Turning Rejection Into a Roadmap: Advice for the Next Generation of Mental Health Leaders

A Conversation with Tom Osborn, Founder of Africa’s Largest Mental Health Provider Shamiri Institute

Aaliyah Nadirah Madyun, program director at the Stavros Niarchos Foundation (SNF) Global Center for Child and Adolescent Mental Health at the Child Mind Institute, recently sat down with Tom Osborn, founder of the Shamiri Institute and an International Advisory Board member at the SNF Global Center. They discussed Osborn’s remarkable journey as a young entrepreneur.

At just 18, while studying at Harvard University, Osborn founded the Shamiri Institute, which has since grown into Africa’s largest youth mental health provider — now reaching over 100,000 young people annually and having trained and employed more than 3,000 providers. In this candid conversation, Osborn shares hard-won lessons on resilience, mentorship, and well-being. He offers advice to the SNF Global Center’s Youth Council members — many of whom are launching their own mental health initiatives in communities across Greece, Brazil, South Africa, and beyond.

AM: You founded Shamiri when you were just 18. Many members of our SNF Global Center Youth Councils are now launching their own mental health organizations. What advice would you give them?

TO: I think these past three to five years post-COVID have been quite good for mental health. There’s just more dialogue, more conversation. It’s maybe one of the best times to start working in mental health. There is a big space for young people to be leaders. On the other hand, it’s also very difficult.

AM: What kind of difficulties can young people expect to encounter?

TO: It’s very difficult for a few reasons. We normally start this work because we have a lot of passion, enthusiasm, and commitment to the cause. But that is not the day-to-day of being a social entrepreneur. It’s convincing people to partner with you, to fund you, etc., which is a completely different skill set to learn. And the second part is getting a level of comfort with failure. Because the reality is, on average, nine out of ten doors that you try to open will not open; especially when you are starting. For example, if you’re in Brazil and there are 100 other young people trying to start something, there is a finite pool of opportunities and resources. So, when you are starting, part of the initial process requires you to develop resilience and a growth mindset.

AM: Could you speak about the role mentorship has played in your journey, and how young entrepreneurs can leverage mentorship to navigate the challenges of building something from the ground up?

TO: Mentorship is really crucial. Finding folks — researchers, practitioners, or just folks in the community — who can help provide guidance as you build the skills you need to be an effective entrepreneur.

AM: How would you recommend young people go about finding a mentor? It seems like that ability, identifying and cultivating a mentoring relationship, might be a skill set in itself.

TO: In my experience, there are three pathways. In many countries we have what we call accelerators, which look for young people who literally have an idea and enthusiasm, and then take them through 10–16 weeks of bootcamp where they can learn the skills to develop their idea. So, that’s one pathway. The second pathway, which really worked for me but may sound intimidating, is direct outreach to folks who have done something similar. So, you can do some research. It doesn’t have to even be related to mental health. It can be education or some broader thing. But find someone who has built something that you admire. You will be surprised how many people are willing to support and pay it forward, because we all have benefited from the help of someone else. I created an Excel spreadsheet with a list of people who I looked up to, and I reached out to them on LinkedIn. Sometimes you can even find their email. Some people said “no”, but if you reach out to 10 or 20 people, some people will talk to you. And the third pathway is . . . increasingly we have a lot of resources like the SNF Global Center Youth Councils and international organizations that deal with mental health. You can join these organizations to expand your network.

AM: Could you share your story with us and tell us how you got started?

TO: I started when I was in University as part of a research project I was doing when I was studying psychology. I needed to do something for my thesis and in the process of doing that I applied to an accelerator. I also went to my professor and asked him, ‘Do you know anyone who could connect me with?’ In fact, he helped me write my first grant and gave me the opportunity to learn those entrepreneurial skills.

AM: Starting at such a young age, one can imagine that you must have encountered many challenges and setbacks. What were the key lessons you took away from that growth period?

TO: The reality of this work, and not to discourage people but to give a factual picture, is that there are more setbacks than there are wins. Part of the process is that you learn from the setbacks. I can give you an example of some of my own setbacks. In my first year of doing this, we tried to raise money. We applied for grants, sent out proposals, etc.; but we couldn’t raise any money. So, what I did after getting the rejection is I would email and ask, “Do you have any feedback for us about why we didn’t get the funding?” or “Can we jump on a call so you can explain what we can do better?” What I learned from that was the way I was communicating what we were doing made sense in my mind, but I wasn’t putting myself in the shoes of the person who was reviewing the proposal. I only have five to ten minutes of someone’s time. So, how can I really simplify my message? For example, my first proposal was, “Shamiri does task-shifting mental health interventions for adolescent depression, anxiety, etc.” If you are in the field, you maybe get it. But if you are somebody who is just reading grants on mental health education, you don’t really get it. Now we say, “Shamiri means thrive and we enable young people to thrive.” So that invites people to ask how we’re helping people to thrive.

AM: What is another setback that surprised you?

A second example of a failure is getting buy-in from the beneficiaries that we were trying to work with. I thought, “We have this great idea, we’ve done this research, and it works. We’re going to go to schools and they’re going to be like, ‘This is great! Come work with us.’ Teachers are going to want to work with us.” But actually, in our first three years we were trying to work with 25,000 students and we ended up working with only 1,000 students. We really struggled with getting people to sign up. The lesson from that was we were thinking more from the idea this was our product, rather than thinking, “What is the problem that I am trying to solve for this person?” To give a concrete example, there are three people we need to get buy-in from: young people in schools, teachers, and parents. Just having a great product does not mean that people are going to use it. You need to figure out what the problem is. How can I solve it? How do I communicate this to users?

AM: I can imagine that dealing with failures and setbacks is extremely hard, especially for a young person. What would you say to a young person who is currently experiencing this?

TO: Finding ways to stay grounded and healthy from a well-being perspective is really crucial. Identify what matters to you and connect with those things. And ideally if you can find a way to build a routine around that, it could help. Doing this work takes a big toll. If you don’t find ways to ground yourself and get the energy to continue with this, you may burn out.

AM: Do you have some final words for our Youth Council members and other young people reading this?

TO: Those closest to the problem are those closest to the solution. I am from Kenya, which is a really young country. The median age is 19 and 70 percent of the population is under 30. If we are to solve some of these pressing problems, including mental health, those solutions are going to have to come from young people.

Google DeepMind is worried about what happens when millions of agents start to interact

Google DeepMind is funding research into the potential dangers of situations where millions of different AI agents interact with each other online.

According to Rohin Shah, who directs the company’s AGI safety and alignment research, the mass-market arrival of agents that can carry out tasks without human oversight and follow instructions given to them by other agents creates a whole new class of risk.

In an effort to address this, Google DeepMind—which made agent-based tools a centerpiece of Google I/O last month—has teamed up with several other organizations to announce a $10 million funding pot for researchers to study the behavior of multi-agent systems and come up with ways to prevent unsafe scenarios. Joining Google DeepMind are Schmidt Sciences, a philanthropic foundation set up by Eric and Wendy Schmidt; ARIA, the UK government’s moonshot agency; the Cooperative AI foundation, a UK-based nonprofit research outfit; and Google’s charitable arm, Google.org.

I asked Shah and James Fox, who leads the Science of Trustworthy AI program at Schmidt Sciences, what they hope to achieve with that $10 million. It’s no small sum, but it’s dwarfed by the budgets commanded by Google DeepMind’s own research teams.

The aim is to kick-start research outside tech companies, says Shah: “The strength of academia is that it can look really quite far into the future and do the kind of work that isn’t top of mind at industry labs.”

“The main issue is that there just isn’t really a field of research for multi-agent safety yet,” he adds. “And we would like there to be.”

The concern is that as more and more AI agents get deployed and begin working together, we could hit a tipping point where imagined scenarios become real. “We see this with humanity, too,” says Shah. “Our institutions can accomplish things that no individual human can.”

Shah thinks that we have a few more months to go before agents are deployed throughout the economy in numbers that make potential risks a real concern. He wants to get ahead of that moment.

Risky business

What risks are we talking about, exactly? The possibilities that Shah and Fox have in mind mostly boil down to supercharged versions of bad things that happen on the internet already: scams, prompt injections (where an AI agent is fed malicious instructions, turning it into a self-guiding piece of malware), other forms of cyberattack. We look at what humans do now and ask what the agent version of that would be, says Shah.  

“We’ve got this digital commons that is integral to how society works, and you really want to ensure that this doesn’t descend into just absolute anarchy,” says Fox.

(I asked Shah if they were considering any worst-case scenarios more on the doomer end of the spectrum, such as widespread economic collapse. “Certainly not if we’re talking by the end of the year,” he said. That’s only six months away! He laughed. “Okay, a while after that.”)

Shah and Fox both think that the only way to understand what might happen when large numbers of multi-agent systems interact with each other is to run realistic simulations. They want researchers to drop AI agents into sandboxes and study what they do.

You can’t predict what’s going to happen by studying single agents, or even small groups of agents, in isolation. You can’t assume that AI agents underpinned by LLMs will always act rationally, says Fox. And the complexity comes from having huge numbers of interactions at once.

Some researchers, including a team at Google DeepMind, have argued that artificial general intelligence (if possible at all) could come not from a single super-smart model but from a kind of agent hive mind, where the capabilities of the whole add up to more than the sum of its parts.  

Lack of trust

Google DeepMind is not the only top AI firm warning about the risks of the technology it is building. A couple of weeks ago, Anthropic published guidelines for deploying AI agents based on an approach to cybersecurity known as zero trust, which starts with the assumption that a computer system is vulnerable, an agent is an attacker, and a breach will happen.

Refael Angel, cofounder and CTO of Akeyless, a cybersecurity firm based in Tel Aviv, agrees that understanding the new risks introduced by agent-based systems is crucial.  

Every approach to security in the past has assumed that the machine in question was software written by a human, doing fixed things on fixed paths, says Angel: “An agent breaks all of those assumptions. It reasons, it improvises, and it can be hijacked by a single sentence buried in a document it was asked to read.”

Angel welcomes this new funding. “No single lab should author the safety standards everyone else has to trust,” he says. But he cautions that safety researchers can overlook boring problems that are already here in favor of more exotic hypothetical ones.

And yet, Fox notes, risks that were hypothetical a few years ago are now very real: “The future’s come more quickly than perhaps expected.”

The Intersectionality of OCD and the Shame Surrounding Sexuality 

By Mike Vatter

Obsessive-Compulsive Disorder (OCD) is often misunderstood as a condition involving excessive cleanliness, organization, or ritualistic behavior. In reality, OCD is a complex mental health disorder characterized by intrusive thoughts, unwanted images, fears, and compulsive behaviors intended to reduce anxiety. One of the least understood and most painful aspects of OCD occurs when intrusive thoughts intersect with sexuality, creating a profound sense of shame, confusion, and isolation. 

Sexuality is already a deeply personal aspect of human identity. Many people grow up receiving messages, whether from family, religion, culture, or society, that certain thoughts, desires, or identities are inappropriate or unacceptable. When OCD enters this landscape, it can weaponize these fears and vulnerabilities. Intrusive thoughts often target what a person values most or fears most. As a result, individuals with OCD may experience unwanted sexual thoughts that feel completely inconsistent with their values, identity, or desires.

Someone with OCD may become trapped in relentless questioning: “What if I am attracted to someone I shouldn’t be attracted to?” “What if these thoughts mean something about who I really am?” “What if I am secretly a bad person?” These questions are not driven by genuine desire but by overwhelming anxiety and uncertainty. Nevertheless, the individual often feels compelled to seek reassurance, analyze their reactions, or avoid situations that trigger distress. 

The shame surrounding sexuality intensifies this struggle. Society frequently treats sexual thoughts as reflections of character rather than recognizing that thoughts can occur without intent, desire, or meaning. For people with OCD, this misunderstanding can be devastating. Many become terrified that simply having an intrusive thought makes them immoral, dangerous, or fundamentally flawed. As a result, they often suffer in silence, afraid that disclosing their thoughts will lead to judgment or rejection. 

The intersection of OCD and sexuality can affect people of all sexual orientations and gender identities. Some individuals experience obsessions centered on questioning their sexual orientation, regardless of whether they identify as heterosexual, gay, bisexual, or otherwise. Others experience intrusive thoughts involving taboo or unwanted sexual scenarios. In each case, the distress comes not from the thoughts themselves but from the meaning the individual fears those thoughts represent. 

This experience is particularly challenging because shame thrives in secrecy. The more a person attempts to suppress, analyze, or eliminate intrusive thoughts, the stronger and more persistent those thoughts often become. OCD feeds on certainty-seeking, convincing individuals that if they can just think hard enough or find enough reassurance, they will finally feel safe. Unfortunately, the cycle rarely ends that way. 

Recovery begins when individuals learn to separate intrusive thoughts from identity and intention. Evidence-based treatments such as Exposure and Response Prevention (ERP) help people tolerate uncertainty and reduce compulsive responses. Through treatment, many discover that thoughts are not actions, urges are not intentions, and anxiety is not evidence. They learn that having an intrusive thought says far less about their character than the courage it takes to face that thought without engaging in compulsions. 

Understanding the intersectionality of OCD and sexual shame requires compassion, education, and nuance. It demands that we challenge cultural assumptions about thoughts and morality while recognizing the unique suffering OCD can create. When people understand that intrusive thoughts are a symptom of a disorder rather than a reflection of character, shame begins to lose its power. 

Ultimately, healing occurs not when every intrusive thought disappears, but when individuals no longer measure their worth by the thoughts that enter their minds. By replacing shame with understanding and fear with self-compassion, people living with OCD can reclaim both their mental health and their sense of identity.

The Download: whole-body rejuvenation drugs and five things to know about AI

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.

David Sinclair plans to test whole-body rejuvenation drugs in the XPrize competition

The outspoken longevity scientist David Sinclair has predicted that, one day, you’ll go to the doctor and get a prescription that will make you 10 years younger. MIT Technology Review has learned of his latest step toward this: human tests of a “reprogramming” drug.

Sinclair, a biologist at Harvard Medical School, plans to launch the tests in a $101 million competition organized by the XPrize Foundation. The winners will “restore” a person to an earlier apparent age, as measured by improvements in immune, cognitive, and muscle function.

The grand prize goes to any team able to show a 10-year (or greater) relative improvement after one year of treatment. 

Sinclair says he plans to give an oral drug mixture to volunteers, in a bid to seek “evidence for age restoration in humans.” Find out how he hopes to reverse ageing through chemical reprogramming.

Five things you need to know about AI

—Will Douglas Heaven

At SXSW London last week, I gave a talk called “Five things you need to know about AI,” in which I shared what I think are the biggest themes in AI right now.

I pulled a few things from our first AI10 list, an annual guide to the top trends in this buzzy world, but I also veered off on several tangents. In my half-hour slot, I tried to cover the key talking points that I think help to make sense of what’s going on in tech—and thus the economy—today.

Inside the race to make human sex cells in the lab

An embryo forms when sperm meets egg. But what if we could start with other cells—if a blood sample or skin biopsy could be transformed into “artificial” sperm and eggs? What if those were all you needed to make a baby?

That’s the promise of a radical approach to reproduction. Scientists have already created artificial eggs and sperm from mouse cells and used them to create mouse pups. Artificial human sex cells are next.

The advances could herald the end of infertility, but they raise major scientific and ethical challenges.

David Sinclair plans to test whole-body rejuvenation drugs in the XPrize competition

The outspoken longevity scientist David Sinclair has been predicting that one day, you’ll go to the doctor and get a prescription that will make you 10 years younger.

Now MIT Technology Review has learned that he has plans to launch human tests of an oral “reprogramming” drug as part of a $101 million competition organized by the XPrize Foundation. 

The foundation is offering cash awards to teams able to “restore” a person to an earlier apparent age, as measured by improvements in immune, cognitive, and muscle function. 

The grand prize goes to any team able to show a 10-year (or greater) relative improvement after one year of treatment. 

Reached by phone, Sinclair, a biologist at Harvard Medical School, confirmed that he plans to give an oral drug mixture to volunteers in a bid to seek “evidence for age restoration in humans.”

The trial, if it goes forward, will be a significant new development in the race to harness so-called epigenetic reprogramming. That technology is based on the discovery, 20 years ago, of powerful genes able to turn an adult cell into a stem cell similar to those found in embryos.

The age-reversal effect is believed to occur via a resetting of molecular controls on DNA known as epigenetic marks, which help determine a cell’s overall metabolism and identity.

Companies are now racing to use that phenomenon for a new form of rejuvenation medicine. Only this January, one of Sinclair’s companies, Life Biosciences, made news by winning approval to launch an initial human trial using a set of powerful reprogramming genes. The company announced today it had treated its first patient. 

But that test involves a complex gene therapy and is limited to patients’ eyes, where it could treat conditions like glaucoma. 

Sinclair’s new plan is bolder: a reprogramming drug you’d swallow in order to promote such effects across the body. 

“What we’re aiming to do is to epigenetically restore the animal and eventually the person,” he says. “It is true that we’ve been doing extensive animal studies with the oral agent and are looking to compete in the XPrize.”

This alternative method, chemical reprogramming, uses drugs to mimic the effects of the embryonic genes. That is significant because drug compounds can travel through the bloodstream, reaching most or all cells in a person’s body. 

Some experts expressed caution, saying the chemical process, at least as used in labs, is extremely harsh and not even particularly effective. “Who doesn’t dream of whole-body rejuvenation? I think it’s a great goal,” says Sergiy Velychko, founder of Soxogen, a stealth reprogramming company in Boston. “But these chemicals are used in very, very high concentrations for cell reprogramming.”

Sinclair declined to describe the exact makeup of the drug candidate, code-named SL-100, calling its contents “highly, highly confidential.”

However, he has previously published lab studies of what he called “epigenetic age-reversal cocktails,” which mixed powerful chemicals with known supplements and commercially available medicines. 

It’s those latter components that would be easiest to test on people, since doctors are free to prescribe them, even for unusual objectives like age reversal. James Clement, head of Betterhumans, an organization that specializes in life-extension studies using existing drugs, said in a message that he is “running clinical trials” of an oral reprogramming cocktail for Sinclair’s XPrize team.

Sinclair’s team is competing in the XPrize Healthspan Competition, launched in 2023. It follows several previous competitions that focused on commercial spaceflight, lunar landings, and other goals. The XPrize Foundation is led by executive chairman Peter Diamandis, also an active promoter of longevity research.

“If two teams are equivalent, they would split the award,” says Jamie Justice, a doctor and executive director for the contest, which was bankrolled by Saudi Arabia’s Hevolution Foundation, “But it will be incredibly hard to even get to one winner.”

Justice says a judging panel is now in the process of picking 10 finalists from 65 teams that have been exploring health foods, lifestyle interventions, digital trackers, and drug compounds. 

Sinclair’s team, Justice says, was a late entrant to the contest, but like all teams, it would be required to move into wider human tests starting this year. “You have to be ready and in trials,” she says.

The race to harness the reprogramming phenomenon and apply it to living people is heating up, even outside the XPrize competition. On June 2, a startup called NewLimit, founded by the crypto billionaire Brian Armstrong, said it had raised a further $435 million, from investors including Peter Thiel’s Founders Fund, to support what it calls “age reprogramming.” 

The company says it is working toward delivering genetic reprogramming instructions to the liver, to treat diseases of that organ.

But Sinclair has been saying that whole-body rejuvenation is a possibility too. And for that, chemicals, rather than gene therapy, could be the most practical strategy. 

Sinclair says his lab has been searching for such compounds and is starting to use AI “to improve the oral agents that we’re testing.”

Chemical reprogramming cocktails, as used in labs, typically involve a mix of vitamins, approved drugs, and experimental molecules. For instance, one recipe Sinclair filed a patent on includes the supplement forskolin,  the antidepressant tranylcypromine, and an experimental chemical, laduviglusib, which has been tested against Alzheimer’s, among other ingredients.

“In those days it was a six-factor cocktail,” Sinclair says of his earlier research. “But we’ve come a long way. I can’t disclose what’s in it, but it’s an improvement and an advance on that, and we’ve done a number of animal studies. They are not published, but we’ve been doing them for a long time, and we want to make sure that we’ve done a full investigation of safety and efficacy before we release any of the data.”

While Sinclair’s results aren’t published, other teams say attempts to reverse the age of entire animals using chemical drugs haven’t worked yet. Last year, the lab of Vadim Gladyshev, another Harvard biologist and a member of a different XPrize team, reported on its attempt to rejuvenate mice by installing pumps in their bodies that released controlled doses of seven compounds.

Gladyshev says the procedure proved to be toxic. “The idea was to see if we could rejuvenate whole animals. Unfortunately, we have not found [the right] conditions,” he says. “At low concentrations there was no effect, and high concentrations were toxic.”

Gladyshev says he doesn’t know what is in Sinclair’s cocktail, but says that “trying to improve the combinations makes sense.”

Sinclair, who is the author of several books on aging and has a large social media following, has frequently been criticized by other scientists for making unproven rejuvenation claims. 

In 2024, he resigned as president of the Academy for Health and Lifespan Research after claiming that a supplement developed by a company his brother runs had “reversed” the age of dogs, a claim for which there was so little evidence that one scientist called it a “lie.”

Part of the problem is that scientists still disagree on how to measure aging. And they don’t have a reliable way to measure age reversal, either, should it ever be achieved.

Justice, the XPRIZE director, says a primary purpose of the competition is to solve that problem by encouraging the development of standardized measures of aging. That is so that anti-aging drugs can be assessed reliably, and, one-day, approved by regulators if they work.

 “We as a scientific field have been forced to ask, ‘If a medicine improves how we age, how would we know?” Justice said during a public meeting with FDA officials in May. “If something worked, what would convince us as scientists, what’s meaningful to the general public?”

Finalists in the Healthspan competition will be announced in August.
