Bill Gates had a front-row seat for the rise of AI, from his longtime work at Microsoft to early demonstrations of key breakthroughs from OpenAI that illustrated the technology’s potential. Now he’s urging the rest of us to get ready.
Likening the situation to his pre-COVID warnings about pandemic preparedness, Gates writes in his annual “Year Ahead” letter Friday morning that the world needs to act before AI’s disruptions become unmanageable. But he says that AI’s potential to transform healthcare, climate adaptation, and education remains enormous, if we can navigate the risks.
“There is no upper limit on how intelligent AIs will get or on how good robots will get, and I believe the advances will not plateau before exceeding human levels,” Gates writes.
He acknowledges that missed deadlines for artificial general intelligence, or human-level AI, can “create the impression that these things will never happen.” But he warns against reaching that conclusion, arguing that bigger breakthroughs are coming, even if the timing remains uncertain.
He says he’s still optimistic overall. “As hard as last year was, I don’t believe we will slide back into the Dark Ages,” he writes. “I believe that, within the next decade, we will not only get the world back on track but enter a new era of unprecedented progress.”
But he adds that we’ll need to be “deliberate about how this technology is developed, governed, and deployed” — and that governments, not just markets, will have to lead AI implementation.
More takeaways from the letter:
Job disruption is already here. He says AI makes software developers “at least twice as efficient,” and that disruption is spreading. Warehouse work and phone support are next. He suggests the world use 2026 to prepare, citing the potential for changes like a shorter work week.
Bioterrorism is his top AI concern. Gates warns that “an even greater risk than a naturally caused pandemic is that a non-government group will use open source AI tools to design a bioterrorism weapon.”
Climate will cause “enormous suffering” without action. Gates cautions that if we don’t limit climate change, it will join poverty and infectious disease in hitting the world’s poorest people hardest, and even in the best case, temperatures will keep rising.
Child mortality went backward in 2025. Stepping outside AI, Gates calls this the thing he’s “most upset about.” Deaths for children under 5 years old rose from 4.6 million in 2024 to 4.8 million in 2025, the first increase this century, which he traced to cuts in aid from rich countries.
AI could leapfrog rich-world farming. Gates predicts AI will soon give poor farmers “better advice about weather, prices, crop diseases, and soil than even the richest farmers get today.” The Gates Foundation has committed $1.4 billion to help farmers facing extreme weather.
Gates is using AI for his own health. He says he uses AI “to better understand my own health,” and sees a future where high-quality medical advice is available to every patient and provider around the clock.
AI is now the Gates Foundation’s biggest bet in education. Personalized learning powered by AI is “now the biggest focus of the Gates Foundation’s spending on education.” Gates says he’s seen it working firsthand in New Jersey and believes it will be “game changing” at scale.
