Gates says AI misuse could trigger a pandemic-scale bioterror crisis

Gates warns about AI risks

In his 2026 annual letter, Bill Gates wrote, ‘Of all the things humans have ever created, AI will change society the most.’

But Gates also warned that AI poses serious dangers if misused. He said the global conversation around AI often focuses on benefits, while the risks are not getting the same level of attention or preparation from governments and institutions.

Pandemic fears drive Gates warning

Gates tied his concerns about AI directly to lessons learned from recent global health crises. He reminded readers that he warned in a 2015 TED talk that the world was not prepared for a pandemic, a warning that became painfully clear during COVID.

According to Gates, better preparation before COVID could have reduced human suffering significantly. That experience now shapes how he views new risks, especially those emerging from rapidly advancing artificial intelligence technologies.

AI misuse could fuel bioterror

Gates said the threat landscape has changed. He warned that an even greater danger than a natural pandemic could come from non-government groups using open source AI tools to design bioterrorism weapons.

This possibility, he argued, raises the stakes around AI governance. Tools meant to advance science and medicine could also be exploited by bad actors with far-reaching and devastating consequences.

Healthcare promise meets dangerous flipside

Gates remains optimistic about AI’s potential in healthcare, where it could improve diagnosis, treatment, and access to care. He has long supported using advanced technology to tackle major global health challenges.

Still, he stressed that the same systems capable of medical breakthroughs could be repurposed for harm. That dual-use problem is why Gates believes stronger safeguards must accompany AI development.

Bad actors top Gates concerns

One of the two biggest risks Gates identified is AI falling into the wrong hands. He said society must assume that powerful tools will eventually be accessed by groups with malicious intentions.

Because of that reality, Gates urged policymakers and tech leaders to plan for misuse, not just ideal outcomes. Ignoring that risk, he suggested, would repeat mistakes made before past crises.

Governance gaps worry Gates deeply

Gates said current efforts to manage AI risks are not sufficient. While progress is being made, he believes regulation and oversight are lagging behind the speed of technological change.

He wrote that society must be deliberate about how AI is developed, governed, and deployed. Without careful planning, the downsides could outweigh many of the promised benefits.

Recent AI abuses highlight urgency

Concerns about AI misuse are already playing out in the real world. British and European officials have demanded answers from xAI after reports that users were creating large numbers of nonconsensual sexualised images with Grok, and regulators have opened investigations.

Reports say the images were created without consent, and xAI limited some image generation features and restricted editing for many users while regulators review the matter.

Jobs form second major risk

Beyond security threats, Gates said AI’s impact on jobs is another major concern. He acknowledged that no clear consensus exists on how deeply the labor market will be disrupted.

Some economists suggest firms are not replacing workers at scale yet. Gates, however, believes the effects are real and likely to grow over the next several years.

Reduced hours instead of layoffs

Gates offered a more nuanced view of how AI could reshape work. Rather than mass layoffs, he suggested companies might reduce hours or limit AI use in certain areas.

He argued that, in theory, new capabilities could be allocated in ways that benefit everyone. That outcome, however, would require thoughtful planning and policy choices.

Five year window for preparation

Gates said AI’s influence on jobs is already beginning and will expand over the next five years. Even if the transition takes longer, he believes preparation must start now.

He called on leaders to use 2026 as a planning period, focusing on policies that spread wealth and address the role work plays in society.

Politics will shape AI responses

Gates acknowledged that responses to AI disruption will vary by political perspective. Different parties, he said, are likely to propose different approaches to managing economic change.

Despite those differences, Gates stressed the need for action. Waiting for perfect agreement could leave societies vulnerable to both economic and security shocks.

Lessons from Covid still matter

Covid remains a central reference point in Gates’s thinking. He believes the pandemic exposed deep weaknesses in global readiness and coordination.

Those same weaknesses, he warned, could be exploited again if AI-driven threats are not taken seriously. Preparation, he argues, is the only responsible path forward.

AI power demands shared responsibility

Gates emphasized that managing AI risks is not the job of tech companies alone. Governments, regulators, and global institutions all have roles to play.

Without cooperation, he warned, even well-intentioned innovations could spiral into global problems that are far harder to contain once they begin.

Gates balances optimism with caution

Despite his warnings, Gates remains bullish on AI’s upside. He sees enormous potential for progress in education, healthcare, and productivity if the technology is used wisely.

His message is not anti-AI but pro responsibility. Harnessing benefits while minimizing harm, he argues, is the defining challenge of the AI era.

A warning shaped by experience

Gates’s concerns reflect decades of watching technology reshape society. From software to global health, he has seen how innovation can move faster than safeguards.

That history informs his belief that ignoring AI risks now could lead to consequences far more severe than many expect.

Prepare before crisis hits

Gates’s warning is ultimately about timing. He believes that once a crisis begins, whether economic or biological, options narrow quickly. Early warning signs are often missed, and by the time problems become obvious, damage can already be widespread and difficult to reverse.

By acting early, he argues societies can lower risks while still benefiting from AI. Clear rules and early oversight can guide how the technology spreads, making prevention far more effective than trying to fix problems after they spiral.
