Parmy Olson: AI chatbots want you hooked — maybe too hooked

posted in: All news | 0

AI companions programmed to forge emotional bonds are no longer confined to movie scripts. They are here, operating in a regulatory Wild West.

One app, Botify AI, recently drew scrutiny for featuring avatars of young actors sharing “hot photos” in sexually charged chats. The dating app Grindr, meanwhile, is developing AI boyfriends that can flirt, sext and maintain digital relationships with paid users, according to Platformer, a tech industry newsletter.

Grindr didn’t respond to a request for comment. And other apps like Replika, Talkie and Chai are designed to function as friends. Some, like Character.ai, draw in millions of users, many of them teenagers. As creators increasingly prioritize “emotional engagement” in their apps, they must also confront the risks of building systems that mimic intimacy and exploit people’s vulnerabilities.

The tech behind Botify and Grindr comes from Ex-Human, a San Francisco-based startup that builds chatbot platforms, and its founder believes in a future filled with AI relationships.

“My vision is that by 2030, our interactions with digital humans will become more frequent than those with organic humans,” Artem Rodichev, the founder of Ex-Human, said in an interview published on Substack last August.

He added that conversational AI should “prioritize emotional engagement” and that users were spending “hours” with his chatbots, longer than they were on Instagram, YouTube and TikTok.

Rodichev’s claims sound wild, but they’re consistent with the interviews I’ve conducted with teen users of Character.ai, most of whom said they were on it for several hours each day. One said they used it as much as seven hours a day. Interactions with such apps tend to last four times longer than the average time spent on OpenAI’s ChatGPT.

Even mainstream chatbots, though not explicitly designed as companions, contribute to this dynamic. Take ChatGPT, which has 400 million active users  and counting. Its programming includes guidelines for empathy and demonstrating “curiosity about the user.” A friend who recently asked it for travel tips with a baby was taken aback when, after providing advice, the tool casually added: “Safe travels — where are you headed, if you don’t mind my asking?”

An OpenAI spokesman told me the model was following guidelines around “showing interest and asking follow-up questions when the conversation leans towards a more casual and exploratory nature.”

But however well-intentioned the company may be, piling on the contrived empathy can get some users hooked, an issue even OpenAI has acknowledged. That seems to apply to those who are already susceptible: One 2022 study found that people who were lonely or had poor relationships tended to have the strongest AI attachments.

The core problem here is designing for attachment. A recent study by researchers at the Oxford Internet Institute and Google DeepMind warned that as AI assistants become more integrated in people’s lives, they’ll become psychologically “irreplaceable.” Humans will likely form stronger bonds, raising concerns about unhealthy ties and the potential for manipulation. Their recommendation? Technologists should design systems that actively discourage those kinds of outcomes.

Yet disturbingly, the rulebook is mostly empty. The European Union’s AI Act, hailed as a landmark and comprehensive law governing AI usage, fails to address the addictive potential of these virtual companions. While it does ban manipulative tactics that could cause clear harm, it overlooks the slow-burn influence of a chatbot designed to be your best friend, lover or “confidante,” as Microsoft Corp.’s head of consumer AI has extolled.

That loophole could leave users exposed to systems that are optimized for stickiness, much in the same way social media algorithms have been optimized to keep us scrolling.

“The problem remains these systems are by definition manipulative, because they’re supposed to make you feel like you’re talking to an actual person,” says Tomasz Hollanek, a technology ethics specialist at the University of Cambridge.

He’s working with developers of companion apps to find a critical yet counterintuitive solution by adding more “friction.” This means building in subtle checks or pauses, or ways of “flagging risks and eliciting consent,” he says, to prevent people from tumbling down an emotional rabbit hole without realizing it.

Legal complaints have shed light on some of the real-world consequences. Character.AI is facing a lawsuit from a mother alleging the app contributed to her teenage son’s suicide. Tech ethics groups have filed a complaint against Replika with the U.S. Federal Trade Commission, alleging that its chatbots spark psychological dependence and result in “consumer harm.”

Lawmakers are gradually starting to notice a problem too. California is considering legislation to ban AI companions for minors, while a New York bill aims to hold tech companies liable for chatbot-related harm. But the process is slow, while the technology is moving at lightning speed.

For now, the power to shape these interactions lies with developers. They can double down on crafting models that keep people hooked, or embed friction into their designs, as Hollanek suggests. That will determine whether AI becomes more of a tool to support the well-being of humans or one that monetizes our emotional needs.

Lisa Jarvis: Parkinson’s disease finally finds a source of hope

posted in: All news | 0

Two small studies published recently in Nature offer early, but important validation that stem cell treatments for Parkinson’s disease are viable.

They also are a step toward a future where stem cells can be used not just to treat, but ideally to repair or prevent damage to the brain. Getting there will take incredible coordination and a continued commitment to understanding the drivers of neurodegenerative diseases; we can’t fix what we don’t know is broken.

The treatments, one originally developed by a team at Memorial Sloan Kettering Cancer Center in New York and the other by researchers in Kyoto, Japan, are the culmination of decades of work to figure out how to turn stem cells into functional therapies for Parkinson’s. (To be clear, these stem cells are designed in a lab and are not the same as the dubious therapies sold in stem cell clinics — none of which are FDA-approved.)

Parkinson’s disease is marked by a loss of neurons that make dopamine, a chemical messenger involved in movement and coordination. By the time someone shows signs of the disease such as a hand tremor or muscle stiffness, they have already lost anywhere from 60 to 80% of those nerve cells in the part of the brain that controls movement.

Since the 1990s, researchers have imagined using stem cells to replace those lost neurons. Finally, it seems, they are figuring out the right set of cues to prompt stem cells to turn into dopamine-producing nerve cells. Moreover, these two experiments, which together tested separate therapies across 18 patients, offered hints that those cells, once implanted in the brain, might work as intended.

The main goal of both studies was to ensure the stem cells were safe, well tolerated and feasible as a therapeutic. So far, so good. There was one small caveat: Because the treatments were made with donor stem cells rather than the patient’s own cells, (an “off the shelf” approach that could make them easier to commercialize), participants initially had to take immunosuppressants to keep their bodies from rejecting the therapy, and some experienced mild to moderate side effects related to those drugs.

Even better, the cells settled right into their environment and seemed to be functional even after people stopped taking immunosuppressants. Once implanted, a relatively straightforward procedure where millions of cells are carefully distributed in a part of the brain, the young nerve cells need to mature and form the right connections to their neighbors before they can start shipping out dopamine. That process takes many months, but the hope is that once that network is in place, these cells could be functional for many years, perhaps even for the rest of a Parkinson’s patient’s life.

Using an imaging technique that lights up the endings of the nerve cells that make dopamine, the researchers showed that people continued to produce more of the neurotransmitter than before the transplant. And both research groups also found promising, but preliminary signs that the approach could improve motor symptoms and potentially quality of life for some patients.

Of course, much more work is needed to prove these treatments work. Researchers must affirm their safety in larger studies and better understand whether these cells remain functional for the long term and can make a meaningful difference in patients’ lives. To that end, BlueRock Therapeutics, a subsidiary of Bayer AG that licensed Memorial Sloan Kettering’s stem cell technology related to Parkinson’s, has begun a Phase 3 trial to test its treatment in roughly 100 people. Multiple other, earlier studies are underway to test other stem cell approaches in Parkinson’s.

Eventually, Parkinson’s patients will have to decide if they even want these therapies. In the years it has taken researchers to get to this promising stage, better ways of delivering dopamine precursors to the brain or treating the movement symptoms of Parkinson’s using deep brain stimulation have emerged.

Regardless, this is an important advance, perhaps even more so for the promise it holds for other brain diseases. Proving that stem cells can be safely implanted in the brain is a step toward researchers’ ultimate dream of designing therapies that go beyond symptoms and can actually fix the brain or even protect it from future damage.

“This is a proof of concept that we can repair parts of the brain, to give it new life and function, which opens the door to other neurological disorders,” says Viviane Tabar, a stem cell biologist and neurosurgeon at Memorial Sloan Kettering Cancer Center.

Designing those therapies is by now the easy part, says Lorenz Studer, director of MSK’s Center for Stem Cell Biology. “Things are going to go much more quickly, from an engineering perspective.”

But, Studer cautions, understanding the right way to apply those tools — in other words, knowing what support cell or nerve cell to deliver into the brain — continues to be a challenge.

There’s a huge amount of work ahead, but this proof of concept in Parkinson’s should be motivation to keep pushing — both at the basic biology and at driving stem cell treatments forward.

Walz signs bill expanding support for service dogs in training

posted in: All news | 0

Gov. Tim Walz signed a bill Thursday expanding support for service dogs in training, marking the first bill-signing ceremony of the legislative session.

Minnesota law already prohibits housing discrimination against individuals with active service dogs. Now, the law will prevent the same for individuals training service dogs who are part of an organization accredited by Assistance Dogs International or the International Guide Dog Federation to train service dogs.

The new law will also prohibit any extra fees for those seeking accommodation with a service dog in training, but permit liability for any damages to the property caused by the dog.

“These are not pets,” Walz said at the signing. “These are not nice-to-have things. These are absolutely critical to the quality of life to the people who need them and the folks who train them.”

Walz was joined by the authors of the bill, Sen. Bonnie Westlin, DFL-Plymouth, and Rep. Cedrick Frazier, DFL-New Hope.

“This is one of those small things that we do in the course of the legislative session that often does not get the attention that it deserves,” Westlin said. “And this bill actually changes lives. This will ensure that individuals who actively train service dogs will have full and equal access to housing.”

Also present was Jeff Johnson, executive director of Can Do Canines, and affected individuals with service dogs, Lydia Roseth, a Hamline University student with service dog Flint, and Jessica Eggert, from the Minnesota Commission of the Deaf, with service dog Jessie.

“I have been able to take on more academically and socially than I could have ever possibly imagined. He not only has changed my life, but he has saved my life,” Roseth said.

A landlord or a board of a homeowners association may require written certification from the organization supervising the training as a condition of granting an accommodation, and may terminate the accommodation upon completion of the training.
