Google co-founder Sergey Brin has made another notable public appearance with Googlers, featuring prominently in the launch video for Antigravity, the company’s newly unveiled AI coding tool. His appearance in the promotional video alongside Varun Mohan, co-founder of Windsurf (whose core team Google recently acquired for $2.4 billion), underscores his “full-time” return from retirement to spearhead the tech giant’s critical artificial intelligence (AI) initiatives. The collaboration between Google and the acquired Windsurf team has directly resulted in Antigravity, which is being touted as an “agent-first” development platform representing a significant leap beyond traditional coding assistants.Brin’s active involvement in the Antigravity launch reflects his broader re-engagement with Google. After the launch of Gemini 3-powered Antigravity, a platform designed to autonomously handle complex engineering workflows, social media erupted with praises, calling it ‘Founder mode on’. Memes and post started to pour in praising Brin for helping develop the latest model and tool.Antigravity enables AI agents to independently plan, execute, test and verify sophisticated tasks across multiple environments, including code editors, terminals, and web browsers, without constant human intervention.The launch can be seen as Google’s aggressive push to dominate the AI development tools market, competing directly with platforms like GitHub Copilot and other AI-assisted programming solutions.
Sergey Brin back at Google office
Brin was back at Google office driven by what he describes as the most exciting era in computer science history. The billionaire technologist, who largely stepped away from day-to-day operations in late 2019, has returned to work directly with engineers on the Gemini project.
“It’s been some of the most fun I’ve had in my life, honestly,” Brin said at the All In Summit in Miami. His initial retirement, which began shortly before the COVID-19 pandemic in early 2020, proved short-lived. “I thought, ‘That’s been good. I want to do something else. I want to hang out in cafes and read physics books.’ And then a month later, I was like, ‘That’s not really happening,'” he recalled.Brin’s return has been particularly focused on Google’s pursuit of artificial general intelligence (AGI). Speaking at Google’s I/O developer conference, he declared the company’s ambitious goal.“We fully intend that Gemini will be the very first AGI,” Brin stated, calling on retired computer scientists to rejoin the field. “Honestly, anybody who’s a computer scientist should not be retired right now,” he added. Google CEO Sundar Pichai has confirmed Brin’s active involvement, noting he now works “pretty much every day” with teams on AI projects, particularly assisting with Gemini’s model training.
