Sergey Brin Returns to Google: A Focus on AI and Innovation

Google co-founder Sergey Brin has recently returned to the company, expressing his enthusiasm for the advancements in artificial intelligence (AI) and his involvement in training the company’s Gemini models. Brin, who stepped away from his official roles at Alphabet in 2019, has been actively participating in Google’s AI initiatives, particularly in the development of Gemini models, which are central to the company’s AI strategy.

During a surprise appearance at the Google I/O developer conference last week, Brin shared his excitement about the progress being made in AI. He mentioned that he now visits the Google office almost daily to contribute to the training of these models, finding the work both interesting and aligned with his scientific interests. Brin’s return to Google marks a significant shift, as he and co-founder Larry Page had previously retired from their roles in 2019.

Brin’s appearance at the conference was unplanned, as he joined a session initially scheduled for Demis Hassabis, the head of Google DeepMind. Brin joked about his involvement, stating that he enjoys diving into the technical details while Hassabis manages other aspects. This collaboration highlights the synergy between Google and DeepMind, with both entities focusing on pushing the boundaries of AI technology.

One of the key areas Brin is focusing on is the development of wearables, a sector that Google is renewing its efforts in after pausing the Google Glass project a decade ago. Brin expressed optimism about the potential of wearables, acknowledging the challenges in consumer electronics supply chains and achieving affordable price points. However, he believes that advancements in AI have made it possible to overcome these hurdles and create innovative products.

Google is currently working on Extended Reality (XR), an operating system for wearables such as smart glasses. In partnership with companies like Samsung, Google demonstrated an XR-powered smart glasses prototype at the I/O 2025 conference, showcasing the integration of Gemini AI capabilities. This prototype highlights Google’s commitment to advancing wearable technology and integrating AI to enhance user experiences.

Brin’s return to Google is a testament to his passion for technology and innovation. His involvement in training Gemini models and his focus on wearables underscore the company’s renewed commitment to AI and its potential to transform various industries. As Google continues to push the boundaries of AI, Brin’s expertise and vision will play a crucial role in shaping the future of technology.
