Emmett Shear has been appointed to lead OpenAI, a startup that specializes in advanced artificial intelligence research. This move comes as a replacement for Sam Altman, who will be joining Microsoft to lead a new AI research team. This was announced on Sunday by Microsoft CEO Satya Nadella, who also stated that Microsoft is committed to its partnership with OpenAI.

Shear, who was previously the boss at Twitch, will be taking over the role of interim CEO at OpenAI. This decision not to reinstate Altman as CEO has caused concern among investors and employees, who fear that this abrupt change in leadership could lead to a talent exodus and impact an upcoming $86 billion share sale.

Additionally, Altman and Greg Brockman, who stepped down from the OpenAI board, joined executives at the company’s headquarters after interim CEO Mira Murati invited Altman, according to The Information. Nadella also mentioned that Brockman would be joining Microsoft as well.

After the news of the management change, dozens of employees announced their resignation from OpenAI, leading to a sense of unrest among staff. Some prominent researchers, including Szymon Sidor, have also left the company following the CEO change.

The departure of key leaders and employees has raised concerns about the future of the company, which was known for its generative AI technology, particularly its ChatGPT chatbot. Nonetheless, Microsoft remains committed to supporting OpenAI, as the company forges ahead with its new leadership team.
