Davi Augusto Oliveira Pinto’s career in Brazil’s foreign service took him all over the world. His work as a diplomat for more than two decades exposed him to the realities of life for all kinds of people, which informed his interest in economics and public policy. 

Oliveira Pinto is now focused on strengthening his diplomatic work through his MIT education. He completed the MITx MicroMasters program in Data, Economics, and Design of Policy (DEDP), which is jointly administered by MIT Open Learning and the Abdul Latif Jameel Poverty Action Lab (J-PAL), and then applied and was accepted to the DEDP master’s program within MIT’s Department of Economics. 

“I think governments should be able to provide data-driven, research-supported services to their constituents,” he says. “Returning to my role as a diplomat, I hope to use the tools I acquired in the DEDP program to enhance my contributions as a public servant.”

Oliveira Pinto was one of Brazil’s representatives to the World Trade Organization (WTO), helped Brazilian citizens and companies abroad, and worked to improve relationships with governments in South Africa, Argentina, Italy, Spain, and Uruguay. He observed firsthand how economic disparities could influence laws and lives. He believes in a nonpartisan approach to public service, producing and sharing policy based on peer-reviewed data and research that can help as many people as possible. 

“We need public policy informed by evidence and science, rather than by politics and ideology,” he says. “My experience at MIT reinforced my conviction that diplomacy should be used to gather people from different backgrounds and develop joint solutions to our collective challenges.”

As someone responsible for dealing with international trade issues and who understands the potential negative, far-reaching impacts of poorly researched and instituted policies, Oliveira Pinto saw MIT and its world-class economics programs as potentially world-altering tools to help him advance his work. 

Advocacy and economics

Growing up in Minas Gerais, Brazil, Oliveira Pinto learned about the country’s past of economic cycles driven by exporting commodities like minerals and coffee. He also witnessed what he described as Brazil’s “eternal state of development,” one in which broad swaths of the population suffered, and very soon became aware of the impact that issues like inflation and unemployment had on the country. 

“I thought studying economics could help solve issues I observed when growing up,” he says.

Oliveira Pinto earned an undergraduate degree in economics from Universidade Federal de Minas Gerais and a master’s degree in public policy from Escola Nacional de Administração Pública.

Oliveira Pinto’s personal experiences and his commitment to understanding and improving the lives of his fellow Brazilians led him to enroll in the Instituto Rio Branco, Brazil’s diplomatic academy, where he was trained in a variety of disciplines. “I was drawn to investigate inequality between countries, which led to my diplomatic career,” he says. “I worked to help Brazilian migrants abroad, promoted Brazilian companies’ exports, represented Brazil at the WTO, and helped pandemic-era assistance efforts for people in Brazil’s poor border towns.”

During the pandemic, Oliveira Pinto found himself drawn to the DEDP MicroMasters program. He was able to review foundational economics concepts, improve his ability to synthesize and interpret data, and refine his analytical skills. “My favorite course, Data Analysis for Social Scientists, reinforced the critical importance of interpreting data correctly in a world where information is increasingly abundant,” he recalls. 

The online program also offered an opportunity for him to apply to study in person. Now at MIT, Oliveira Pinto is finishing his degree with a capstone project focused on how J-PAL works with governments to support the scaling of evidence-informed policies.  

J-PAL’s research center and network have built long-term partnerships with government agencies around the world to generate evidence from randomized evaluations and incorporate the findings into policy decisions. They work closely with policymakers to inform anti-poverty programs to improve their effectiveness, an area of particular interest to the Brazilian diplomat. 

“I’m trying to understand how J-PAL’s partnerships in these places are working, any lessons we can learn from successes, challenges faced, and how we can most effectively scale the successful programs,” he says.

Inside and beyond MIT

Oliveira Pinto was welcomed into a thriving, diverse community in Cambridge, a journey that was both edifying and challenging. “My family and I found a home,” he notes, observing that many Brazilians live in the area, “and it’s sobering to see so many people from my country working hard to build their lives in the U.S.”

Oliveira Pinto says working closely with members of the MIT community was one of the DEDP master’s program’s big draws. “The ability to forge connections with students and faculty while learning from Nobel laureates and accomplished researchers and practitioners is amazing,” he says. Collaborating with people from a variety of professional, experiential, and backgrounds, he notes, was especially satisfying. 

Oliveira Pinto offered special praise for MIT’s support for his family, describing it as “particularly rewarding.” “MIT offers so many different activities for families,” he says. “My wife and three daughters benefited from the support the Institute provides.” While taking advantage of his time in the States to visit Canada and Washington, D.C., they also made the most of their time in Cambridge. The family enjoyed sailing, swimming, yoga, sports, pottery, lectures, and more while Davi pursued his studies. “The facilities are awesome,” he continues.

Assessing and quantifying impact

Oliveira Pinto’s investigations have yielded some fascinating findings. “Data can be misused,” he notes. “I learned how easily data can tell all kinds of stories, so it’s important to be careful and rigorous when assessing different claims.” He recalls how, during an econometrics class, he learned about parties on opposite sides of a health insurance divide pursuing radically different ends using the same data, each side promoting different views. 

Oliveira Pinto believes his studies have improved his abilities as a diplomat, one of the reasons he’s excited about his eventual return to the public service. “I’ll return to government service armed with the skills the DEDP program and the research conducted during my capstone project have provided,” he says. “My job as a diplomat is to seek opportunities to connect with different people, investigate carefully, and find common ground,” work for which his DEDP MicroMasters and master’s studies have helped prepare him.

Completing his capstone, Oliveira Pinto hopes to draw lessons from J-PAL’s work with governments to improve constituents' quality of life. He’s helping generate case studies that may foster future collaborations between researchers and the public sector. 

“Work like this can be a good opportunity for governments interested in a research-supported, data-driven approach to policymaking,” he says. 

There are 63 million people caring for family members with an illness or disability in the U.S. That translates to one in four adults devoting their time to helping loved ones with things like transportation, meals, prescriptions, and medical appointments.

Caregiving exacts a huge toll on the people responsible, and ianacare is seeking to lessen the burden. The company, founded by Steven Lee ’97, MEng ’98 and Jessica Kim, has built a platform that helps caregivers navigate available tools and local resources, build a network of friends and family to assist with everyday tasks, and coordinate meals, rides, and care shifts.

The name ianacare is short for “I am not alone care.” The company’s mission is to equip and empower the millions of people who perform a difficult and underappreciated role in our society.

“Family caregivers are the invisible backbone of the health care system,” Lee says. “Without them, the health care system would literally collapse, but they are still largely unrecognized. Ianacare acts as the front door for family caregivers. These caregivers are often thrust into this role untrained and unguided. But the moment they start, they have to become experts. Ianacare fills that gap.”

The company has partnered with employers and health care providers to serve more than 50,000 caregivers to date. And thanks to a partnerships with organizations like Elevance Health, the American Association of Retired Persons (AARP), and Medicare providers, its coordination and support tools are available to family caregivers across the country.

“Ultimately we want to make the biggest impact possible,” Lee says. “From a business standpoint, the 50,000 caregivers we’ve served is a huge number. But from the overall universe of caregivers that could use our help, it’s relatively small. We’re on a mission to help all 63 million caregivers.”

From ad tech to ianacare

As an electrical engineering and computer science student at MIT in the 1990s, Lee conducted research on early speech-recognition technology as part of the Spoken Language Systems group in MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL).

Following graduation, Lee started a company with Waikit Lau ’97 that optimized video advertising placement within streams. The company has gone through several mergers and acquisitions, but is now part of the public company Magnite, which places the ads on platforms like Netflix, Hulu, and Disney+.

Lee left the company in 2016 and began advising startups through programs including MIT’s Venture Mentoring Service as he looked to work on something he would find more meaningful.

“Over the years, the MIT network has been invaluable for connecting with customers, recruiting top talent, and engaging investors,” Lee says. “So much innovation flows out of MIT, and I’ve loved giving back, especially working alongside [VMS Venture Mentor] Paul Bosco ’95 and the rest of the VMS team. It’s deeply rewarding to share the best practices I’ve learned with the next generation of innovators.”

In 2017, Lee met Kim, who was caregiving for her mother with pancreatic cancer. Hearing about her experience brought him back to his own family’s challenges caring for his grandfather with Parkinson’s disease when Lee was a child.

“We realized the gaps that existed in caregiving support three decades ago still exist,” Lee says. “Nothing has changed.”

Officially launched in 2018, ianacare may seem far-removed from speech recognition or ad technologies, but Lee sees the work as an extension of his previous experiences.

“In my mind, AI got its start in speech recognition, and the intelligence we use to surface recommendations and create care plans for family caregivers uses a lot of the same statistical modeling techniques I used in speech recognition and ad placement,” Lee says. “It all goes back to the foundation I got at MIT.”

The founders first launched a free solution that allowed caregivers to connect with friends and family members to coordinate caregiving tasks.

“In our app, you can coordinate with anyone who’s interested in helping,” Lee says. “When you share a struggle with a friend or co-worker, they always say, ‘How can I help?’ But caregivers rarely go back to them and actually ask. In our platform, you can add those people to your informal care team and ask the team for help with something instead of having to text someone directly, which you’re less likely to do.”

Next, the founders built an enterprise solution so businesses could help employee caregivers, adding features like resource directories and ways to find and select various caregiving tools.

“An immense amount of local resources are available, but nobody knows about them,” Lee says. “For instance, every county in the country has an Area Agency on Aging, but these agencies aren’t marketing experts, and caregivers don’t know where to get guidance.”

Last year, ianacare began working with AARP and health care providers participating in the nationwide GUIDE model (for “Guiding an Improved Dementia Experience”) to improve the quality of life for dementia patients and their caregivers. Through the voluntary program, participants can use ianacare’s platform to coordinate care, access educational resources, and access free respite care up to $2,500 each year.

Lee says the CMS partnership gives ianacare a pathway to reach millions of people caring for dementia patients across the country.

“This is already a crisis, and it will get worse because we have an aging population and a capacity-constraint in our health care system,” Lee says. “The population above 65 is set to double between 2000 and 2040. We aren’t going to have three times the hospitals or three times the doctors or nurse practitioners. So, we can either make clinicians more efficient or move more health care into the home. That’s why we have empower family caregivers.”

Aging with dignity

Lee recalls one family who used ianacare after their son was born with a severe disease. The child only lived eight months, but for those eight months, the parents had meals delivered to them in the hospital by friends and family.

“It was not something they had to worry about the entire time their son was alive,” Lee says. “It’s been rewarding to help these people in so much need.”

Other ianacare users say the platform has helped them keep their parents out of the hospital and lessen their depression and anxiety around caregiving.

“Nobody wants to die in a hospital, so we’ve worked hard to honor the wishes of loved ones who want to age in the home,” Lee says. “We have a lot of examples of folks who, if our support was not there, their loved one would have had to enter a nursing home or institution. Ianacare is there to ensure the home is safe and that the caregiver can manage the care burden. It’s a win-win for everybody because it’s also less costly for the health care system.”

Age verification has officially arrived in the UK thanks to the Online Safety Act (OSA), a UK law requiring online platforms to check that all UK-based users are at least eighteen years old before allowing them to access broad categories of “harmful” content that go far beyond graphic sexual content. EFF has extensively criticized the OSA for eroding privacy, chilling speech, and undermining the safety of the children it aims to protect. Now that it’s gone into effect, these countless problems have begun to reveal themselves, and the absurd, disastrous outcome illustrates why we must work to avoid this age-verified future at all costs.

Perhaps you’ve seen the memes as large platforms like Spotify and YouTube attempt to comply with the OSA, while smaller sites—like forums focused on parenting, green living, and gaming on Linux—either shut down or cease some operations rather than face massive fines for not following the law’s vague, expensive, and complicated rules and risk assessments. 

But even Reddit, a site that prizes anonymity and has regularly demonstrated its commitment to digital rights, was doomed to fail in its attempt to comply with the OSA. Though Reddit is not alone in bowing to the UK mandates, it provides a perfect case study and a particularly instructive glimpse of what the age-verified future would look like if we don’t take steps to stop it.

It’s Not Just Porn—LGBTQ+, Public Health, and Politics Forums All Behind Age Gates

On July 25, users in the UK were shocked and rightfully revolted to discover that their favorite Reddit communities were now locked behind age verification walls. Under the new policies, UK Redditors were asked to submit a photo of their government ID and/or a live selfie to Persona, the for-profit vendor that Reddit contracts with to provide age verification services. 

For many, this was the first time they realized what the OSA would actually mean in practice—and the outrage was immediate. As soon as the policy took effect, reports emerged from users that subreddits dedicated to LGBTQ+ identity and support, global journalism and conflict reporting, and even public health-related forums like r/periods, r/stopsmoking, and r/sexualassault were walled off to unverified users. A few more absurd examples of the communities that were blocked off, according to users, include: r/poker, r/vexillology (the study of flags), r/worldwar2, r/earwax, r/popping (the home of grossly satisfying pimple-popping content), and r/rickroll (yup). This is, again, exactly what digital rights advocates warned about. 

Every user in the country is now faced with a choice: submit their most sensitive data for privacy-invasive analysis, or stay off of Reddit entirely. Which would you choose? 

The OSA defines "harmful" in multiple ways that go far beyond pornography, so the obstacles the UK users are experiencing are exactly what the law intended. Like other online age restrictions, the OSA obstructs way more than kids’ access to clearly adult sites. When fines are at stake, platforms will always default to overcensoring. So every user in the country is now faced with a choice: submit their most sensitive data for privacy-invasive analysis, or stay off of Reddit entirely. Which would you choose? 

Again, the fact that the OSA has forced Reddit, the “heart of the internet,” to overcensor user-generated content is noteworthy. Reddit has historically succeeded where many others have failed in safeguarding digital rights—particularly the free speech and privacy of its users. It may not be perfect, but Reddit has worked harder than many large platforms to defend Section 230, a key law in the US protecting free speech online. It was one of the first platforms to endorse the Santa Clara Principles, and it was the only platform to receive every star in EFF’s 2019 “Who Has Your Back” (Censorship Edition) report due to its unique approach to moderation, its commitment to notice and appeals of moderation decisions, and its transparency regarding government takedown requests. Reddit’s users are particularly active in the digital rights world: in 2012, they helped EFF and other advocates defeat SOPA/PIPA, a dangerous censorship law. Redditors were key in forcing members of Congress to take a stand against the bill, and were the first to declare a “blackout day,” a historic moment of online advocacy in which over a hundred thousand websites went dark to protest the bill. And Reddit is the only major social media platform where EFF doesn’t regularly share our work—because its users generally do so on their own. 

If a platform with a history of fighting for digital rights is forced to overcensor, how will the rest of the internet look if age verification spreads? Reddit’s attempts to comply with the OSA show the urgency of fighting these mandates on every front. 

We cannot accept these widespread censorship regimes as our new norm. 

Rollout Chaos: The Tech Doesn’t Even Work! 

In the days after the OSA became effective, backlash to the new age verification measures spread across the internet like wildfire as UK users made their hatred of these new policies clear. VPN usage in the UK soared, over 500,000 people signed a petition to repeal the OSA, and some shrewd users even discovered that video game face filters and meme images could fool Persona’s verification software. But these loopholes aren’t likely to last long, as we can expect the age-checking technology to continuously adapt to new evasion tactics. As good as they may be, VPNs cannot save us from the harms of age verification. 

In effect, the OSA and other age verification mandates like it will increase the risk of harm, not reduce it. 

Even when the workarounds inevitably cease to function and the age-checking procedures calcify, age verification measures still will not achieve their singular goal of protecting kids from so-called “harmful” online content. Teenagers will, uh, find a way to access the content they want. Instead of going to a vetted site like Pornhub for explicit material, curious young people (and anyone else who does not or cannot submit to age checks) will be pushed to the sketchier corners of the internet—where there is less moderation, more safety risk, and no regulation to prevent things like CSAM or non-consensual sexual content. In effect, the OSA and other age verification mandates like it will increase the risk of harm, not reduce it. 

If that weren’t enough, the slew of practical issues that have accompanied Reddit’s rollout also reveals the inadequacy of age verification technology to meet our current moment. For example, users reported various bugs in the age-checking process, like being locked out or asked repeatedly for ID despite complying. UK-based subreddit moderators also reported facing difficulties either viewing NSFW post submissions or vetting users’ post history, even when the particular submission or subreddit in question was entirely SFW. 

Taking all of this together, it is excessively clear that age-gating the internet is not the solution to kids’ online safety. Whether due to issues with the discriminatory and error-prone technology, or simply because they lack either a government ID or personal device of their own, millions of UK internet users will be completely locked out of important social, political, and creative communities. If we allow age verification, we welcome new levels of censorship and surveillance with it—while further lining the pockets of big tech and the slew of for-profit age verification vendors that have popped up to fill this market void.

Americans, Take Heed: It Will Happen Here Too

The UK age verification rollout, chaotic as it is, is a proving ground for platforms that are looking ahead to implementing these measures on a global scale. In the US, there’s never been a better time to get educated and get loud about the dangers of this legislation. EFF has sounded this alarm before, but Reddit’s attempts to comply with the OSA show its urgency: age verification mandates are censorship regimes, and in the US, porn is just the tip of the iceberg. 

US legislators have been disarmingly explicit about their intentions to use restrictions on sexually explicit content as a Trojan horse that will eventually help them censor all sorts of other perfectly legal (and largely uncontroversial) content. We’ve already seen them move the goalposts from porn to transgender and other LGBTQ+ content. What’s next? Sexual education materials, reproductive rights information, DEI or “critical race theory” resources—the list goes on. Under KOSA, which last session passed the Senate with an enormous majority but did not make it to the House, we would likely see similar results here that we see in the UK under the OSA.

Nearly half of U.S. states have some sort of online age restrictions in place already, and the Supreme Court recently paved the way for even more age blocks on online sexual content. But Americans—including those under 18—still have a First Amendment right to view content that is not sexually explicit, and EFF will continue to push back against any legislation that expands the age mandates beyond porn, in statehouses, in courts, and in the streets. 

What can you do?

Call or email your representatives to oppose KOSA and any other federal age-checking mandate. Tell your state lawmakers, wherever you are, to oppose age verification laws. Make your voice heard online, and talk to your friends and family. Tell them about what’s happening to the internet in the UK, and make sure they understand what we all stand to lose—online privacy, security, anonymity, and expression—if the age-gated internet becomes a global reality. EFF is building a coalition to stop this enormous violation of digital rights. Join us today.
