A tech industry veteran shares his experiences working closely with artificial intelligence, revealing how it’s transforming both his sleep patterns and business strategies.

Garry Tan, CEO and founder of Y Combinator, has long been known for his forward-thinking approach to technology. At the recent South By Southwest (SXSW) festival, he shared an intriguing insight: his current work with artificial intelligence is so compelling that it’s affecting not just his business strategies but also his sleep patterns.

During a candid on-stage interview at SXSW, Tan revealed that he's experiencing what he calls "cyber psychosis," characterized by intense excitement and barely any rest. “I sleep like four hours a night right now,” he admitted to fellow venture capitalist Bill Gurley. This state of hyper-enthusiasm is so profound that it’s making him question his need for stimulants typically used in startup culture.

“Once you try AI, you’ll realize: it's like I was able to recreate my startup that took $10 million in VC capital and 10 people,” Tan explained. “I worked on that for two years, and I even had to take anti-narcoleptics—like modafinil—to stay awake.” Modafinil is a drug commonly used by entrepreneurs who need to maintain high levels of alertness during the early stages of their ventures.

However, with AI agents now in his toolkit, Tan’s excitement has translated into an almost perpetual state of wakefulness. “I don’t need modafinil with this revolution,” he said emphatically. "Like I’m up. I slept at 4 a.m., and woke up at 8 a.m." He added that while he wanted to sleep more, the allure of monitoring his projects kept him awake.

“I’ve got like three different projects going right now," Tan continued, hinting at the complexity and dynamism of modern AI-driven business environments. His enthusiasm is palpable as he describes how these agents are reshaping not just his work but also his personal life.

The Impact on Business Strategies

For Tan, this newfound obsession with AI isn't merely a passing fancy; it's fundamentally altering the way he approaches business strategy. “I think like a third of the CEOs that I know have it as well,” he joked, suggesting that his experience is not unique but rather indicative of a broader trend in tech leadership.

He went on to explain how AI agents are allowing him and other entrepreneurs to manage their projects more efficiently than ever before. “It’s like having 10 people working for you without the overhead,” he said, highlighting the potential cost savings and productivity gains that come with leveraging advanced technology in business operations.

Moreover, Tan believes this shift is not just about efficiency but also about innovation. "The ability to scale and iterate quickly using AI agents could lead to breakthroughs we haven't even imagined yet," he mused. This perspective underscores the transformative potential of artificial intelligence beyond mere automation or cost reduction.

The Broader Implications

While Tan's experience is personal, his insights into how AI is reshaping business strategies have broader implications for the tech industry as a whole. As more companies begin to integrate AI agents into their operations, we can expect significant changes in both corporate culture and economic dynamics.

The question remains: will this newfound obsession with AI lead to genuine innovation or simply exacerbate existing challenges? Only time will tell, but Tan's enthusiasm suggests that the future of business may indeed be intertwined with these intelligent machines.
