PERSON OF THE YEAR

SINCE 1801, AMERICAN LEADERS HAVE GATHERED in Washington, D.C., to attend the Inauguration of a new President.

It is a day of great tradition, one that often brings together the most powerful people in the country. Prominent at Donald Trump's return to office in January were the chiefs of U.S. technology companies, which long have led the world. But something unexpected was happening offstage: that same day, a little-known Chinese firm called DeepSeek released a new artificial-intelligence model that spooked markets and led to a rallying cry from Silicon Valley.

The next day, tech titans Sam Altman, Larry Ellison, and Masayoshi Son appeared at the White House with an announcement of their own. They pledged to invest up to $500 billion to build AI data centers around the U.S., calling the project Stargate. Those two days foretold the year to come: global competition, astounding innovation, massive sums of money, and the alchemizing forces of public and private interests.

This was the year when artificial intelligence's full potential roared into view, and when it became clear that there will be no turning back or opting out. Whatever the question was, AI was the answer. We saw it accelerate medical research and productivity, and seem to make the impossible possible. It was hard to read or watch anything without being confronted with news about the rapid advancement of a technology and the people driving it. Those stories unleashed a million debates about how disruptive AI would be for our lives. No business leader could talk about the future without invoking the impact of this technological revolution. No parent or teacher could ignore how their teenager or student was using it.
