Sam Rutherford, Karissa Bell and Devindra Hardawar for Engadget As we wrap up 2025, we’re looking at the year’s biggest winners: the people, companies, products and trends that made the most impact over the year. Almost at the top of the pile, of course, are the tech billionaires. According to a recent report by Oxfam, the 10 richest US billionaires (who are all tech leaders, save for Warren Buffet) increased their wealth by $698 billion in 2025. Some of that has been spent treating and lavishing donations on President Trump. Elon Musk reportedly donated nearly $300 million to Trump and Republican allies, and several tech companies have pitched in to build the president’s White House ballroom.

It’s not only overtaken your Facebook and Instagram recommendations, but Meta created an entirely separate feed just for users’ AI-generated fever dreams. The numbers are huge: OpenAI’s Sora, which lets you make AI videos of real people, was downloaded a million times in just a few days. And Google’s Veo generated more than 40 million videos in a few weeks of launching. AI slop is here to stay, and it’s everywhere. Advertisement
