More from The Roots of Progress
I don’t use AI to draft my writing. These are fine handcrafted artisanal essays, every word placed individually with loving care. I use AI a lot for researching, occasionally for brainstorming, and increasingly for fact-checking. But not for outlining, drafting, or directly editing. This isn’t some principled objection to AI use, or a revulsion at the idea of letting technology intrude on my craft. It has simply never occurred to me to do it. Why? I just don’t think AI writing is good enough today. It’s good at research reports or letters to Congressmen or anything else generic. It isn’t compelling enough to make a good blog post. And it certainly doesn’t have my voice or unique point of view. (I don’t think any AI today has a real point of view.) Here’s an example. In revising “The Progress Agenda” for publication as a chapter in my forthcoming book, I wanted to add a paragraph on immigration. Here was my process. First, in my notes, I wrote down several points I might want to make about immigration, off the top of my head. From that, I wrote a simple structure for the paragraph: immigration is good/important but it is difficult/time-consuming/uncertain so we should make it easier (need examples) At that point I needed data and examples to substantiate these points, which I didn’t have off the top of my head. This is where I turned to AI. I started with the promprt “What are some examples or data points to substantiate the idea that immigration, particularly high-skilled immigration, is important to the US?” I had a conversation with it from there, checking out the sources it pointed me to and asking followup questions until I felt I understood each point well. You can read the whole thing here. Once I had enough material, I went back and summarized what I felt were the most relevant points in my notes, with sources. Then I drafted the paragraph. Here’s what I ended up with (at the end of a section calling for across-the-board regulatory reform): Progress in all of these areas depends on talent, and in the US, a lot of that talent comes through immigration. Immigrants are about 14% of the population, but 43% of doctorate-level scientists & engineers. Immigrants or their children co-founded nearly half of the Fortune 500 list as of 2025, including Amazon, Apple, Google, and NVIDIA, and more than half of US billion-dollar startups, including Stripe, Instacart, and Notion. But we restrict our supply of talent through a slow and burdensome immigration process. The H-1B visa used by many STEM workers is capped at a level far below demand: in 2026, there were almost 339,000 applicants, but only 35% of them were selected. The selections are done by lottery. Once here, the path to permanent residency can be epic, particularly for some nationalities: as of April 2026, some Indians even in the second-highest employment-based preference category (professionals with advanced degrees or “persons of exceptional ability”) have been waiting around 12 years for their green cards. And despite the exceptional success of immigrant entrepreneurs, the US has no startup visa. For the sake of national prosperity and security, the US should have more visas and green cards, including an entrepreneur visa; the ones we have should be better targeted to need, not assigned randomly; and processing should be made more efficient, to eliminate decade-long backlogs. That paragraph isn’t going to win me a Pulitzer, but it’s solid and it does its part in the overall essay. As an experiment, after I wrote this, and without showing it to ChatGPT, I prompted it: Given all this discussion, please draft a paragraph on immigration, arguing that 1. immigration is good/important, 2. but it is difficult/time-consuming/uncertain, 3. so we should make it easier (examples). I want to insert it into this essay, near the end of the first major section, on law/regulation: https://newsletter.rootsofprogress.org/p/the-progress-agenda Here’s what it wrote: Immigration is another area where law and regulation need reform. For over a century, the United States has benefited enormously from immigrants, who have contributed disproportionately to science, engineering, entrepreneurship, and economic growth. Many of our most important technology companies were founded or co-founded by immigrants, and immigrants are heavily overrepresented among PhDs, inventors, and startup founders. Yet our system for admitting and retaining high-skilled talent is slow, cumbersome, and irrational. We educate foreign students in our universities, then subject them to visa lotteries, years-long backlogs, and administrative obstacles if they want to stay and build here. The result is that we needlessly turn away scientists, engineers, and founders, or trap them in long periods of uncertainty, even as we complain of labor shortages and worry about national competitiveness. We should make it far easier for talented people to come to America and remain here: expand and streamline visas for high-skilled workers and entrepreneurs, staple green cards to advanced STEM degrees earned at US universities, recapture unused employment-based green cards, reduce or eliminate per-country caps that create absurd backlogs, and generally treat the attraction of global talent as a national advantage rather than a problem to be managed. I don’t like this nearly as much. It’s more bland and less interesting. The main difference that leaps out at me is that my version wove in many more specific stats and examples. The ChatGPT version stays abstract. I’m sure I could prompt or train a model to write more like me. It would be an interesting exercise to see how many rounds of editorial feedback you’d need to give in order to get it to produce a paragraph much closer to mine (maybe only one or two?), or whether you could come up with a general style guide or set of skills that would get it to produce better writing the first time. (In the general case, it would have to be much more than “include specific numbers and examples,” because this paragraph is not one that shows off my unique voice.) I am unmotivated to tinker with this. Frankly, I’m kind of a diva about my writing. I don’t co-author with other people (I kind of dread the idea). I almost never allow guest posts on my blog. I don’t even let other people write social media posts for me. I flatter myself that my voice is inimitable. When someone sends me a draft of something that is supposed to come from me, more often than not I just rewrite it completely. (In contrast, I’m very happy to have AI write code for me.) There’s also the fact that when I publish any writing under my own name, I feel that I am taking on a sacred responsibility. Any writing in my name has to be correct, to the best of my knowledge and ability. It has to not only say true things, it has to select the most important things to include, and take the most interesting and illuminating angles on them. When I sign a piece, I’m not just taking responsibility for errors, I’m taking responsibility for the entire worldview and perspective that gave rise to the piece. And I simply can’t do that unless I wrote it. And the writing process does more than just produce a piece of writing. I learn a lot from researching, outlining, drafting, and revising, and the knowledge and worldview that is built up in my head through that process is part of the outcome. What I learn helps me decide what to research and write about next, serves as examples in future essays, and provides the substance of interviews that I give. Even if I could crank out perfect essays using AI, I couldn’t be a public intellectual that way. If I did have a way to produce truly excellent writing with AI, I might publish it, but not with my name as the author. My role then would not be author but editor. This is, indeed, the future I predicted for writers, and it might be a direction I go in the future. But if I do, you’ll know. It’ll be right there in the byline.
I was invited to speak at the Festival of Progressive Abundance, a conference to rally around “abundance” as a new direction for the political left. This is a writeup of what I said: my message to the left. Thank you for having me—it’s great to be here. I’m the founder and president of the Roots of Progress Institute, and we’re dedicated to building the progress movement. There’s a lot of overlap between the progress movement and the abundance movement—a lot of shared vision and goals, and a lot of the same people are involved. So I was invited here to talk about progress and how it’s relevant to abundance. I agreed to come, because I love abundance. I love it as a vision and a goal. And I love it as a direction for the Democratic party and for the political left. The left styles itself the party of science. That’s good, because abundance needs science, in the long term. But it’s not enough: abundance also needs technology and economic growth. Technology and growth are historically how we have created the abundance we already enjoy. Abundance, after all, is relative, and we have a lot compared to the past. We should always remember how lucky we are to live today instead of 200 years ago—when homes didn’t have electricity, refrigerators, or toilets; when almost no vaccines existed to protect us from disease; when a room like this would have been lit not with clean electric lights but with smelly, polluting oil lamps; when a gathering like this would in fact have been impossible, because to travel across the country was not a six-hour plane flight, but a six-month trek by horse and wagon, Oregon Trail style. Just as we have abundance compared with the past, we should hope that the future can be just as abundant, compared to the present. Indeed, the recent book Abundance by Ezra Klein and Derek Thompson opens with a imagined scene from a technologically advanced future: energy from solar, nuclear, and geothermal; desalination using microbial membranes; indoor farms where food is grown with light from LEDs; lab-grown meat; drone deliveries; longevity drugs made in space-based pharmaceutical plants; supersonic passenger jets; artificial intelligence raising everyone’s productivity so we can all enjoy more leisure. The historic pattern of increasing abundance over time, and the hope and promise of an even more abundant future, is what used to be commonly known as progress. Progressives used to believe in progress. The old left was not just the party of science—it was a party of science, technology, and growth. Take Teddy Roosevelt—a progressive if there ever was one. One of the signature achievements of his administration was the Panama Canal. This was a massive engineering project, a triumph of hydraulic engineering technology, celebrated at the time as the 13th Labor of Hercules. When FDR launched the New Deal, one of his signature projects was the Tennessee Valley Authority, which created hydroelectric dams to provide electricity for an entire region. And JFK, of course, is the president who called for putting a man on the Moon—one of the greatest technological achievements not just of its era, but of all time. When JFK gave his famous speech about the Apollo program (the one where he said “we choose to go to the Moon”), he put it in the context of the grand story of human progress. He invoked that narrative to inspire the people and justify his aims. The Moon landing, in 1969, was a peak moment for America: literally the highest we had ever reached. But after that, something changed. The children of the ‘60s were starting to see technology and growth as responsible for some of the worst problems of the 20th century, such as environmental damage and the horrors of war. Growth had created pollution and acid rain. Technology had created machine guns, chemical weapons, and the atomic bomb. But instead of just being anti-pollution and anti-war, the new left decided to become anti-technology and anti-growth. And so a party of science, technology, and growth became just a party of science. That was a mistake, a costly historical error that we should now correct. What has 50 years of the anti-growth mindset gotten us? Stagnation and sclerosis. We can’t build anything in this country anymore. We can’t build the homes we need to make our cities affordable. We can’t build the transit we need to make those cities livable. We can’t build energy infrastructure, either generation or the power lines to connect it to the grid. Without economic growth, we don’t have the engine that raises the standard of living for everyone and helps people lift themselves out of poverty. Without growth, people feel they are playing a zero-sum game—and they turn to exclusion. “No, you can’t move to my neighborhood, it’s too crowded.” “No, you can’t immigrate, you’re going to steal my job.” We want abundance thinking instead: “Yes, move to my neighborhood—we’ll build more homes!” “Yes, immigrate here—there’s so much work to be done, we need all the help we can get.” I think people have grown weary of the anti-growth mindset, weary of stagnation and sclerosis. So I’m glad to see that abundance is now a politically winning issue. And I would love to see it be a new direction for the left. But the right is also moving to embrace technology and growth—or rather, they’re doing that with one hand, while fighting those things with the other. On the one hand, they’ve embraced technologies like nuclear power, supersonic flight, and AI. On the other hand: They’re fighting vaccines, one of the greatest technologies ever invented. They’re defunding research into mRNA, one of the most promising genetic engineering techniques. They’ve disrupted research funding broadly. They’ve disrupted immigration, including high-skilled immigration, which is one of our best talent pipelines into R&D. And they’ve put tariffs on everything, which almost any economist will tell you is hurting affordability and slowing growth. So the right has at best a mixed record on abundance. The left can still be the party of abundance, if it wants to be. But it won’t be easy. It will be uncomfortable. Because to become the party of abundance requires truly embracing technology and growth—and the left has developed an allergic reaction to those things. So there’s some work to be done: some lessons to be unlearned, some old habits to be broken. But I’m excited to help with that work, and I invite you to talk to me about it. I’m eager to see the party of science become once again a party of science, technology, and growth. And I look forward to the day when progressives once again believe in progress. PS: I would also like to see the right become, more consistently, the party of abundance. I would like to see both parties competing to be the party of abundance! At some point I may write up an analogous “message to the right.”
I get a lot of pushback to the idea that humanity can “master” nature. Nature is a complex system, I am told, and therefore unpredictable, uncontrollable, unruly. I think this is true but irrelevant. Consider the weather, a prime example of a complex system. We can predict the weather to some extent, but not far out, and even this ability is historically recent. We still can’t control the weather to any significant degree. And yet we are far less at the mercy of the weather today than we were through most of history. We achieved this not by controlling the weather, but by insulating ourselves from it—figuratively and literally. In agriculture, we irrigate our crops so that we don’t depend on rainfall, and we breed crops to be robust against a range of temperatures. Our buildings and vehicles are climate-controlled. Our roads, bridges, and ports are built to withstand a wide range of weather conditions and events. Or consider an extreme weather event such as a hurricane. Our cities and infrastructure are not fully robust against them, and we can’t even really predict them, but we can monitor them to get early warning, which gives us a few days to evacuate a city before landfall, protecting lives. Or consider infectious disease. This is not only a complex system, it is an evolutionary one. There is much about the spread of germs that we can neither predict nor control. But despite this, we have reduced mortality from infectious disease by orders of magnitude, through sanitation, vaccines, and antibiotics. How? It turns out that this complex system has some simple features—and because we are problem-solving animals endowed with symbolic intelligence, we are able to find and exploit them. Almost all pathogens are transmitted through a small number of pathways: the food we eat, the water we drink, the air we breathe, insects or other animals that bite us, sexual contact, or directly into the body through cuts or other wounds. And almost all of them are killed by sufficient heat or sufficiently harsh chemicals such as acid or bleach. Also, almost none of them can get through certain kinds of barriers, such as latex. Combining these simple facts allows us to create systems of sanitation to keep our food and water clean, to eliminate dangerous insects, to disinfect surfaces and implements, to equip doctors and nurses with masks and gloves. For the infections that remain, it turns out that a large number of bacterial species share certain basic mechanisms of metabolism and reproduction, which can be disrupted by a small number of antibiotics. And a small number of pathogens once caused a large portion of deaths—such as smallpox, diphtheria, polio, and measles—and for these, we can develop vaccines. We haven’t completely defeated infectious disease, and perhaps we never will. New pandemics still arise. Bacteria evolve antibiotic resistance. We can sanitize our food and water, but not our air (although that may be coming). But we are far safer from disease than ever before in history, a trend that has been continuing for ~150 years. Even if we never totally solve this problem, we will continually make progress against it. So I think the idea that we can’t control complex systems is just wrong, at least in the ways that matter to human existence. Indeed, a key lesson of systems engineering is that a system doesn’t need to be perfectly predictable in order to be controllable, it just has to have known variability.1 We can’t predict the next flood, but we can learn how high a 100-year flood is, and build our levees higher. We can’t predict the composition of iron ore or crude oil that we will find in the ground, but we can devise smelting and refining processes to produce a consistent output. We can’t predict which germs will land on a surgeon’s scalpel, but we know none of them will survive an autoclave. So we can tame complex systems, and achieve continually increasing (if never absolute or total) mastery over nature. Our success at this is part of the historical record, since most of progress would be impossible without it. The “complex system” objection to the goal of mastery over nature simply doesn’t grapple with these facts. Eric Drexler makes this point at length in Radical Abundance. ↩

Many technologies can be used in both healthy and unhealthy ways. You can indulge in food to the point of obesity, or even make it the subject of anxiety. Media can keep us informed, but it can also steal our focus and drain our energy, especially social media. AI can help students learn, or it can help them avoid learning. Technology itself has no agency to choose between these paths; we do. This responsibility exists at all levels: from society as a whole, to institutions, to families, down to each individual. Companies should strive to design healthier products—snack foods that aren’t calorie-dense, smartphones with screen time controls built in to the operating system. There is a role for law and regulation as well, but that is a blunt instrument: there is no way to force people to eat a healthy diet, or to ensure that students don’t cheat on their homework, without instituting a draconian regime that prevents many legitimate uses as well. Ultimately part of the responsibility will always rest with individuals and families. The reality, although it makes some people uncomfortable, is that individual choices matter, and some choices are better than others. I am reminded of a study on whether higher incomes make people happier. You might have heard that more money does not make people happier past an annual income of about $75k. Later research found that that was only true for the unhappiest people: among moderately happy people, the log-linear relationship of income to happiness continued well past $75k, and in the happiest people, it actually accelerated. So there was a divergence in happiness at higher income levels, a sort of inverse Anna Karenina pattern: poor people are all alike in unhappiness, but wealthy people are each happy or unhappy in their own way. This matches my intutions: if you are deeply unhappy, you likely have a problem that money can’t solve, such as low self-esteem or bad relationships; if you are very happy, then you probably also know how to spend your money wisely and well on things you will truly enjoy. It would be interesting to test those intuitions with further research and to determine what exactly people are doing differently that causes the happiness divergence. Similarly, instead of simply asking whether social media makes us anxious or depressed, we should also ask how much divergence there is in these outcomes, and what makes for the difference. Some people, I assume, turn off notifications, limit their screen time, put away their phones at dinner, mute annoying people and topics, and seek out voices and channels that teach them something or bring them cheer. Others, I imagine, passively submit to the algorithm, or worse, let media feed their addictions and anxieties. A comparative study could explore the differences and give guidance to media consumers. In short, we should take an active or agentic perspective on the effects of technology and our relationship to it, rather than a passive or fatalistic one. Instead of viewing technology as an external force that acts on us, we should view it as opening up a new landscape of choices and possibilities, which we must navigate. Nir Eyal’s book Indistractable is an example, as is Brink Lindsey’s call for a media temperance movement. We should also take a dynamic rather than static perspective on the question. New technology often demands adjustments in behavior and institutions: it changes our environment, and we must adapt. For thousands of years manual labor was routine, and the greatest risk of food was famine—so no one had to be counseled to diet or exercise, and mothers would always encourage their children to eat up. Times have changed. These changes create problems, as we discover that old habits and patterns no longer serve us well. But they are better thought of as growing pains to be gotten through, rather than as an invasion to be repelled. When we shift from a static, passive framing to a dynamic, agentic one, we can have a more productive conversation. Instead of debating whether any given technology is inherently good or bad—the answer is almost always neither—we can instead discuss how best to adapt to new environments and navigate new landscapes. And we can recognize the responsibility we all have, at every level, to do so.
More in science
Is philosophy real? We sent our correspondent to find out.
Stephen J Gould (still my favorite science essayist) wrote an excellent article in 1985 (Red Wings in the Sunset, later published in his book, Bully for Brontosaurus) about artist and naturalist Abbott Handerson Thayer. Thayer wrote about how animals use coloration as camouflage – what he called “cryptic coloration”. His ideas were solid, but he made a classic mistake that scientists sometimes make, overapplying their key discovery. Thayer argued that all animal coloration is cryptic. For example, he argued that flamingos are pink because it hides them in the setting sun (hence the title of the essay). This is a transparently absurd argument, and it shows how Thayer tried to shoehorn all evidence into his preferred and absolute narrative. It is better to assume that nature is complex, and all explanations are at best partial (unless proven otherwise). Animal coloration, in fact, can serve many different purposes, only one of which is camouflage. Thayer also struggled with the male peacock, for example. Butterflies appear to be another example. Actually, many butterflies are camouflaged on the underside of their wings, so that when they are at rest with their wings up they tend to blend into their surroundings. But the top side of their wings are often very colorful and not camouflaged at all. One assumption is that the brightly colored part of their wings is to attract mates. This may be true, but that does not mean the coloration does not serve another function. Often animals use visual cues when choosing their mates that are markers for health and success. As evidence that butterfly wing color may be serving a survival benefit, if you look at birds that feed on insects during flight, they target dully-colored moths much more than brightly colored butterflies, even though the butterflies should be easier to see. A recent study tests the hypothesis that the brightly colored and patterned top side of butterfly wings may have evolved to produce an optical illusion to confuse predators. The idea of using optical illusions as visual protection in animals is not new. For example, zebra stripes allow zebras to hide in the herd, confusing predators as to where one zebra ends and another begins. Stripes on zebras and snakes may also serve to confuses predators about their direction of motion, but this hypothesis has not been tested previously. The researchers started by filming butterflies taking off using high speed cameras. They found that the wing patterns created a powerful “barber pole” illusion. The stripes on a barber pole look like they are moving up or town even when the pole is just spinning. Similarly, the wing patterns combined with the way butterflies move their wings and their flight dynamics combine to create a similar barber pole illusion, making the butterfly look like it is moving down when it is in fact moving up. They also showed that this strategy is phylogenetically widespread. They then did modeling in silico and showed digital creatures converge on butterfly-like patterns. To understand how effective this strategy can be it’s important to understand how catching a butterfly in midflight works. Butterflies have a very jumpy pattern of flight. In order to grab them in flight, a bird will have to zero in on their exact location with a few hundred millisecond and millimeter precision. If the butterfly suddenly zigs while the bird perceives that they zagged, the birdy will miss. Alternatively they may make only a glancing blow or grab an edge of a wing rather than their body. Either way, the butterfly lives another day and the bird goes hungry. In zebras this effect has been referred to as the “visual dazzle” strategy. Now there is some empiric evidence that this works not just by confusing predators, but by creating a specific optical illusion. Zebras will also zig-zag to evade predators, and misjudging that last second movement can cause a pouncing lioness to miss. There are two specific illusion effects at work – the aperture effect and spatiotemporal aliasing. The aperture effect refers to the brain’s processing of visual information through a limited field of view. The visual system has a hard time processing many moving stripes, and specifically will confuse the direction of movement (this is the barber pole effect). So a predator may miss a zebra’s vertical movement, for example, and perceive all movement as perpendicular to the stripes. They may also misinterpret the angle of movement and only perceive the perpendicular motion. Spatiotemporal aliasing has to do with ratio of the movement with the “refresh” speed of the brain’s visual processing. You have likely seen this with spinning wheels that have spoke-like features. As the wheel slows down, at one point the spinning will appear to stop completely, and then will appear to spin backwards. This is simply an artifact of your brain’s visual processing speed. Now imagine being surrounded by a field of rapidly moving and zig-zagging stripes, and your brain trying to make sense of all this information, while trying to compensate for these powerful optical illusions. Butterflies don’t have a herd to hide in, but they do have the added element of their flapping wings. Not only are they moving in a way to maximize these optical illusions, their wings are also doing this, while alternating top-side and bottom-side. Some butterflies have bright spots on their colorful upper wings, that will flash as they flap their wings, causing another type of dazzling disorientation. I will end by returning to my original point – do not be limited in the types of explanations that you reach for when trying to understand nature. Nature is not so limited. Animals do not just use coloration for camouflage and attracting mates. They can also use their coloring for thermoregulation, for mimicking other animals, for producing a danger-signal to would-be predators, and to communicate with other members of their species. It can communicate mood, danger, or social status. Now we have to add optical illusions to the list. There may be other strategies yet to be discovered or imagined.
