Google's Gemini has become the 14th Google product to reach 1 billion users, with the company's CEO Sundar Pichai announcing the milestone on social media. Gemini is reportedly Google's fastest-growing product to date. This achievement follows OpenAI's ChatGPT, another AI application that has also reached the 1 billion user mark. While this milestone is significant, it is not the first time an AI app has achieved this level of adoption. The growth of these AI applications highlights the increasing demand for AI-powered services. This matters because it underscores the expanding role of AI in people's daily lives.
