OpenAI's new interim CEO, Emmett Shear, is known as an AI 'doomer' who is concerned about the potential risks of AI and its impact on humanity. The abrupt dismissal of former CEO Sam Altman has caused turmoil within OpenAI, with employees expressing their discontent and leading to Altman and co-founder Greg Brockman seeking their next venture at Microsoft. With the leadership of an AI 'doomer' like Shear, the future direction of OpenAI remains uncertain, while Google's AI-centric revamp faces challenges, including the delay of its ChatGPT rival Gemini.
