Bill Gates warns world leaders are unprepared for AI as jobs vanish, criminals gain power and children lose social skills

Bill Gates has issued his most direct warning yet about artificial intelligence, writing in a new essay that world leaders have no adequate plan for the technology's biggest risks and that without urgent action, the transition to the AI era could cause irreversible damage to employment, public safety and human development.

"AI will either be the greatest equalizer ever invented, or the worst source of injustice," Gates wrote in the essay, shared with Fortune ahead of publication. "The challenge is monumental."

The warning carries particular weight because Gates is not a skeptic of AI. He has repeatedly described himself as an optimist about the technology's potential and has invested billions through the Bill and Melinda Gates Foundation in AI-driven solutions for global health and poverty. That makes his alarm about the world's lack of preparation more striking, not less.

"Unfortunately, right now we are not preparing for it," he wrote. "I don't see evidence that leaders, experts, and communities are confronting the challenges adequately. There is no plan to ease the entry into the AI era."

Gates identified three specific risks he believes are being dangerously underestimated.

The first is permanent job destruction. Gates said many jobs will disappear forever, with entry-level positions the most vulnerable. Customer support roles, software engineering and paralegal work will be among the first to go, he said, while construction and hospitality will shift toward robots by the end of the decade. Both white-collar and blue-collar workers will be affected. The particular concern he raised is for young people entering the workforce, who will find the traditional rungs of the career ladder increasingly absent.

The second risk is criminal empowerment. Gates warned that AI dramatically lowers the barrier to sophisticated fraud, disinformation, deepfakes and surveillance. "Even criminals with very limited skills will be able to target victims at every scale: individuals, companies, and governments," he wrote. The implication is that the same technology making legitimate tasks easier is simultaneously making harmful ones accessible to a far wider pool of bad actors.

The third risk was the most personal. Gates said AI companions risk stunting children's social development by offering frictionless relationships that never challenge or disappoint. Drawing on his own childhood, he wrote that he worked hard to build social skills and make friends, before adding: "I doubt I would have put in the same work if I had had an AI companion back then." He described AI companions as "always available and never mad," attributes that give them the potential to become "highly addictive and to rob us of the lessons we learn from connecting with other people."

Gates did not write only as a critic. He acknowledged that AI holds genuine potential to improve government services, particularly for families navigating complex applications for student assistance, health insurance and food aid. "AI can streamline things dramatically so they get the help they need faster and the government can operate more efficiently," he wrote. The cumulative benefit of that kind of friction reduction, multiplied across millions of lives, could be profound.

But the positive possibilities only sharpen his frustration with the absence of preparation. Gates concluded with a call for governments to build new institutions and frameworks before unemployment rises sharply, communities are hurting and public trust has eroded. He said the questions AI raises are "too consequential to leave to a small group of technologists" and that leaders across academia, business, government and civil society all have a role to play in shaping what comes next.

"I rarely stop thinking about AI, not because I have all the answers, but because the questions it raises are too consequential to leave to a small group of technologists," he wrote.

Gates' net worth is estimated at approximately $108 billion by Forbes, making him one of the world's wealthiest people and a figure whose views on technology carry institutional weight. He co-founded Microsoft in 1975 and stepped back from its day-to-day operations in 2008 to focus on philanthropy. His Gates Foundation has committed more than $60 billion to global health and development since its founding, and he has pledged to give away virtually all of his fortune before he dies.
