How to free our kids - and ourselves - from tech addiction, with Gaia Bernstein
In today's podcast episode, law professor Gaia Bernstein talks about the challenges of keeping control over our thoughts and actions, even when some powerful forces are pushing in the other direction.
Each afternoon, kids walk through my neighborhood, on their way back home from school, and almost all of them are walking alone, staring down at their phones. It's a troubling site. This daily parade of the zombie children just can’t bode well for the future.
That’s one reason I felt like Gaia Bernstein’s new book was talking directly to me. A law professor at Seton Hall, Gaia makes a strong argument that people are so addicted to tech at this point, we need some big, system level changes to social media platforms and other addictive technologies, instead of just blaming the individual and expecting them to fix these issues.
Gaia’s book is called Unwired: Gaining Control Over Addictive Technologies. It’s fascinating and I had a chance to talk with her about it for today’s podcast. At its heart, our conversation is really about how and whether we can maintain control over our thoughts and actions, even when some powerful forces are pushing in the other direction.

We discuss the idea that, in certain situations, maybe it's not reasonable to expect that we’ll be able to enjoy personal freedom and autonomy. We also talk about how to be a good parent when it sometimes seems like our kids prefer to be raised by their iPads; so-called educational video games that actually don’t have anything to do with education; the root causes of tech addictions for people of all ages; and what kinds of changes we should be supporting.
Gaia is Seton’s Hall’s Technology, Privacy and Policy Professor of Law, as well as Co-Director of the Institute for Privacy Protection, and Co-Director of the Gibbons Institute of Law Science and Technology. She’s the founding director of the Institute for Privacy Protection. She created and spearheaded the Institute’s nationally recognized Outreach Program, which educated parents and students about technology overuse and privacy.
Professor Bernstein's scholarship has been published in leading law reviews including the law reviews of Vanderbilt, Boston College, Boston University, and U.C. Davis. Her work has been selected to the Stanford-Yale Junior Faculty Forum and received extensive media coverage. Gaia joined Seton Hall's faculty in 2004. Before that, she was a fellow at the Engelberg Center of Innovation Law & Policy and at the Information Law Institute of the New York University School of Law. She holds a J.S.D. from the New York University School of Law, an LL.M. from Harvard Law School, and a J.D. from Boston University.
Gaia’s work on this topic is groundbreaking I hope you’ll listen to the conversation and then consider pre-ordering her new book. It comes out on March 28.
After a Diagnosis, Patients Are Finding Solace—and Empowerment—in a Sensitive Corner of Social Media
Katherine Leon and her dog enjoy nice weather in their backyard in Virginia. Leon went from feeling like she was "wandering in the woods" with doctors who hadn't experienced her spontaneous coronary artery dissection, or SCAD, to starting the world's largest registry for research on the condition.
When Kimberly Richardson of Chicago underwent chemotherapy in 2013 for ovarian cancer, her hip began to hurt. Her doctor assigned six months of physical therapy, but the pain persisted.
She took the mystery to Facebook, where she got 200 comments from cancer survivors all pointing to the same solution: Claritin. Two days after starting the antihistamine, her hip felt fine. Claritin, it turns out, reduces bone marrow swelling, a side effect of a stimulant given after chemo.
Richardson isn't alone in using social media for health. Thirty-six percent of adults with chronic diseases have benefited from health advice on the internet, or know others who have. The trend has likely accelerated during COVID-19. "With increases in anxiety and loneliness, patients find comfort in peer support," said Chris Renfro-Wallace, the chief operating officer of PatientsLikeMe, a popular online community.
Sites like PatientsLikeMe and several others are giving rise to a patient-centered view of healthcare, challenging the idea that MD stands for medical deity. They're engaging people in new ways, such as virtual clinical trials. But with misinformation spreading online about health issues, including COVID-19, there's also reason for caution.
Engaged by Design
Following her diagnosis at age 50, Richardson searched the Web. "All I saw were infographics saying in five years I'd be dead."
Eventually, she found her Facebook groups and a site called Inspire, where she met others with her rare granulosa cell tumor. "You get 15 minutes with your doctor, but on social media you can keep posting until you satisfy your question."
Virtual communities may be especially helpful for people with rarely diagnosed diseases, who wouldn't otherwise meet. When Katherine Leon of Virginia suffered chest pain after the birth of her second son, doctors said it was spontaneous coronary artery dissection, or SCAD, involving a torn artery. But she had no risk factors for heart disease. Feeling like she was "wandering in the woods" with doctors who hadn't experienced her situation, she searched online and stumbled on communities like Inspire with members who had. The experience led her to start her own Alliance and the world's largest registry for advancing research on SCAD.
"Inspire is really an extension of yourself," she said. If designed well, online sites can foster what psychologist Keith Sawyer called group mind, a dynamic where participants balance their own voices with listening to others, maximizing community engagement in health. To achieve it, participants must have what Sawyer called a "blending of egos," which may be fostered when sites let users post anonymously. They must also share goals and open communication. The latter priority has driven Brian Loew, Inspire's CEO, to safeguard the privacy of health information exchanged on the site, often asking himself, "Would I be okay if a family member had this experience?"
The vibe isn't so familial on some of Facebook's health-focused groups. There, people might sense marketers and insurers peering over their shoulders. In 2018, a researcher discovered that companies could exploit personal information on a private Facebook community for BRCA-positive women. Members of the group started a nonprofit, the Light Collective, to help peer-to-peer support platforms improve their transparency.
PatientsLikeMe and Inspire nurture the shared experience by hosting pages on scores of diseases, allowing people to better understand treatment options for multiple conditions—and find others facing the same set of issues. Four in ten American adults have more than one chronic disease.
Sawyer observed that groups are further engaged when there's a baseline of common knowledge. To that end, some platforms take care in structuring dialogues among members to promote high-quality information, stepping in to moderate when necessary. On Inspire, members get emails when others reply to their posts, instead of instant messaging. The communication lag allows staff to notice misinformation and correct it. Facebook conversations occur in real-time among many more people; "moderation is almost impossible," said Leon.
Even on PatientsLikeMe and Inspire, deciding which content to police can be tough, as variations across individuals may result in conflicting but equally valid posts. Leon's left main artery was 90 percent blocked, requiring open heart surgery, whereas others with SCAD have angina, warranting a different approach. "It's a real range of experience," she explained. "That's probably the biggest challenge: supporting everyone where they are."
Critically, these sites don't treat illnesses. "If a member asks a medical question, we typically tell them to go to their doctor," said Loew, the Inspire CEO.
Increasingly, it may be the other way around.
The Patient Will See You Now
"Some doctors embrace the idea of an educated patient," said Loew. "The more information, the better." Others, he said, aren't thrilled about patients learning on their own.
"Doctors were behind the eight ball," said Shikha Jain, an oncologist in Chicago. "We were encouraged for years to avoid social media due to patient privacy issues. There's been a drastic shift in the last few years."
Jain recently co-founded IMPACT, a grassroots organization that networks with healthcare workers across Illinois for greater awareness of health issues. She thinks doctors must meet patients where they are—increasingly, online—and learn about the various platforms where patients connect. Doctors can then suggest credible online sources for their patients' conditions. Learning about different sites takes time, Jain said, "but that's the nature of being a physician in this day and age."
At stake is the efficiency of doctor-patient interactions. "I like when patients bring in research," Jain said. "It opens up the dialogue and lets them inform the decision-making process." Richardson, the cancer survivor, agreed. "We shouldn't make the physician the villain in this conversation." Interviewed over Zoom, she was engaging but quick to challenge the assumptions behind some questions; her toughness was palpable, molded by years of fighting disease—and the healthcare system. Many doctors are forced by that system into faster office visits, she said. "If patients help their doctor get to the heart of the issue in a shorter time, now we're going down a narrower road of tests."
These conversations could be enhanced by PatientsLikeMe's Doctor Visit Guide. It uses algorithms to consolidate health data that members track on the site into a short report they can share with their physicians. "It gives the doctor a richer data set to really see how a person has been doing," said Renfro-Wallace.
Doctors aren't the only ones benefiting from these sites.
Who Profits?
A few platforms like Inspire make money by connecting their members to drug companies, so they can participate in the companies' clinical trials to test out new therapies. A cynic might say the sites are just fronts for promoting the pharmaceuticals.
The need is real, though, as many clinical trials suffer from low participation, and the experimental treatments can improve health. The key for Loew, Inspire's CEO, is being transparent about his revenue model. "When you sign up, we assume you didn't read the fine print [in the terms of agreement]." So, when Inspire tells members about openings in trials, it's a reminder the site works with pharma.
"When I was first on Inspire, all of that was invisible to me," said Leon. "It didn't dawn on me for years." Richardson believes many don't notice pharma's involvement because they're preoccupied by their medical issues.
One way Inspire builds trust is by partnering with patient advocacy groups, which tend to be nonprofit and science-oriented, said Craig Lipset, the former head of clinical innovation for Pfizer. When he developed a rare lung disease, he joined the board of a foundation that partners with Inspire's platform. The section dedicated to his disease is emblazoned with his foundation's logo and colors. Contrast that with other sites that build communities at the direct behest of drug companies, he said.
Insurance companies are also eyeing these communities. Last month, PatientsLikeMe raised $26 million in financing from investors including Optum Ventures, which belongs to the same health care company that owns a leading health insurance company, UnitedHealthcare. PatientsLikeMe is an independent company, though, and data is shared with UnitedHealth only if patients provide consent. The site is using the influx of resources to gamify improvements in health, resembling programs run by UnitedHealth that assign nutrition and fitness "missions," with apps for tracking progress. Soon, PatientsLikeMe will roll out a smarter data tracking system that gives members actionable insights and prompts them to take actions based on their conditions, as well as competitions to motivate healthier behaviors.
Such as a race to vaccinate, perhaps.
Dealing with Misinformation
An advantage of health-focused communities is the intimacy of their gatherings, compared to behemoths like Facebook. Loew, Inspire's head, is mindful of Dunbar's rule: humans can manage only about 150 friends. Inspire's social network mapping suggests many connections among members, but of different strength; Loew hopes to keep his site's familial ambiance even while expanding membership. Renfro-Wallace is exploring video and voice-only meetings to enrich the shared experiences on PatientsLikeMe, while respecting members' privacy.
But a main driver of growth and engagement online is appealing to emotion rather than reason; witness Facebook during the pandemic. "We know that misinformation and scary things spread far more rapidly than something positive," said Ann Lewandowski, the executive director of Wisconsin Immunization Neighborhood, a coalition of health providers and associations countering vaccine hesitancy across the state.
"Facebook's moderation mechanism is terrible," she said. Vaccine advocates in her region who try to flag misinformation on Facebook often have their content removed because the site's algorithm associates their posts with the distortions they're trying to warn people about.
In the realm of health, where accessing facts can mean life or death—and where ad-based revenue models conflict with privacy needs—there's probably a ceiling on how large social media sites should scale. Loew views Inspire as co-existing, not competing with Facebook.
Propagandists had months to perfect campaigns to dissuade people from mRNA vaccines. But even Lewandowski's doctor was misinformed about vaccine side effects for her condition, multiple sclerosis. She sees potential for health-focused sites to convene more virtual forums, in which patient advocacy groups educate doctors and patients on vaccine safety.
Inspire is raising awareness about COVID vaccines through a member survey with an interactive data visualization. Sampling thousands of members, the survey found vaccines are tolerated well among patients with cancer, autoimmune issues, and other serious conditions. Analytics for online groups are evolving quickly, said Lipset. "Think about the acceleration in research when you take the emerging capability for aggregating health data and mash it up with patients engaged in sharing."
Lipset recently co-founded the Decentralized Trials and Research Alliance to accelerate clinical trials and make them more accessible to patients—even from home, without risking the virus. Sites like PatientsLikeMe share this commitment, collaborating with Duke's ALS Clinic to let patients join a trial from home with just two clinic visits. Synthetic control groups were created by PatientsLikeMe's algorithms, eliminating the need for a placebo arm, enabling faster results.
As for Richardson, the ovarian cancer patient, being online has given her another type of access—to experts. She was diagnosed this year with breast cancer. "This time is totally different," she said. On Twitter, she's been direct messaging cancer researchers, whose replies have informed her disease-management strategy. When her oncologists prescribed 33 radiation treatments, she counter-proposed upping the dosage over fewer treatments. Her doctors agreed, cutting unnecessary trips from home. "I'm immuno-compromised," she said. "It's like Russian roulette. You're crossing your finger you won't get the virus."
After years of sticking up for her own health, Richardson is now positioned to look out for others. She collaborated with the University of Illinois Cancer Center on a training module that lets patients take control of their health. She's sharing it online, in a virtual community near you. "It helps you make intelligent decisions," she said. "When you speak your physician's language, it shifts the power in the room."
Is Carbon Dioxide the New Black? Yes, If These Fabric-Designing Scientists Have Their Way
The entrepreneurs Tawfiq Nasr Allah (left, standing) and Benoit Illy (right, sitting down) at Fairbrics' lab in Clichy, France.
Each year the world releases around 33 billion tons of carbon dioxide into the atmosphere. What if we could use this waste carbon dioxide to make shirts, dresses and hats? It sounds unbelievable. But two innovators are trying to tackle climate change in this truly unique way.
Chemist Tawfiq Nasr Allah set up Fairbrics with material scientist Benoît Illy in 2019. They're using waste carbon dioxide from industrial fumes as a raw material to create polyester, identical to the everyday polyester we use now. They want to take a new and very different approach to make the fashion industry more sustainable.
The Dark Side of Fast Fashion
The fashion industry is responsible for around 4% of global emissions. In a 2015 report, the MIT Materials Systems Laboratory predicted that the global impact of polyester fabric will grow from around 880 billion kg of CO2 in 2015 to 1.5 trillion kg of CO2 by 2030.
Professor Greg Peters, an expert in environmental science and sustainability, highlights the wide-ranging difficulties caused by the production of polyester. "Because it is made from petrochemical crude oil there is no real limit on how much polyester can be produced...You have to consider the ecological damage (oil spills, fracking etc.) caused by the oil and gas industry."
Many big-name brands have pledged to become carbon neutral by 2050. But nothing has really changed in the way polyester is produced.
Some companies are recycling plastic bottles into polyester. The plastic is melted into ultra-fine strands and then spun to create polyester. However, only a limited number of bottles are available. New materials must be added because of the amount of plastic degradation that takes place. Ultimately, recycling accounts for only a small percentage of the total amount of polyester produced.
Nasr Allah and Illy hope they can offer the solution the fashion industry is looking for. They are not just reducing the carbon emissions that are conventionally produced by making polyester. Their process actually goes much further. It's carbon negative and works by using up emissions from other industries.
"In a sense we imitate what nature does so well: plants capture CO2 and turn it into natural fibers using sunlight, we capture CO2 and turn it into synthetic fibers using electricity."
Experts in the field see a lot of promise. Dr Phil de Luna is an expert in carbon valorization -- the process of converting carbon dioxide into high-value chemicals. He leads a $57-million research program developing the technology to decarbonize Canada.
"I think the approach is great," he says. "Being able to take CO2 and then convert it into polymers or polyester is an excellent way to think about utilizing waste emissions and replacing fossil fuel-based materials. That is overall a net negative as compared to making polyester from fossil fuels."
From Harmful Waste to Useful Raw Material
It all started with Nasr Allah's academic research, primarily at the French Alternative Energies and Atomic Energy Commission (CEA). He spent almost 5 years investigating CO2 valorization. In essence, this involves breaking the bonds between the carbon and oxygen atoms in CO2 to create bonds with other elements.
Recycling carbon dioxide in this way requires extremely high temperatures and pressures. Catalysts are needed to break the strong bonds between the atoms. However, these are toxic, volatile and quickly lose their effectiveness over time. So, directly converting carbon dioxide into the raw material for making polyester fibers is very difficult.
Nasr Allah developed a process involving multiple simpler stages. His innovative approach involves converting carbon dioxide to intermediate chemicals. These chemicals can then be transformed into the raw material which is used in the production of polyester. After many experiments, Nasr Allah developed new processes and new catalysts that worked more effectively.
"We use a catalyst to transform CO2 into the chemicals that are used for polyester manufacturing," Illy says. "In a sense we imitate what nature does so well: plants capture CO2 and turn it into natural fibers using sunlight, we capture CO2 and turn it into synthetic fibers using electricity."
The Challenges Ahead
Nasr Allah met material scientist Illy through Entrepreneur First, a programme which pairs individuals looking to form technical start-ups. Together they set up Fairbrics and worked on converting Nasr Allah's lab findings into commercial applications and industrial success.
"The main challenge we faced was to scale up the process," Illy reveals. "[It had to be] consistent and safe to be carried out by a trained technician, not a specialist PhD as was the case in the beginning."
They recruited a team of scientists to help them develop a more effective and robust manufacturing process. Together, the team gained a more detailed theoretical understanding about what was happening at each stage of the chemical reactions. Eventually, they were able to fine tune the process and produce consistent batches of polyester.
They're making significant progress. They've produced their first samples and signed their first commercial contract to make polyester, which will then be both fabricated into clothes and sold by partner companies.
Currently, one of the largest challenges is financial. "We need to raise a fair amount to buy the equipment we need to produce at a large scale," Illy explains.
How to Power the Process?
At the moment, their main scientific focus is getting the process working reliably so they can begin commercialization. In order to remain sustainable and economically viable once they start producing polyester on a large scale, they need to consider the amount of energy they use for carbon valorization and the emissions they produce.
The more they optimize the way their catalyst works, the easier it will be to transform the CO2. The whole process can then become more cost effective and energy efficient.
De Luna explains: "My concern is...whether their process will be economical at scale. The problem is the energy cost to take carbon dioxide and transform it into these other products and that's where the science and innovation has to happen. [Whether they can scale up economically] depends on the performance of their catalyst."
They don't just need to think about the amount of energy they use to produce polyester; they also have to consider where this energy comes from.
"They need access to cheap renewable energy," De Luna says, "...so they're not using or emitting CO2 to do the conversion." If the energy they use to transform CO2 into polyester actually ends up producing more CO2, this will end up cancelling out their positive environmental impact.
Based in France, they're well located to address this issue. France has a clean electricity system, with only about 10% of their electric power coming from fossil fuels due to their reliance on nuclear energy and renewables.
Where Do They Get the Carbon Dioxide?
As they scale up, they also need to be able to access a source of CO2. They intend to obtain this from the steel industry, the cement industry, and hydrogen production.
The technology to purify and capture waste carbon dioxide from these industries is available on a large scale. However, there are only around 20 commercial operations in the world. The high cost of carbon capture means that development continues to be slow. There are a growing number of startups capturing carbon dioxide straight from the air, but this is even more costly.
One major problem is that storing captured carbon dioxide is expensive. "There are somewhat limited options for permanently storing captured CO2, so innovations like this are important,'' says T. Reed Miller, a researcher at the Yale University Center for Industrial Ecology.
Illy says: "The challenge is now to decrease the cost [of carbon capture]. By using CO2 as a raw material, we can try to increase the number of industries that capture CO2. Our goal is to turn CO2 from a waste into a valuable product."
Beyond Fashion
For Nasr Allah and Illy, fashion is just the beginning. There are many markets they can potentially break into. Next, they hope to use the polyester they've created in the packaging industry. Today, a lot of polyester is consumed to make bottles and jars. Illy believes that eventually they can produce many different chemicals from CO2. These chemicals could then be used to make paints, adhesives, and even plastics.
The Fairbrics scientists are providing a vital alternative to fossil fuels and showcasing the real potential of carbon dioxide to become a worthy resource instead of a harmful polluter.
Illy believes they can make a real difference through innovation: "We can have a significant impact in reducing climate change."
