpenAI's leadership and a new chapter for the company.
