Summary:
Sam Altman has returned to the OpenAI board after an investigation into his ouster concluded that there were no valid reasons for removing him from the position. The report also found that the breakdown in trust between Altman and the previous board was the main reason for his removal. This marks a significant shift for OpenAI, as they faced a tumultuous period that nearly led to its collapse. However, with Altman's return and the addition of new board members, the company is expected to move past this challenging phase.
