AI in the Classroom Can Make Higher Education Much More Accessible

For some school subjects, artificial intelligence can transform the landscape of tutoring accessibility.

Summary: ChatGPT4 has demonstrated superiority in various student exams, revealing its potential to support academic learning and improve educational outcomes, particularly in test preparation. With its accessibility and affordability compared to traditional tutoring services, AI tutoring can help address the increasing demand for academic support, especially as universities begin to reinstate standardized testing requirements.


In 2023, OpenAI shook the foundation of the education system by releasing ChatGPT4. The previous model of ChatGPT had already disrupted classrooms K–12 and beyond by offering a free academic tool capable of writing essays and answering exam questions. Teachers struggled with the idea that widely accessible artificial intelligence (AI) technology could meet the demands of most traditional classroom work and academic skills. GPT3.5 was far from perfect, though, and lacked creativity, nuance, and reliability. However, reports showed that GPT4 could score better than 90 percent of participants on the bar exam, LSAT, SAT reading and writing and math, and several Advanced Placement (AP) exams. This showed a significant improvement from GPT3.5, which struggled to score as well as 50 percent of participants.

This marked a major shift in the role of AI, from it being an easy way out of busy work to a tool that could improve your chances of getting into college. The US Department of Education published a report noting several areas where AI could support teacher instruction and student learning. Among the top examples was intelligent tutoring systems. Early models of these systems showed that an AI tutor could not only recognize when a student was right or wrong in a mathematical problem but also identify the steps a student took and guide them through an explanation of the process.

The role of tutoring in education has grown in significance as more and more high school students have gone to college. Private tutoring is now a booming industry. Often you can find tutors charging anywhere up to $80 for test preparation with no shortage of eager parents willing to pay for their services. Tutoring has been a go-to solution for students to improve their grades outside the classroom. But more importantly, it has been a solution to improve their chances of getting into college, with many private tutoring services focusing on AP and SAT exams. This connection between college admission success and private tutoring costs has been a problem for parents who cannot afford the costs.

ChatGPT4 is available for $20 a month. Although the program itself can be used to answer questions and provide academic support, dedicated education websites have begun incorporating AI tutors to help with test prep. Khan Academy provides free courses on AP content and SAT exams and offers an AI-powered tutor for these subjects at $4 a month. Duolingo, a popular language learning app that offers university-recognized language exams, offers Duolingo Max at $14 a month. These tutoring services are accessible at your fingertips at any time. There is no need to schedule video conferencing calls, do background checks on tutors, or pay extra costs. Quality individualized academic support is available at a moment’s notice.

The availability of AI tutoring services is occurring at a crucial moment in education. As students become accustomed to post-pandemic life, student achievement across the nation still has not returned to where it once was. Despite that, many universities have begun reversing test-optional policies that had allowed students to avoid taking standardized tests such as the SAT. The demand for tutoring has skyrocketed as many new high school seniors struggle to meet the old standards of college admissions. Many school tutoring programs have not been able to provide the support students need, and private tutoring costs are only increasing.

AI has the potential to provide cheap and effective tutoring for these exams while being easily accessible. A Harvard computer science course has been able to incorporate ChatGPT to great success, using it to provide continuous and customized technical support and allowing professors to focus more on pedagogy. As technology improves, students will have more support for academic pursuits, opening an easier path to higher education but also allowing students to more easily explore academic interests beyond rigid classroom instruction.

Climate Litigation Can’t Fix the Past, but It Can Hinder the Future

Dealing with climate change requires technological innovation and economic growth, not legal warfare between nations.

Summary: The International Court of Justice has suggested nations could be held liable for historic greenhouse gas emissions, opening the door to lawsuits over centuries of industrial activity. Yet this approach risks punishing the very innovations that lifted billions out of poverty and advanced human health and flourishing. Lasting progress on climate challenges will come not from courtroom battles, but from technological solutions and continued economic development.


The International Court of Justice’s advisory opinion purporting to establish legal grounds that would allow nations to sue one another over climate damages represents judicial overreach that ignores economic history and threatens global development. While the opinion was undeniably legally adventurous, the framework it envisages would be practically unworkable as well as economically destructive.

The ICJ’s ruling suggests countries can be held liable for historical emissions of planet-warming gases. That creates an accounting nightmare that no legal system can resolve. How does one calculate damages from coal burned in Manchester in 1825 versus emissions from a Beijing power plant in 2025? How does one stack up the harm caused by a warming world against the benefits of industrialization?

Britain began large-scale coal combustion during the Industrial Revolution, when atmospheric CO2 concentrations were 280 parts per million and climate science did not exist. Holding Britain liable for actions taken without knowledge of consequences violates basic principles of jurisprudence. The same applies to the United States, whose early industrialization occurred during an era when maximizing economic output was considered unambiguously beneficial to human welfare.

Critics of historical emissions ignore what those emissions purchased. British coal combustion powered textile mills that clothed much of the world, steam engines that revolutionized transportation, and factories that mass-produced goods previously available only to elites. American industrialization followed, creating assembly lines, electrical grids, and chemical processes that form the backbone of modern civilization.

These developments were not zero-sum exercises in resource extraction. They created knowledge, infrastructure, and institutions that benefited everyone. The steam engine led to internal combustion engines, which enabled mechanized agriculture that now feeds 8 billion people. Coal-powered steel production made possible skyscrapers, bridges, and the infrastructure that supports modern cities, where most humans now live longer, healthier lives than their ancestors.

The data on human welfare improvements since industrialization began are explicit. Global life expectancy increased from approximately 29 years in 1800 to 73 years today. Infant mortality rates fell from over 40 percent to under 3 percent. Extreme poverty, defined as living on less than $2.15 per day in purchasing power parity terms, declined from over 80 percent of the global population in 1800 to under 10 percent today.

Nutrition improved dramatically. Caloric availability per person has increased by roughly 40 percent since 1960 alone, while food prices relative to wages fell consistently. Height, a reliable indicator of childhood nutrition, increased significantly across all regions. Educational attainment expanded from literacy rates below 10 percent globally in 1800 to over 85 percent today.

These improvements correlate directly with energy consumption and industrial development. Countries that industrialized earliest experienced these welfare gains first, then transmitted the knowledge and technology globally. The antibiotics developed in American and European laboratories now save lives worldwide. The agricultural techniques pioneered in industrialized nations now feed populations that would otherwise face starvation.

The International Court of Justice’s liability framework threatens to undermine the very mechanisms that created these welfare improvements. Innovation requires investment, which requires confidence in property rights and legal stability. If successful economic development subjects countries to retroactive liability, the incentive structure tilts away from growth and toward stagnation.

Consider current developing nations. Under this legal framework, should India or Nigeria limit their industrial development to avoid future liability? Should they forgo the coal and natural gas that powered Western development? That creates a perverse situation where the legal system penalizes the exact processes that lifted billions from poverty.

The framework also ignores technological solutions. The same innovative capacity that created the Industrial Revolution is now producing renewable energy technologies, carbon capture systems, and efficiency improvements that address climate concerns without sacrificing development. Market incentives and technological progress offer more promise than legal blame assignment.

Which emissions count as legally actionable? All anthropogenic CO2 remains in the atmosphere for centuries, making every emission since 1750 potentially relevant. Should liability begin with James Watt’s steam engine improvements in 1769? With the first coal-fired power plant? With Henry Ford’s assembly line? The temporal boundaries are arbitrary and politically motivated rather than scientifically determined.

Similarly, which countries qualify as defendants? The largest current emitters include China and India, whose recent emissions dwarf historical American and British totals. China alone now produces more CO2 annually than the United States and Europe combined. Any coherent liability framework must address current emissions, not just historical ones.

And where would the money go? This aspect of the case was brought up by Vanuatu. If the island nation receives compensation from the UK and the US, should it not be obliged to pay the British and the Americans for a plethora of life-enhancing Western discoveries, including electricity, vaccines, the telephone, radio, aviation, internet, refrigeration, and navigation systems?

Climate adaptation and mitigation require technological innovation and economic growth, not legal warfare between nations. The countries that industrialized first possess the technological capacity and institutional knowledge to develop solutions to today’s problems. Channeling resources toward litigation rather than innovation represents a misallocation that benefits lawyers while harming global welfare.

The ICJ opinion reflects wishful thinking rather than practical policy. Legal frameworks cannot repeal economic reality or reverse the historical processes that created modern prosperity. Instead of seeking retroactive justice for emissions that enabled human flourishing, policymakers should focus on technologies and institutions that sustain development while addressing environmental concerns. The alternative is a world where legal systems punish success and innovation while offering nothing constructive in return.

Growth Comes From Ideas, Not Degrees | Podcast Highlights

Marian Tupy interviews Bryan Caplan about the relationship between formal education and innovation.

Get The Case Against Education here.

I want to start with a broad question. What is economic growth, and where does it come from?

Economic growth is just change in economic well-being. Usually, we measure it with GDP.

Where does it come from? There are a lot of stories that people tell. Traditionally, people said it comes from capital accumulation and better-quality labor. But when you really go to the numbers, neither of these things can explain anywhere close to the full change, so most growth has got to be from technological progress, broadly defined. That is the main difference between the world of today and the world of 2000 years ago.

In your piece, you distill it to a single word: ideas.

That’s right.

Why is economic growth important?

In any given year, it seems like getting another percentage point of growth couldn’t make much difference. You barely even notice it. And yet, as many people have pointed out, when you compound an extra percentage point of growth per year over the course of 100 years, it’s the difference between poverty and riches. And riches are what allow you to buy free time. Riches are what allow you to buy culture, to save your child from worms.

Right. So economic growth is an increase in wealth, it comes from new ideas, and ultimately, it is highly correlated with things like better infrastructure, better hospitals, and so on.

Absolutely.

What is the purported relationship between education and growth?

The normal view is that education is the crucial determinant of growth, that it turns unskilled humans into the skilled workers of the modern economy. This is an idea not just from politicians, teachers, and the general public, but also from economics. If you take a class in economics, they will constantly talk about how it’s important to have lots of education because that’s how we build human capital.

So, the purported relationship is that education creates human capital, which creates new ideas and thus more growth?

That’s one version. The more common one is simply that education leads to human capital, which immediately leads to growth. The typical college grad isn’t going to invent anything, but they’re capable of being a more valuable cog in the machine.

Right, so the standard inference is that if you have a more educated workforce, they can accomplish more sophisticated tasks. What does the evidence show?

So, I have a book called The Case Against Education, and I’m not going to be coy about this: I expected to find that education was overrated. However, I also expected to find that a lot of other people researching would say they had clear evidence that education raises economic growth.

However, when I read all the mainstream work on education, there was a big debate about “how come we’re not finding what we know to be true, which is that education is the crucial cause of economic growth?” I think that they are finding the truth, which is that education isn’t a factory for building human capital, but a certification machine for stamping people: good worker, great worker, not so great worker. People like to think about education as a way of building skills, but actually, it’s more like a passport to the real training, which happens on the job.

So, by going to university, you are offering your employer a sign that you are intelligent and conscientious enough to do so.

You’re showing intelligence, conscientiousness, and also conformity. There’s no “I” in team. Most jobs require you to follow a chain of command to achieve the goal of the group. While on some level I don’t like conformity, on a deeper level it’s really important for most purposes.

I want to read you something that you wrote. “Contrary to conventional stories about the positive externalities of education, mainstream estimates of education’s national rate of return were consistently below estimates of education’s individual rate of return.”

What does that mean?

Great question.

A rate of return is basically a measure of how good an investment is. So, for example, you might try to calculate the rate of return of putting extra insulation on a house. We can do the same for education and figure out how all the costs of education compare to the payoffs.

When you do this from the point of view of an individual person, it’s pretty common to get a 10 percent inflation-adjusted rate of return. In my book, I say this is probably too high, but you can bring it down to maybe 7 or 8 percent.

We can also think about this at the level of the country. What if we raise the education level of the whole workforce of a country by a year? How much does that enrich the country? What that quote is saying is that even the high estimates of how much a year of education does for a country are typically around half of what it does for an individual. And a lot of the estimates find that sending the whole country to school for an extra year increases national income by 1 or 2 percent.

In other words, a stamp is a good way for one person to get ahead in life, but stamping the whole country does not help that country get ahead; it just creates credential inflation. You need more and more degrees in order to get the same job that your parents and grandparents got with fewer.

Let’s talk a little bit about innovation. Where do new ideas come from? Are we talking about a very small group of individuals who share certain characteristics?

It’s an exaggeration to say that innovation only comes from a few people. There are millions of small-scale improvements coming from many different people. Opening a new kind of restaurant is not revolutionary R&D, but so much of the improvement in our living standards comes from these small acts of entrepreneurship. When I was in high school, there were only three kinds of restaurants: American, Italian, and Chinese. Now we have a cornucopia of different cuisines. The same goes for so many other simple products. Dog collars now come in 100 more varieties than they did back when I was growing up in the ’80s.

However, the really revolutionary stuff—new vaccines, new business models, new forms of energy—comes from very special people. I think it’s reasonable to say that almost all the really big ideas are coming out of the top sliver of the IQ distribution. There was a psychologist named Lewis Terman in California who, I believe, in the 1920s, saw that there was a standardized test administered to all the kids in the state of California school system. He managed to get data on the top hundred scorers in the whole state of California in that year, and he followed them through life. In his honor, these kids are named the termites, and there’s been a lot of research on them.

While the vast majority of this group didn’t do anything really impressive, they had many times, maybe a thousand times, the normal rate of stellar success. So, just doing these kinds of tests is a good way of identifying the most promising people. At a minimum, just have a system where you basically let children advance as rapidly as they’re capable of. A lot of very intelligent people feel very isolated from their own age group, and it makes sense just to advance them as far as their talent will take them.

I have a personal view, which is that our society is very open to the idea of the STEM prodigy, but we are very closed to the idea of there being a prodigy in, say, history. And I think that there are history prodigies. I have met kids with not just a broad, but a deep understanding of history by the time they’re 13 or 14. People think it’s crazy to put them in a PhD program in history when they’re 14 years old, but I don’t. Why not skip that kid ahead and let him become a star? Look, maybe he wants to be a regular 12-year-old even though he is a genius, but maybe he doesn’t. Maybe he wants to be with a peer group of geniuses. Let’s pave the way for him if that’s what he wants.

Do you think that AI will allow us to continue innovating if the population starts declining?

There was a long period where people working on AI kept over-promising and under-delivering. I would personally hear extravagant claims and check them out and find that they weren’t true. Finally, about two years ago, they started being correct. I was as shocked as anyone. I actually have a bet out about AI, which I’m probably going to lose. It’s embarrassing because I have otherwise a perfect public betting record.

That said, one incredible achievement does not mean that they’re going to have a whole series of incredible achievements. And there’s a lot to the idea that AI is basically just amazing at compiling what has already been said rather than truly coming up with new stuff. While it’s not impossible for it to get better, a lot better, it’s also not guaranteed.

Another thing worth pointing out is that we’ve had, by many measures, falling rates of innovation despite a rising population. There’s an idea that we’ve already discovered a lot of the low-hanging fruit, and so we need to keep multiplying our efforts to maintain the same rate of growth. Another plausible story is that we have doubled the number of people that we call researchers, but really only the best ones count, and the other ones are kind of fake.

Given that much of the money we spend on education is spent poorly or even counterproductively, what should we do with the money instead?

I’m totally on board with giving it back to the taxpayers or just paying down the national debt. We badly need austerity. We are driving at 100 miles per hour towards a brick wall, but there’s still time to change course and get our foot on the brakes. One of the easiest ways of doing that is by spending less on education.

Is education more useful in the developing world?

Poor countries have a severe problem with teachers even showing up. They, on paper, have many years of education—I think Haiti now is around where France was in 1960—but mostly they are just throwing money at a corrupt system that doesn’t even teach basic literacy and numeracy. The way that people in the third world are learning to use technology is the way that almost all normal people learn anything, which is by doing.

It seems to me that we are doing the exact opposite. We are keeping people in the education system for many years, which could prevent them from starting to work and learning by doing.

Yeah. It would be much better if people started adult life at an earlier age. They’re totally ready for it. There’s no reason why 13- or 14-year-olds should not be working. One of the best ways to get kids to actually learn stuff, especially the kids who hate school, is to make it practical. They need to see concrete results and make money.

If you read biographies or autobiographies of people in earlier eras, it is amazing how far people got at young ages. By the age of 15, Malcolm X had worked four different jobs and been all over the country. Many people listen to me and say, “Oh, that’s so dystopian.” I think the system we have now is dystopian, where someone has to sit in a classroom until they’re 30 listening to some boring windbag talk about things he doesn’t even know how to do.
