Sergey Brin admitted at Stanford University in late December 2025 that his 2019 retirement was a disaster. “I actually retired like a month before Covid hit, and it was the worst decision,” the Google co-founder revealed. During nearly four years away, he described himself as “spiraling” and “not being sharp.” The technical work pulled him back in 2023 to Google’s Gemini AI project, where he now works 3-4 days per week. Staying retired, he insists, “would’ve been a big mistake.”
This matters because it challenges tech’s FIRE narrative with a billionaire cautionary tale. With a net worth around $120 billion, Brin’s failure wasn’t financial—it was existential.
What “Spiraling” Actually Meant
Brin planned to spend retirement studying physics in cafés. However, the reality hit differently. He felt cognitively dulled, lacking the technical creative outlet he’d thrived on for decades. Retiring in December 2019 meant one month of café physics before COVID lockdowns trapped him in isolation. No Google offices. No researchers. No technical problems demanding solutions.
Here’s the uncomfortable truth: some personalities need technical work to stay sharp. Not as a job or for money, but as cognitive exercise and purpose combined. Moreover, when Brin says staying retired “would’ve been a big mistake,” he’s validating every developer who can’t imagine stepping away from code.
The 60-Hour Week Controversy
Brin’s return came with strings attached. A February 2025 leaked memo to Google’s Gemini AI team advocated 60-hour work weeks as the “sweet spot of productivity” and daily office attendance. Google’s official policy requires 3 days in-office. Nevertheless, Brin wants 5+ days and 60-hour weeks, justified by “the final race to AGI.”
The irony isn’t lost on developers. As Futurism put it: “Google Cofounder Exhorts Employees to Work 60-Hour Weeks to Create AI Designed to Replace Them.” Consequently, building your own replacement while sacrificing work-life balance encapsulates the AI era’s absurdity.
Brin’s billionaire perspective makes this tone-deaf. He chose to return because he loved it. His employees face layoffs, ageism, and economic uncertainty. Therefore, telling them to embrace 60-hour weeks feels disconnected from developer reality.
A Pattern of Founder Returns
Brin joins Steve Jobs (left Apple 1985, returned 1997), Jack Dorsey (returned as Twitter CEO 2015), and Michael Dell (returned 2007). Furthermore, research shows 50-year-old founders are twice as likely to succeed as 30-year-olds—experience and technical depth often trump youthful energy, especially for complex AI systems.
What pulled Brin back wasn’t advisory roles but hands-on Gemini development. In fact, the AI arms race provided urgency and the technical creative outlet he’d been missing. For founders who built transformative companies, advisory boards don’t scratch the same itch.
What This Means for Developers
Brin’s story exposes a paradox: he validates “work as purpose” while advocating 60-hour weeks that burn workers out. Additionally, his experience suggests some personalities need technical work to stay cognitively sharp. But with a $120 billion net worth, he chose to return. Most developers don’t have that choice.
The questions his unretirement raises matter: Is work your identity or just a paycheck? Can you retire from something you love building? If technical work provides your primary purpose, does early retirement become spiraling?
Here’s the uncomfortable reality: Brin’s pattern—Jobs, Dorsey, Dell—shows founders in their 50s often return because they’re bored, not burned out. Moreover, AI development seems uniquely compelling as a technical challenge. However, while billionaires can choose their work, developers face layoffs, ageism, and jobs they can’t afford to leave.
The takeaway isn’t “never retire.” It’s “know yourself.” If technical work provides cognitive stimulation and purpose, early retirement might fail. Nevertheless, that doesn’t justify accepting 60-hour weeks. The challenge is finding work that provides purpose without consuming your life.
Brin chose to return. In contrast, most developers are fighting to stay employed or trapped in roles they can’t escape. That difference matters more than any inspirational unretirement story acknowledges.
