Google's Gemini AI hits 1 billion users as company reshuffles leadership to compete with OpenAI

Google's Gemini AI assistant has surpassed 1 billion monthly active users in record time, marking a major consumer milestone. However, the achievement comes amid a seismic leadership reshuffle at Google DeepMind.
