Google debuts XR smart glasses with Gemini AI at I/O 2025, backed by Sergey Brin

At Google I/O 2025, Sergey Brin made a notable return to the company spotlight, unveiling a prototype of XR smart glasses integrated with the latest Gemini AI capabilities.

Brin, co-founder of Google, has been deeply involved in training the new Gemini AI models, stating, 'I come into pretty much every day now' to support the development process. His comeback is driven by the need to keep pace with fierce competitors like OpenAI and Perplexity in the rapidly evolving AI landscape.

Highlighting the scale of demand, Brin revealed that Google is expanding its compute resources aggressively but has already had to turn down cloud customers due to capacity constraints. He described the current moment as 'the greatest cusp of technology', emphasizing the unprecedented challenges and opportunities AI presents.

The XR smart glasses demoed at the event showcase how Gemini AI is being embedded into new hardware, signaling Google's push into augmented and extended reality markets. Brin's technical expertise and hands-on involvement underscore the company's commitment to advancing AI capabilities.

"There's just never been a greater, sort of, problem and opportunity  greater cusp of technology," Brin told Big Technology's Alex Kantrowitz during a live interview.

This development marks a significant milestone in Google's AI journey, blending hardware innovation with cutting-edge AI to compete in a high-stakes technological race.
