But when COVID hit soon after, he realized he may have made a mistake.

“That didn’t work because there were no more cafés,” he told students at Stanford University’s School of Engineering centennial celebration last week, Business Insider reported.

The transition from president of Google parent company Alphabet to a 40-something retiree ended up not being as smooth as he imagined, and soon after he said he was “spiraling” and “kind of not being sharp” as he stepped away from busy corporate life.

Therefore, when Google began allowing small numbers of employees back into the office, Brin tagged along and put his efforts into what would become Google’s AI model, Gemini. Despite being the world’s fourth-richest man with a net worth of $247 billion, retirement wasn’t for him, he said.

“To be able to have that technical creative outlet, I think that’s very rewarding,” Brin said. “If I’d stayed retired, I think that would’ve been a big mistake.”

By 2023, Brin was back to work in a big way, visiting the company’s office three to four times a week, the Wall Street Journalreported, working with researchers and holding weekly discussions with Google employees about new AI research. He also reportedly had a hand in some personnel decisions, like hiring. 

Skip forward to 2025 and Brin’s plans for a peaceful retirement of quiet study are out the window. In February, he made waves for an internal memo in which, despite Google’s three-day in-office policy, he recommended Google employees go into the company’s Mountain View, Calif. offices at least every weekday, and that 60 hours a week was the “sweet spot” of productivity.

Brin’s newfound efforts at work may have been necessary as OpenAI’s release of ChatGPT in 2022 caught the tech giant off guard, after it had led the field of AI research with DeepMind and Google Brain for years.

To be sure, Google for its part has been rising in the AI race. Analysts raved last month about Gemini 3, the company’s latest update to its LLM, and Google’s stock is up about 8% since its release. Meanwhile, OpenAI earlier this month declared a “code red,” its highest alert level, to improve ChatGPT. 

Brin added in the talk at Stanford that Google has an advantage in the AI arms race precisely because of the foundation it laid over years through its neural network research, its custom AI chips, and its data center infrastructure.

“Very few have that scale,” he said.

“Quite often we are struck that the graduates [who] join us—who are meeting all the cognitive tests we’ve set—they don’t always have the resilience,” Phillippa O’Connor, chief people officer at PwC U.K., recently toldThe Sunday Times. “They don’t always have the human skills that we want to deploy onto the client work we pass them towards.”

“We’ve really doubled down, particularly [with] this year’s graduates,” O’Connor continued. “We’re doing a whole load of separate training in their first six months with us, really about resilience, really about some of those communication skills.”

The executive described resilience as the ability to handle day-to-day work dynamics—especially pressure, criticism, or sticky situations. That skill, she said, is particularly crucial in a deal-making environment, where managing challenges is a “core” part of the job.

According to O’Connor, many younger workers simply didn’t get the chance to build that muscle during the pandemic, when lockdowns disrupted education and early workplace experiences that would normally help develop it.

But by offering this special training, PwC is ensuring the talent that fills its 1,300 open U.K. graduate jobs this year—which received around 47,000 applications—are well-equipped to succeed. 

Fortune reached out to PwC for comment. 

Companies are offering Gen Z special training 

PwC’s “resilience” training is just one example of how employers have been stepping up to ensure Gen Z is primed to succeed in the workforce. 

In 2023, fellow “Big Four” consulting giant KPMGsupplied extra instruction to its Gen Z hires. The business provided training for its graduate talent, out of concern they were struggling to adapt to professional life—particualry when it came to “soft skills,” how to give presentations, work in a team, and manage projects. 

The chief people officer of $1.5 billion data protection start-up Cohesity, Rebecca Adams, has also pushed for inter-generational cohesiveness. 

Earlier this year the executive led the charge to skill bosses in managing the young professionals, citing that Gen Z responds to feedback differently: “They want to know why, how—they want constant feedback.” On the flipside, she described having to teach “basic things” to young staffers that would mind-boggle their Gen X counterparts. 

“How do I manage my calendar? You actually have to accept the meeting request,” Adams explained toFortune in September. “You can’t just walk out of the meeting that you’re in because you have another one while it’s still going on.”

Charitable organizations are also stepping up to solve Gen Z’s professional pitfalls. Radical Hope is a nonprofit helping equip college students with essential skills including communication, interpersonal dexterity, and emotional intelligence. It began as a pilot program at New York University back in 2020, after experts noted “elevated anxiety, stress, and depression” among students within the previous years—and has spread to 75 college campuses so far.  

Liz Feld, the CEO of Radical Hope, hopes the Gen Z trainees will become adept in the skills “we all got growing up at the kitchen table.” Even the little things, like small talk, can be a challenge for the young hopefuls striving to one day succeed in the workplace. 

“They won’t ask someone, ‘Do you want to go to the dining hall and grab dinner, you want to go grab a beer, you want to go for a walk, you want to get a coffee?’” Feld told Fortune, adding that if someone says “no,” their confidence is crushed. “They internalize the whole thing. The face-to-face rejection is what they’re afraid of.”
