Crypto investment should more closely follow adoption patterns in emerging markets.
If the vote is approved and the ETP goes ahead, Floki DAO will join Dogecoin as the second memecoin to have a registered ETP.
Riding political shifts, regulatory optimism and growing institutional interest, these three coins delivered monumental gains this past year.
As we run, drive, bike, and fly, we leave behind telltale marks of our movements on Earth—if you know where to look. Physical tracks, thermal signatures, and chemical traces can reveal where we’ve been. But another type of trail we leave comes from the radio signals emitted by the cars, planes, trains, and boats we use.
On airplanes, technology called ADS-B (Automatic Dependent Surveillance–Broadcast) provides real-time location, identification, speed, and orientation data. For ships at sea, that function is performed by the AIS (Automatic Identification System).
Operating at 161.975 and 162.025 megahertz, AIS transmitters broadcast a ship’s identification number, name, call sign, length and beam, type, and antenna location every six minutes. Ship location, position time stamp, and direction are transmitted more frequently. The primary purpose of AIS is maritime safety—it helps prevent collisions, assists in rescues, and provides insight into the impact of ship traffic on marine life. US Coast Guard regulations say that generally, private boats under 65 feet in length are not required to use AIS, but most commercial vessels are. Unlike ADS-B in planes, AIS can be turned off only in rare circumstances.
A variety of sectors use AIS data for many different applications, including monitoring ship traffic to avoid disruption of undersea internet cables, identifying whale strikes, and studying the footprint of underwater noise.
Using the US National Oceanic and Atmospheric Association’s Marine Cadastre tool, you can download 16 years of detailed daily ship movements, as well as “transit count” maps generated from a year’s worth of data showing each ship’s accumulated paths. The data is collected entirely from ground-based stations along the US coasts.
I downloaded all of 2023’s transit count maps and loaded them up in geographic information system software called QGIS to visualize this year of marine traffic.
The maps are abstract and electric. With landmasses removed, the ship traces resemble long-exposure photos of sparklers, high-energy particle collisions, or strands of fiber-optic wire.




Zooming in on these maps, you might see strange geometric patterns of perfect circles, or lines in a grid. Some of these are fishing grounds, others are scientific surveys mapping the seafloor, and others represent boats going to and from offshore oil rigs, especially off Louisiana’s gulf coast.
Hiding in plain sight
Having a global, near-real-time system for tracking the precise movements of all ships at sea sounds like a great innovation—unless you’re trying to keep your ships’ movements and cargoes secret.
In 2023, Bloomberg investigated how Russia evaded sanctions on its oil exports after the invasion of Ukraine by “spoofing”—transmitting fake AIS data—to mislead observers. Tracking a fleet of rusting ships of questionable seaworthiness, reporters compared AIS data with what they actually saw on the sea—and discovered that the ships weren’t where the data said they were.
Monitoring the fishing industry
Clusters of fishing vessels gravitating toward known fishing grounds create some of the most interesting patterns on the maps.
Global Fishing Watch is an international nonprofit that uses AIS to monitor the fishing industry, seeking to protect marine life from overfishing. But it says that only 2% of fishing vessels use AIS transmitters.
The organization, which is backed by Google, the ocean conservation group Oceana, and the satellite imagery company SkyTruth, combines AIS data with satellite imagery and uses machine learning to classify the types of fishing technology being used.
In a press release announcing the creation of Global Fishing Watch, John Amos, the president and founder of SkyTruth, said: “So much of what happens out on the high seas is invisible, and that has been a huge barrier to understanding and showing the world what’s at stake for the ocean.”

The Worst Technology Failures of 2024
MIT Technology Review publishes an annual list of the worst technologies of the year—chronicling flops, failures, and other mishaps. The 2024 list was unveiled in December by executive editor Niall Firth and senior editor for biomedicine Antonio Regalado. They had a lively discussion about each of the eight items on this list—and what we can learn from these fiascos.
What’s Next for Mixed Reality: Glasses, Goggles, and More
This year brought many new developments in one particular consumer device category: smart glasses. After years of development, new augmented-reality specs from several companies made their debut. Editor in chief Mat Honan and AI hardware reporter James O’Donnell talked about where it’s all heading.
Putting AI’s Climate Impact into Perspective
The rise of AI comes with a growing carbon footprint and greater demand for electricity. Analysts project that AI could drive up data centers’ energy consumption by 160% this decade. So how worried should we be? Editor at large David Rotman, senior AI reporter Melissa Heikkilä, and senior editor for energy James Temple explored the energy trade-offs involved in AI.
CRISPR Babies: Six years later
Gene editing can correct or improve the DNA of human embryos, potentially opening the door to the “technological evolution” of our species. But in 2018, a premature attempt to use the technology this way led to a prison term for He Jiankui, the researcher involved. Editor in chief Mat Honan and senior editor for biomedicine Antonio Regalado had a conversation with He, a biophysicist and the creator of the first gene-edited humans, to revisit this controversial technology and the future of editing in IVF clinics.
Why Thermal Batteries Are So Hot Right Now
Thermal batteries could be a key part of cleaning up heavy industry. Executive editor Amy Nordrum and senior climate reporter Casey Crownhart told us what we can expect next from this emerging technology—which was also voted the 11th breakthrough technology of 2024 by our readers.
Ethereum’s relative strength to Bitcoin could climb in January, which an analyst says might trigger an Ethereum “altcoin run.”
ZachXBT says a hacker has breached 15 crypto-focused X accounts to share scam memecoins that have netted the attacker around $500,000.
Another year is coming to a close, so let’s look back at the MIT Technology Review stories that resonated most with you, our readers.
We published hundreds of stories in 2024, about AI, climate tech, biotech, robotics, space, and more. There were six new issues of our magazine, on themes including food, play, and hidden worlds. We launched two newsletters, to share tech industry analysis from our editor in chief and to step people through the basics of AI. And we hosted 11 exclusive conversations with our editors and experts in our subscriber-only event series, Roundtables.
What did people enjoy most? Here’s a quick look at some of the stories that performed best with our audience:
10 Breakthrough Technologies of 2024
Every year as we compile this annual list, we look for promising technologies poised to have a real impact on the world. It represents the advances that we think matter most, and the 2024 edition included weight-loss drugs, chiplets, and the first gene-editing treatment.
The 2025 list is dropping in early January. To find out what made the cut, join us for a special live Roundtables event, “Unveiling the 10 Breakthrough Technologies of 2025,” on Friday, January 3, at 12:30 p.m. ET. This is a subscriber-only event. Register to attend or subscribe for access.)
Everyone thinks they know, but no one can agree. Senior editor Will Douglas Heaven explored the problem in this in-depth feature story—and explained why it matters for all of our futures. He covers the origins of modern AI and digs into the ongoing debate among experts about this technology’s capabilities and potential.
There’s no denying AI moves fast, and it can be hard to know what’s worth your attention. That’s why we started plotting everything you need to know about the state of AI in a new matrix, along axes that run from “Hype” to “Real” and “Doom” to “Utopia.”
Major tech companies are now developing AI tools that can do more complex tasks, like sending emails or booking plane tickets, on your behalf. Here’s how they will work.

Here’s a question. Imagine that, for $15,000, you could purchase a robot to pitch in with all the mundane tasks in your household. The catch (aside from the price tag) is that for 80% of those tasks, the robot’s AI training isn’t good enough for it to act on its own. Instead, it’s aided by a remote assistant working from the Philippines to help it navigate your home and clear your table or put away groceries. Would you want one?
That’s the question at the center of my story for our magazine, published online today, on whether we will trust humanoid robots enough to welcome them into our most private spaces, particularly if they’re part of an asymmetric labor arrangement in which workers in low-wage countries perform physical tasks for us in our homes through robot interfaces. In the piece, I wrote about one robotics company called Prosper and its massive effort—bringing in former Pixar designers and professional butlers—to design a trustworthy household robot named Alfie. It’s quite a ride. Read the story here.
There’s one larger question that the story raises, though, about just how profound a shift in labor dynamics robotics could bring in the coming years.
For decades, robots have found success on assembly lines and in other somewhat predictable environments. Then, in the last couple of years, robots started being able to learn tasks more quickly thanks to AI, and that has broadened their applications to tasks in more chaotic settings, like picking orders in warehouses. But a growing number of well-funded companies are pushing for an even more monumental shift.
Prosper and others are betting that they don’t have to build a perfect robot that can do everything on its own. Instead, they can build one that’s pretty good, but receives help from remote operators anywhere in the world. If that works well enough, they’re hoping to bring robots into jobs that most of us would have guessed couldn’t be automated: the work of hotel housekeepers, care providers in hospitals, or domestic help. “Almost any indoor physical labor” is on the table, Prosper’s founder and CEO, Shariq Hashme, told me.
Until now, we’ve mostly thought about automation and outsourcing as two separate forces that can affect the labor market. Jobs might be outsourced overseas or lost to automation, but not both. A job that couldn’t be sent offshore and could not yet be fully automated by machines, like cleaning a hotel room, wasn’t going anywhere. Now, advancements in robotics are promising that employers can outsource such a job to low-wage countries without needing the technology to fully automate it.
It’s a tall order, to be clear. Robots, as advanced as they’ve gotten, may find it difficult to move around complex environments like hotels and hospitals, even with assistance. That will take years to change. However, robots will only get more nimble, as will the systems that enable them to be controlled from halfway around the world. Eventually, the bets made by these companies may pay off.
What would that mean? One, the labor movement’s battle with AI—which this year has focused its attention on automation at ports and generative AI’s theft of artists’ work—will have a whole new battle to fight. It won’t just be dock workers, delivery drivers, and actors seeking contracts to protect their jobs from automation—it will be hospitality and domestic workers too, along with many others.
Second, our expectations of privacy would radically shift. People buying those hypothetical household robots would have to be comfortable with the idea that someone that they have never met is seeing their dirty laundry—literally and figuratively.
Some of those changes might happen sooner rather than later. For robots to learn how to navigate places effectively, they need training data, and this year has already seen a race to collect new data sets to help them learn. To achieve their ambitions for teleoperated robots, companies will expand their search for training data to hospitals, workplaces, hotels, and more.

Deeper Learning
This is where the data to build AI comes from
AI developers often don’t really know or share much about the sources of the data they are using, and the Data Provenance Initiative, a group of over 50 researchers from both academia and industry, wanted to fix that. They dug into 4,000 public data sets spanning over 600 languages, 67 countries, and three decades to understand what’s feeding today’s top AI models, and how that will affect the rest of us.
Why it matters: AI is being incorporated into everything, and what goes into the AI models determines what comes out. However, the team found that AI’s data practices risk concentrating power overwhelmingly in the hands of a few dominant technology companies, a shift from how AI models were being trained just a decade ago. Over 90% of the data sets that the researchers analyzed came from Europe and North America, and over 70% of data for both speech and image data sets comes from YouTube. This concentration means that AI models are unlikely to “capture all the nuances of humanity and all the ways that we exist,” says Sara Hooker, a researcher involved in the project.
