What is really worth your attention in the busy, buzzy world of AI? Our reporters and editors have spent years thinking about this question, charting AI’s progress and mapping out what’s next. Now, for the first time, we’ve distilled our answers into a single list.
The 10 things that matter in AI right now is a brand new look at the big ideas, trends, and new advances in AI that are driving progress or shifting power dynamics today—and will shape what’s possible tomorrow.

On April 17, executives from Zoom, Tinder, and DocuSign went on stage to announce their partnerships with a project called “World,” which verifies that humans are, in fact, humans—and not AI bots.
World, previously known as Worldcoin, is part of Sam Altman’s vision for a world where AI is everywhere—and increasingly hard to tell apart from humans. Of course, the reason that humans may be hard to tell apart from bots is largely because of Sam Altman’s other company: OpenAI.
A few years ago, MIT Technology Review’s investigative reporter, @eileenguo_reports , wrote about Worldcoin. She and a team of reporters across the globe found that the company used questionable tactics to bring in new users, and its chrome orbs collected far more biometric data than the company acknowledged.

After operating in secrecy for years, a startup company called R3 Bio, in Richmond, California, suddenly shared details about its work last week—saying it had raised money to create nonsentient monkey “organ sacks” as an alternative to animal testing. But there is more to the story. And R3 doesn’t want that story told.
MIT Technology Review discovered that the stealth startup’s founder John Schloendorn also pitched a startling, medically graphic, and ethically charged vision for what he's called “brainless clones” to serve the role of backup human bodies.
Imagine it like this: a baby version of yourself with only enough of a brain structure to be alive in case you ever need a new kidney or liver. Or, alternatively, he has speculated, you might one day get your brain placed into a younger clone. That could be a way to gain a second lifespan through a still hypothetical procedure known as a body transplant.
The idea can sound like something straight from a creepy science fiction film. One person who heard R3’s clone presentation, and spoke on the condition of anonymity, was left reeling by its implications and shaken by Schloendorn’s enthusiastic delivery. The briefing, this person said, was like a “close encounter of the third kind” with “Dr. Strangelove.”

The Mars Sample Return mission got off to a promising start, hunting for potentially humanity-changing space rocks. How did it fall off the rails?

The explosion of vehicle transport fraud follows a pattern that has played out across the economy over the past roughly two decades: A business that once ran on phones, faxes, and personal relationships shifted to online marketplaces that increased efficiency and brought down costs—but the reduction in human-to-human interaction introduced security vulnerabilities that allowed organized and often international fraudsters to enter the industry.

In 2024, the Mars Perseverance rover came across an intriguing rock. Instead of the usual crystals or layers of sediment, this one had spots. Two kinds, in fact: one that looked like poppy seeds, and another that resembled those on a leopard. It’s possible that run-of-the-mill chemical reactions could have cooked up these odd features. But on Earth, these marks are almost always produced by microbial life.
To put it plainly: Holy crap.
Sure, those specks are not definitive proof of alien life. But they are the best hint yet that life may not be a one-off event in the cosmos. And they meant the most existential question of all—Are we alone?—might soon be addressed.
But only way to confirm whether these seeds and spots are the fossilized imprint of alien biology is to bring a sample of that rock home to study.
Perseverance was the first stage of an ambitious scheme to do just that—in effect, to pull off a space heist. The mission—called Mars Sample Return and planned by the US, along with its European partners—would send a Rube Goldberg–like series of robotic missions to the planet to capture pristine rocks.
But now, just over a year and a half later, the project is on life support, with zero funding flowing in 2026 and little backing left in Congress. In the race to find evidence of alien life, America has effectively ceded its pole position to its greatest geopolitical rival: China.
