Why AI Will Never Replace a Great Teacher | Matt Wu | TED

00:03We're living in the most remarkable moment in the history of education. AI can now tutor you in calculus. It can write you a semester long study plan. I even had one of our students tell me that they instructed their AI to teach computer science the way Gordon Ramsay runs kitchen nightmares.

00:25AI is seriously changing the education game. It's making knowledge more accessible, more personalized, and more intuitive than we ever thought possible. But ask any student what has changed their life the most, and they won't tell you about a technology.

00:41They'll tell you about a person. A teacher who believed in them before they believed in themselves, a friend who kept showing up even when things got hard. a mentor who saw their potential before they could see it themselves. We're investing billions into making sure we put the very best AI tools onto every screen on the planet.

01:05But with all this technology at our fingertips, why aren't we investing just as urgently into making sure every student can connect with the people who will change their life? I've been grappling with this question quite a bit over the last four years while working on something called peer tutoring.

01:26It's a simple concept. Students teaching other students. Imagine any classroom that you've ever been in, right? 20 students all learning the same thing. A concept might click for one student but trip up another. Now, if you match those two students, something beautiful happens.

01:44one tutors the other. The tutor builds confidence and reinforces their own learning. The learner gets personalized support from someone who just figured it out themselves. This peer tutoring concept is the foundation of Schoolhouse, the nonprofit I lead that connects high school students around the world for peer tutoring over Zoom.

02:10Today, nearly 200,000 students have received tutoring from 30,000 incredible volunteer tutors, adding up to over 100 million minutes of learning, all completely for free. And so, as AI reshapes this world around us, I believe that our need for the genuine human connection has never mattered more.

02:35And I've seen proof in the most unexpected places that we can build it, scale it, and change lives with it. This man lost his father when he was in high school and dropped out to support his family. His name is Carl, and for his entire adult life, he hid the fact that he had never graduated until at 52 when he decided to go back for his high school diploma.

03:05But Carl needed help. Algebra terrified him. And so he looked to Schoolhouse for a tutor. Across the country, Sachin, a 14-year-old in the Bay Area, signed up for Schoolhouse to help out other kids his age. He certainly wasn't expecting Carl, who is noticeably not his age, in his first tutoring session, but he quickly realized that Carl was someone he could help.

03:34Every Sunday for over a year, they showed up for tutoring. An adult learner in Mississippi, a teenager in California. And yeah, Carl was learning algebra, but more importantly, he was learning to believe in himself again. Here they are just one week before Carl's exam.

03:54That's P multiplied by two, right? Yeah. No, no, no, no, no, no. It's P / two. All right. Well, let's see. There you go, N Carl. Nice job. All right then, Sachs. Thank you. How are you feeling? How do you think you're going to do on the real test?

04:10My confidence begin to kick in. I can't get weak and agile now. Yeah, they're awesome. Carl took his exam and he scored highest in algebra, the subject that once terrified him. Here's what sticks with me about that story, though. Carl was 14 when he dropped out.

04:36The exact same age as Sachin. If Carl had had a Sachin when he was 14, we could be looking at a very different life trajectory. We talk a lot about making sure students can get access to the right tools and the right technology, but we also need to make sure that every student can access a Sachin.

04:53Someone who can provide the connection and motivation that only another human can. Along the way, we discovered something else. We saw that this peer tutoring wasn't just teaching students how to learn concepts. It was also teaching them how to better understand one another.

05:14This realization led us to create a new program called dialogues where we would pair students who had differing perspectives on often complex or controversial issues like immigration or gun control or abortion. There was no moderator, no script, just two students talking over Zoom.

05:30And I'll be honest, I was kind of skeptical at first. For example, we were going to be pairing Joseph in China with Brian in America to discuss free speech versus hate speech. Like, what could possibly go wrong? But luckily, we were able to get permission to share a few highlights from these conversations.

05:50Uh, let's take a look in China. Free speech. It's not something that people participated with. I think if a politician does use hate speech, then I'll show at the voting booth. I learned a lot today. I've I've had to consider things I never would have otherwise considered.

06:09Friends know I don't talk about politics. I think like humility is so important when coming into these issues. I may be wrong. You know, I need to do my research. I was I was born in India. There it's a very like very rough income inequality.

06:24How would they feel like saying some of their equity from the business they built up just has to be taxed away to some person they barely know? And I think you genuinely changed my mind. This was such a wonderful conversation. You you kept bringing in like your science nerd knowledge.

06:47It's striking to me just how genuine these conversations are. Students show up with passion and conviction and then they do the thing that many adults are starting to forget how to do. They listen. Brian said it perfectly. He had to consider what he's otherwise never had to consider.

07:08That is what makes education human. Not just the transfer of knowledge, but the ability to understand others and use that to shape your own perspective. It can only happen when there's another human on the other end. And it's on us to make sure that every student can engage meaningfully with those who see the world differently.

07:28I've been able to see the impact of this human connection, but often in contexts that were hard to scale. In college, I tutored for a program called Amphibious Achievement, where we taught Boston public students how to row crew and prep for the SAT.

07:44That's what we were doing on the surface. But our main goal was actually to help every student build an unrelenting belief in themselves. And if you're wondering why belief, well, belief is in every student. It takes a lot of hard work to unlock.

07:58But once it's there, it can completely change what a student believes is attainable. And so I saw when my belief in a student would become their belief in themselves. I would see it take root. First as a rowing personal best and then as a college acceptance letter.

08:15And soon you would see that student's entire personality come to life. But I also saw the limitations of this program model where there would be students that we want to help but the proximity or the timing or the number of tutors just wasn't there.

08:35But see, that's what's so unique about this peer model. It can scale. Every phone or laptop becomes a portal to a trusted human. At a global level, students can learn around the clock. And we were surprised to discover that the solution to our tutor shortage was actually right in front of us in our very own learners, right?

08:58Because once a student masters the material, they can go on and teach it to somebody else. And we're seeing that already with one in five of our tutors actually starting their schoolhouse journey first as a learner. The most exciting part about all of this is that institutions are starting to see the value of peer tutoring, too.

09:20We had a student in rural Arkansas, first generation, looking for a way to explore his passion in teaching. He found Schoolhouse and he ran with it, tutoring over 150 sessions in algebra, pre-calc, the SAT, and he was consistently rated in the top 5% by his peers.

09:39All of his contributions showed up on his schoolhouse portfolio, which he submitted in college applications. Now, when admissions officers saw this, they didn't just see a letter grade. They saw proof of something deeper. That the student was adaptable.

09:57That he could help others in a way that was warm and patient and engaging. And that he had already solved real problems with students from 40 other countries. His name is Emanuel. He's at the University of Chicago now and he recently told me that he wants to build his own education startup to pay it forward.

10:15Yeah, everyone's talking about the skills that AI is going to replace. But the skills Emanuel demonstrated, the ability to care, to collaborate, to communicate, these are deeply human skills. They've always been important, but in the age of AI, they are the skills of the future.

10:40And this doesn't just end with college admissions. We're hearing the exact same thing from employers. The skills that they need most are the ones that you cannot automate. All of these stories are proof of what's possible when the authentic human connection is made accessible to everyone.

11:00But every year we graduate another class of students and every year AI gets exponentially more powerful. If the goal is to optimize productivity then yeah AI will win. But if we aspire to build a better society then we must deliver the human connection and develop the human skills that our young people are going to increasingly need.

11:23That is how we navigate the AI revolution in education to create a more connected world, more capable students, and a more human future. Thank you.
