Everyone in AI is talking about Manus. We put it to the test.
Since the general AI agent Manus was launched last week, it has spread online like wildfire. And not just in China, where it was developed by the Wuhan-based startup Butterfly Effect. It’s made its way into the global conversation, with some even dubbing it “the second DeepSeek”.
Manus claims to be the world’s first general AI agent, building off multiple AI models and agents to act autonomously on a wide range of tasks. Despite all the hype, very few people have had a chance to use it. MIT Technology Review was able to obtain access to Manus. Here’s what we made of it.

Waabi says its virtual robotrucks are realistic enough to prove the real ones are safe
The news: Canadian robotruck startup Waabi says its super-realistic virtual simulation is now accurate enough to prove the safety of its driverless big rigs without having to run them for miles on real roads.
How it did it: The company uses a digital twin of its real-world robotrucks, loaded up with real sensor data, and measures how the twin’s performance compares to that of real trucks on real roads. Waabi says they now match almost exactly, and claims its approach is a better way to demonstrate safety than just racking up real-world miles, as many of its competitors do. Read the full story.

This artificial leaf makes hydrocarbons out of carbon dioxide
For many years, researchers have been working to build devices that can mimic photosynthesis—the process by which plants use sunlight and carbon dioxide to make their fuel. These artificial leaves use sunlight to separate water into oxygen and hydrogen, which could then be used to fuel cars or generate electricity. Now a research team from the University of Cambridge has taken aim at creating more energy-dense fuels.
The group’s device produces ethylene and ethane, proving that artificial leaves can create hydrocarbons. The development could offer a cheaper, cleaner way to make fuels, chemicals, and plastics—with the ultimate goal of creating fuels that don’t leave a harmful carbon footprint after they’re burned.

This startup just hit a big milestone for green steel production
Green-steel startup Boston Metal just showed that it has all the ingredients needed to make steel without emitting gobs of greenhouse gases. The company successfully ran its largest reactor yet to make steel, producing over a ton of metal, MIT Technology Review can exclusively report.
The latest milestone means that Boston Metal just got one step closer to commercializing its technology. And while there are still a lot of milestones left before reaching the scale needed to make a dent in the steel industry, the latest run shows that the company can scale up its process.

The big story
Can Afghanistan’s underground “sneakernet” survive the Taliban?
November 2021
When Afghanistan fell to the Taliban, Mohammad Yasin had to make some difficult decisions very quickly. He began erasing some of the sensitive data on his computer and moving the rest onto two of his largest hard drives, which he then wrapped in a layer of plastic and buried underground.
Yasin is what is locally referred to as a “computer kar”: someone who sells digital content by hand in a country where a steady internet connection can be hard to come by, selling everything from movies, music, mobile applications, to iOS updates. And despite the dangers of Taliban rule, the country’s extensive “sneakernet” isn’t planning on shutting down. Read the full story.
