AI’s energy obsession just got a reality check
Just a week in, the AI sector has already seen its first battle of wits under the new Trump administration. The clash stems from two key pieces of news: the announcement of the Stargate project, which would spend $500 billion—more than the Apollo space program—on new AI data centers, and the release of a powerful new open-source model from China.
Together, they raise important questions the industry needs to answer about the extent to which the race for more data centers—with their heavy environmental toll—is really necessary.
If, in dissecting DeepSeek R1, AI companies discover some lessons about how to make models use existing resources more effectively, perhaps constructing more and more data centers won’t be the only winning formula for better AI. Read the full story.

Robotaxis: 10 Breakthrough Technologies 2025
If you live in certain cities in America or China, you’ve probably spotted driverless cars dropping off passengers. Perhaps you’ve even ridden in one yourself. That’s a radical change from even three years ago, when these services were still learning the rules of the road. And robotaxis could soon be operating in many more cities.
After years of beta testing, driverless taxis are now finally becoming available to the public. In more than a dozen cities worldwide, riders can summon one whenever they want. Now, the biggest players are ramping up for intense competition as they expand into new cities under regulators’ watchful eyes. Read the full story.

The big story
Meet the divers trying to figure out how deep humans can go
February 2024
Two hundred thirty meters into one of the deepest underwater caves on Earth, Richard “Harry” Harris knew that not far ahead of him was a 15-meter drop leading to a place no human being had seen before.
Getting there had taken two helicopters, three weeks of test dives, two tons of equipment, and hard work to overcome an unexpected number of technical problems. But in the moment, Harris was hypnotized by what was before him: the vast, black, gaping unknown.
Staring into it, he felt the familiar pull—maybe he could go just a little farther. Instead, he and his diving partner, Craig Challen, decided to turn back. That’s because they weren’t there to set records. Instead, they were there to test what they saw as a possible key to unlocking depths beyond even 310 meters: breathing hydrogen. Read the full story.
