>Chatbot answers are all made up. This new tool helps you figure out which ones to trust.

The news: Large language models are famous for their ability to make things up—in fact, it’s what they’re best at. But their inability to tell fact from fiction has left many businesses wondering if using them is worth the risk. A new tool created by Cleanlab, an AI startup spun out of a quantum computing lab at MIT, is designed to give high-stakes users a clearer sense of how trustworthy these models really are.

How it works: The Trustworthy Language Model gives any output generated by a large language model a score between 0 and 1, according to its reliability. This lets people choose which responses to trust and which to throw out. In other words: a BS-o-meter for chatbots.

Why it matters: Cleanlab hopes that its tool will make large language models more attractive to businesses worried about how much stuff they invent. But while the approach could be useful, it’s unlikely to be perfect. Read the full story.

My biotech plants are dead

—Antonio Regalado, MIT Technology Review’s senior biotech editor

Six weeks ago, I pre-ordered the “Firefly Petunia,” a houseplant engineered with genes from bioluminescent fungi so that it glows in the dark.

After years of writing about anti-GMO sentiment in the US and elsewhere, I felt it was time to have some fun with biotech. These plants are among the first direct-to-consumer GM organisms you can buy, and they certainly seem like the coolest.

But when I unboxed my two petunias this week, they were in bad shape, with rotted leaves. And in a day, they were dead crisps. My first attempt to do biotech at home is a total bust, and it cost me $84, shipping included. But, although my petunias have perished, others are having success right out of the box.

This grim but revolutionary DNA technology is changing how we respond to mass disasters

Seven days

No matter who he called—his mother, his father, his brother, his cousins—the phone would just go to voicemail. Cell service was out around Maui as devastating wildfires swept through the Hawaiian island. But as Raven Imperial kept hoping for someone to answer, he couldn’t keep a terrifying thought from sneaking into his mind: What if his family members had perished in the blaze? What if all of them were gone?

Hours passed; then days. All Raven knew at that point was this: there had been a wildfire on August 8, 2023, in Lahaina, where his multigenerational, tight-knit family lived. But from where he was currently based in Northern California, Raven was in the dark. Had his family evacuated? Were they hurt? He watched from afar as horrifying video clips of Front Street burning circulated online.

The list of missing residents meanwhile climbed into the hundreds.

Raven remembers how frightened he felt: “I thought I had lost them.”

Raven had spent his youth in a four-bedroom, two-bathroom, cream-colored home on Kopili Street that had long housed not just his immediate family but also around 10 to 12 renters, since home prices were so high on Maui. When he and his brother, Raphael Jr., were kids, their dad put up a basketball hoop outside where they’d shoot hoops with neighbors. Raphael Jr.’s high school sweetheart, Christine Mariano, later moved in, and when the couple had a son in 2021, they raised him there too.

From the initial news reports and posts, it seemed as if the fire had destroyed the Imperials’ entire neighborhood near the Pioneer Mill Smokestack—a 225-foot-high structure left over from the days of Maui’s sugar plantations, which Raven’s grandfather had worked on as an immigrant from the Philippines in the mid-1900s.

Then, finally, on August 11, a call to Raven’s brother went through. He’d managed to get a cell signal while standing on the beach.

“Is everyone okay?” Raven asked.

“We’re just trying to find Dad,” Raphael Jr. told his brother.

In the three days following the fire, the rest of the family members had slowly found their way back to each other. Raven would learn that most of his immediate family had been separated for 72 hours: Raphael Jr. had been marooned in Kaanapali, 4 miles north of Lahaina; Christine had been stuck in Wailuku, more than 20 miles away; both young parents had been separated from their son, who escaped with Christine’s parents. Raven’s mother, Evelyn, had also been in Kaanapali, though not where Raphael Jr. had been.

But no one was in contact with Rafael Sr. Evelyn had left their home around noon on the day of the fire and headed to work. That was the last time she had seen him. The last time they had spoken was when she called him just after 3 p.m. and asked: “Are you working?” He replied “No,” before the phone abruptly cut off.

“Everybody was found,” Raven says. “Except for my father.”

Within the week, Raven boarded a plane and flew back to Maui. He would keep looking for him, he told himself, for as long as it took.

That same week, Kim Gin was also on a plane to Maui. It would take half a day to get there from Alabama, where she had moved after retiring from the Sacramento County Coroner’s Office in California a year earlier. But Gin, now an independent consultant on death investigations, knew she had something to offer the response

How cuddly robots could change dementia care

This article first appeared in The Checkup, MIT Technology Review’s weekly biotech newsletter. To receive it in your inbox every Thursday, and read articles like this first, sign up here 

Last week, I scoured the internet in search of a robotic dog. I wanted a belated birthday present for my aunt, who was recently diagnosed with Alzheimer’s disease. Studies suggest that having a companion animal can stave off some of the loneliness, anxiety, and agitation that come with Alzheimer’s. My aunt would love a real dog, but she can’t have one.

That’s how I discovered the Golden Pup from Joy for All. It cocks its head. It sports a jaunty red bandana. It barks when you talk. It wags when you touch it. It has a realistic heartbeat. And it’s just one of the many, many robots designed for people with Alzheimer’s and dementia.

This week on The Checkup, join me as I go down a rabbit hole. Let’s look at the prospect of  using robots to change dementia care.

Golden pup robot with red kerchief

As robots go, Golden Pup is decidedly low tech. It retails for $140. For around $6,000 you can opt for Paro, a fluffy robotic baby seal developed in Japan, which can sense touch, light, sound, temperature, and posture. Its manufacturer says it develops its own character, remembering behaviors that led its owner to give it attention.  

Golden Pup and Paro are available now. But researchers are working on much more sophisticated robots for people with cognitive disorders—devices that leverage AI to converse and play games. Researchers from Indiana University Bloomington are tweaking a commercially available robot system called QT to serve people with dementia and Alzheimer’s. The researchers’ two-foot-tall robot looks a little like a toddler in an astronaut suit. Its round white head holds a screen that displays two eyebrows, two eyes, and a mouth that together form a variety of expressions. The robot engages people in conversation, asking AI-generated questions to keep them talking.

The AI model they’re using isn’t perfect, and neither are the robot’s responses. In one awkward conversation, a study participant told the robot that she has a sister. “I’m sorry to hear that,” the robot responded. “How are you doing?”

But as large language models improve—which is happening already—so will the quality of the conversations. When the QT robot made that awkward comment, it was running Open AI’s GPT-3, which was released in 2020. The latest version of that model, GPT-4o, which was released this week, is faster and provides for more seamless conversations. You can interrupt the conversation, and the model will adjust.

The idea of using robots to keep dementia patients engaged and connected isn’t always an easy sell. Some people see it as an abdication of our social responsibilities. And then there are privacy concerns. The best robotic companions are personalized. They collect information about people’s lives, learn their likes and dislikes, and figure out when to approach them. That kind of data collection can be unnerving, not just for patients but also for medical staff. Lillian Hung, creator of the Innovation in Dementia care and Aging (IDEA) lab at the University of British Columbia in Vancouver, Canada, told one reporter about an incident that happened during a focus group at a care facility. She and her colleagues popped out for lunch. When they returned, they found that staff had unplugged the robot and placed a bag over its head. “They were worried it was secretly recording them,” she said.

On the other hand, robots have some advantages over humans in talking to people with dementia. Their attention doesn’t flag. They don’t get annoyed or angry when they have to repeat themselves. They can’t get stressed.

What’s more, there are increasing numbers of people with dementia, and too few people to care for them. According to the latest report from the Alzheimer’s Association, we’re going to need more than a million additional care workers to meet the needs of people living with dementia between 2021 and 2031. That is the largest gap between labor supply and demand for any single occupation in the United States.

Have you been in an understaffed or poorly staffed memory care facility? I have. Patients are often sedated to make them

The Download: cuddly robots to help dementia, and what Daedalus taught us

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

How cuddly robots could change dementia care

Companion animals can stave off some of the loneliness, anxiety, and agitation that come with Alzheimer’s disease, according to studies. Sadly, people with Alzheimer’s aren’t always equipped to look after pets, which can require a lot of care and attention.

Enter cuddly robots. The most famous are Golden Pup, a robotic golden retriever toy that cocks its head, barks and wags its tail, and Paro the seal, which can sense touch, light, sound, temperature, and posture. As robots go they’re decidedly low tech, but they can provide comfort and entertainment to people with Alzheimer’s and dementia.

Now researchers are working on much more sophisticated robots for people with cognitive disorders—devices that leverage AI to converse and play games—that could change the future of dementia care. Read the full story.

What tech learned from Daedalus

Today’s climate-change kraken may have been unleashed by human activity, but reversing course and taming nature’s growing fury seems beyond human means, a quest only mythical heroes could fulfill.

Yet the dream of human-powered flight—of rising over the Mediterranean fueled merely by the strength of mortal limbs—was also the stuff of myths for thousands of years. Until 1988.

That year, in October, MIT Technology Review published the aeronautical engineer John Langford’s account of his mission to retrace the legendary flight of Daedalus, described in an ancient Greek myth. Read about how he got on.
