In a significant leadership reshuffle, Google has announced a series of changes within its AI division. Prabhakar Raghavan, the executive overseeing the company's search engine and ads products, is stepping down to take on the role of Chief Technologist. His position will be filled by longtime Google executive Nick Fox.

The move comes as Google continues to invest heavily in AI, seeking to solidify its position as a leader in the field. The company has faced increasing antitrust scrutiny, with lawsuits alleging anti-competitive practices.

"Prabhakar has decided it's time to make a big leap in his own career," Google CEO Sundar Pichai said in a statement. "After 12 years leading teams across Google, he'll return to his computer science roots and take on the role of Chief Technologist."

Raghavan, who has been instrumental in Google's AI initiatives, oversaw the launch of AI features in Gmail, Maps, and Shopping. His departure marks a significant shift for the company.

Nick Fox, who will replace Raghavan, has been involved in shaping Google's AI product roadmap. He has helped launch products like Google Fi and RCS messaging.

Additionally, the Gemini app team, led by Sissie Hsiao, will join Google DeepMind under Demis Hassabis. The Google Assistant team will also become part of Google's platforms and devices team.

These changes are aimed at improving collaboration and streamlining development efforts within Google's AI division. As the company continues to face antitrust challenges, these leadership changes may signal a renewed focus on innovation and competition.
