The Artificial Intelligence landscape is changing with remarkable speed these days, and the capability of Large Language Models in particular has led to speculation (and hope, and fear) that we could be on the verge of achieving Artificial General Intelligence. I don't think so. Or at least, while what is being achieved is legitimately impressive, it's not anything like the kind of thinking that is done by human beings. LLMs do not model the world in the same way we do, nor are they driven by the same kinds of feelings and motivations. It is therefore extremely misleading to throw around words like "intelligence" and "values" without thinking carefully about what is meant in this new context.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/11/27/258-solo-ai-thinks-different/Support Mindscape on Patreon.Some relevant references:Introduction to LLMs by Andrej Karpathy (video)OpenAI's GPTMelanie Mitchell: Can Large Language Models Reason?Mitchell et al.: Comparing Humans, GPT-4, and GPT-4V On Abstraction and Reasoning TasksKim et al.: FANToM: A Benchmark for Stress-testing Machine Theory of Mind in InteractionsButlin et al.: Consciousness in Artificial Intelligence: Insights from the Science of ConsciousnessMargaret Boden: AI doesn't have feelingsSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Putting on clothes is one of the most universal human experiences. Inevitably, this involves choices; maybe you just grab the cheapest and most convenient clothing available, or maybe you want to fit seamlessly into your local environment, whatever that might be. But maybe you choose to dress more consciously, putting a bit of effort into crafting a personal style and creating a desired impression in others. Derek Guy has, to his own surprise, become well-known as the menswear guy on Twitter. He has put a lot of thought into both the practicalities of clothing (how to find a suit that fits) and its wider social impact (how fashion acts as a cultural language). We talk about both sides of the coin.(Picture on right is not Derek, but rather former US Attorney General Elliot Richardson, whose dapper image Derek uses as his avatar.)Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/11/20/257-derek-guy-on-the-theory-and-practice-of-dressing-well/Support Mindscape on Patreon.Derek Guy is a fashion writer living in San Francisco.

There is an undeniable romance in the idea of traveling to, and even living in, outer space. In recent years, a pragmatic justification has become increasingly popular: the Earth is vulnerable to threats both natural and human-made, and it seems only prudent to spread life to other locations in case a disaster befalls our home planet. But how realistic is such a grand ambition? The wife-and-husband team of Kelly and Zack Weinersmith have tackled this question from a dizzying number of angles, from aeronautics and biology to law and psychology.

A "Theory of Everything" is physicists' somewhat tongue-in-cheek phrase for a hypothetical model of all the fundamental physical interactions. Of course, even if we had such a theory, it would tell us nothing new about higher-level emergent phenomena, all the way up to human behavior and society. Can we even imagine a "Theory of Everyone," providing basic organizing principles for society? Michael Muthukrishna believes we can, and indeed that we can see the outlines of such a theory emerging, based on the relationships of people to each other and to the physical resources available.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/10/30/255-michael-muthukrishna-on-developing-a-theory-of-everyone/Support Mindscape on Patreon.Michael Muthukrishna received his Ph.D. in psychology from the University of British Columbia.

It can be tempting, when first introduced to a deep concept of physics like Heisenberg's uncertainty principle, to draw grand philosophical conclusions about the impossibility of knowing anything precisely. That is generally a temptation to be resisted, just because it's so easy to do it wrong. But there is absolutely a place for a careful humanistic synthesis of these kinds of scientific ideas with other ideas, for example from philosophy or literature. That's the kind of task William Egginton takes on in his new book The Rigor of Angels, which compares the work of philosopher Immanuel Kant, physicist Werner Heisenberg, and author Jorge Luis Borges, three thinkers who grappled with limitations on our aspirations to know reality directly.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/10/23/254-william-egginton-on-kant-heisenberg-and-borges/Support Mindscape on Patreon.William Egginton received his Ph.D. in Comparative Literature from Stanford University.

David Deutsch is one of the most creative scientific thinkers working today, who has as a goal to understand and explain the natural world as best we can. He was a pioneer in quantum computing, and has long been an advocate of the Everett interpretation of quantum theory. He is also the inventor of constructor theory, a new way of conceptualizing physics and science more broadly. But he also has a strong interest in philosophy and epistemology, championing a Popperian explanation-based approach over a rival Bayesian epistemology. We talk about all of these things and more, including his recent work on the Popper-Miller theorem, which specifies limitations on inductive approaches to knowledge and probability.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/10/16/253-david-deutsch-on-science-complexity-and-explanation/Support Mindscape on Patreon.David Deutsch received his Ph.D. in theoretical physics from the University of Oxford.

Our planet and its environment are in bad shape, in all sorts of ways. Those of us who want to improve the situation face a dilemma. On the one hand, we have to be forceful and clear-headed about how the bad the situation actually is. On the other, we don't want to give the impression that things are so bad that it's hopeless. That could -- and, empirically, does -- give people the impression that there's no point in working to make things better.

Biological organisms are paradigmatic emergent systems. That atoms of which they are made mindlessly obey the local laws of physics; even cells and organs do their individual jobs without explicitly understanding the larger whole of which they are a part. And yet the system as a whole functions beautifully, with apparent purpose and function. How do the small parts come together to form the greater whole?

The study of cognition and sentience would be greatly abetted by the discovery of intelligent alien beings, who presumably developed independently of life here on Earth. But we do have more than one data point to consider: certain vertebrates (including humans) are quite intelligent, but so are certain cephalopods (including octopuses), even though the last common ancestor of the two groups was a simple organism hundreds of millions of years ago that didn't have much of a nervous system at all.

Over the last year, AI large-language models (LLMs) like ChatGPT have demonstrated a remarkable ability to carry on human-like conversations in a variety of different concepts. But the way these LLMs "learn" is very different from how human beings learn, and the same can be said for how they "reason." It's reasonable to ask, do these AI programs really understand the world they are talking about? Do they possess a common-sense picture of reality, or can they just string together words in convincing ways without any underlying understanding?

Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/08/21/247-samuel-bowles-on-economics-cooperation-and-inequality/Economics, much like thermodynamics, is a story of collective behavior arising from the interactions of many individual constituents. The big difference is that in economics, the constituents are themselves complicated human beings with their own goals and limitations. We can still make progress by positing some simple but plausible axioms governing human behavior, and proving theorems about what those axioms imply, such as the famous supply-and-demand curves. The trick is picking the right axioms that actually do apply to any given situation. Samuel Bowles is a highly regarded economist who has helped understand the emergence of political hierarchy and economic inequality, often drawing on wide-ranging ideas from game theory and evolutionary biology. We talk about how people evolved to cooperate, and why nevertheless inequality seems to be ubiquitous.Support Mindscape on Patreon.Samuel Bowles received a Ph.D. in economics from Harvard University.

You might remember the somewhat bizarre worries that swept through certain circles back in 2012, based on the end of the world being predicted by the Maya calendar. The world didn't end, which is unsurprising because the Maya hadn't predicted that, and for that matter they had no way of doing so.

Physics is in crisis, what else is new? That's what we hear in certain corners, anyway, usually pointed at "fundamental" physics of particles and fields. (Condensed matter and biophysics etc. are just fine.) In this solo podcast I ruminate on the unusual situation fundamental physics finds itself in, where we have a theoretical understanding that fits almost all the data, but which nobody believes to be the final answer. I talk about how we got here, and argue that it's not really a "crisis" in any real sense. But there are ways I think the academic community could handle the problem better, especially by making more space for respectable but minority approaches to deep puzzles.Blog post with transcript: https://www.preposterousuniverse.com/podcast/2023/07/31/245-solo-the-crisis-in-physics/Support Mindscape on Patreon: https://www.patreon.com/seanmcarrollSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Is metaphysics like physics, but cooler? Or is it a relic of an outdated, pre-empirical way of thinking about the world? Closer to the former than the latter. Rather than building specific quantitative theories about the world, metaphysics aims to get a handle on the basic logical structures that help us think about it.

Complexity scientists have been able to make an impressive amount of progress despite the fact that there is not universal agreement about what "complexity" actually is.

Today's guest, David Krakauer, is president of the Santa Fe Institute and a longtime researcher in complexity. He points the finger at the concept of agency.

It's somewhat amazing that cosmology, the study of the universe as a whole, can make any progress at all. But it has, especially so in recent decades. Partly that's because nature has been kind to us in some ways: the universe is quite a simple place on large scales and at early times. Another reason is a leap forward in the data we have collected, and in the growing use of a powerful tool: computer simulations. I talk with cosmologist Andrew Pontzen on what we know about the universe, and how simulations have helped us figure it out.

There is an image, especially in Western cultures, of the rugged, authentic, self-made individual choosing how to navigate the intricacies of the social world. But there is no mystical soul within us, manifesting as the immutable essence of self. What we think of as our "self" is shaped by our environment and our genes, and most of all by our interactions with other people. Psychologist Brian Lowery argues for a strong version of this thesis, positing that our sense of self is largely a social construct.

Modern computers are somewhat more secure against being hacked - either by an inanimate virus or a human interloper - than they used to be. But as our lives are increasingly intertwined with computers, the dangers that hacking poses are enormously greater. Why don't we just build unhackable computers? Scott Shapiro, who is a law professor and philosopher, explains why that's essentially impossible. On a philosophical level, computers rely on an essential equivalence between "data" and "code," which is vulnerable to exploitation. And on a psychological level, human beings will always be the weakest link in the chain of security.Web page with transcript: https://www.preposterousuniverse.com/podcast/2023/05/29/238-scott-shapiro-on-the-technology-and-philosophy-of-hacking/Support Mindscape on Patreon.Scott Shapiro received a J.D. from Yale Law School and a Ph.D. in philosophy from Columbia.

One of these is the offshore wealth management network, which wealthy individuals can use both legitimately (to invest and plan their money) and less legitimately (to avoid taxation or hide questionable practices generally). Brooke Harrington is a sociologist who has studied offshore wealth management, including by training to be one. In a recent paper, she and colleagues analyze networks of offshore wealth managers as a complex system, uncovering power-law behavior and interesting nation-dependent network structures.Web site with transcript: https://www.preposterousuniverse.com/podcast/2023/05/22/237-brooke-harrington-on-offshore-wealth-as-a-complex-system/Support Mindscape on Patreon.Brooke Harrington received her Ph.D. in sociology from Harvard University.

Is there a multiverse, and if so, how should we think of ourselves within it? In many modern cosmological models, the universe includes more than one realm, with possibly different laws of physics, and these realms may or may not include intelligent observers. There is a longstanding puzzle about how, in such a scenario, we should calculate what we, as presumably intelligent observers ourselves, should expect to see. Today's guest, Thomas Hertog, is a physicist and longstanding collaborator of Stephen Hawking. They worked together (often with James Hartle) to address these questions, and the work is still ongoing.Support Mindscape on Patreon.Thomas Hertog received his Ph.D. in physics from the University of Cambridge.

What is the mind, and what does it try to do? An overly simplified materialist view might be that the mind emerges from physical processes in the brain. But you can be a materialist and still recognize that there is more to the mind than just the brain: the rest of our bodies play a role, and arguably we should count physical artifacts that contribute to our memory and cognition as part of "the mind." Or so argues today's guest, philosopher/cognitive scientist Andy Clark. As to what the mind does, it tries to predict what happens next. This simple idea provides a powerful lens through which to interpret all the different things our minds do, including the idea that "perception is controlled hallucination."Support Mindscape on Patreon.Andy Clark received his Ph.D. in philosophy from the University of Sussex.

Eukaryotic cells manage to pull off a number of remarkable feats. One is packing quite a long DNA molecule, with potentially billions of base pairs, into a tiny central nucleus. A key role is played by histones, proteins that provide scaffolding for DNA to wrap around. Histones also appear in archaea (one of the other domains of life), but until recently there wasn't evidence for them in bacteria (the final of the three domains). Todays guest, Tobias Warnecke, is an author on a recent paper that claims to provide such evidence. We discuss this new result, as well as background questions of how cells evolved and what their current structure can teach us about their histories.Support Mindscape on Patreon.Tobias Warnecke received his Ph.D. in biology from the University of Bath.

Here at the Mindscape Podcast, we are firmly pro-reason. But what does that mean, fundamentally and in practice? How did humanity come into the idea of not just doing things, but doing things for reasons? In this episode we talk with cognitive scientist Hugo Mercier about these issues. He is the co-author (with Dan Sperber) of The Enigma of Reason, about how the notion of reason came to be, and more recently author of Not Born Yesterday, about who we trust and what we believe. He argues that our main shortcoming is not being insufficiently skeptical of radical claims, but of being too skeptical of claims that don't fit our views.Support Mindscape on Patreon.Hugo Mercier received a Ph.D. in cognitive sciences from the École des Hautes Études en Sciences Sociales.

If you knew exactly when every person was going to die, or require medical care, you could make a killing buying and selling insurance. Nobody knows these things, of course -- the future is hard to predict -- but some people know something about the future that other people don't. This sets up adverse selection: the ability of one party to leverage information another party doesn't have, in order to gain an economic advantage.

Human beings are small compared to the universe, but we're very important to ourselves. Humanism can be thought of as the idea that human beings are themselves the source of meaningfulness and mattering in our lives, rather than those being granted to us by some higher power. In today's episode, Sarah Bakewell discusses the origin and evolution of this dramatic idea. Humanism turns out to be a complex thing; there are religious humanists and atheistic anti-humanists.

Welcome to another episode of Sean Carroll's Mindscape. Today, we're joined by Raphaël Millière, a philosopher and cognitive scientist at Columbia University. We'll be exploring the fascinating topic of how artificial intelligence thinks and processes information. As AI becomes increasingly prevalent in our daily lives, it's important to understand the mechanisms behind its decision-making processes. What are the algorithms and models that underpin AI, and how do they differ from human thought processes? How do machines learn from data, and what are the limitations of this learning? These are just some of the questions we'll be exploring in this episode. Raphaël will be sharing insights from his work in cognitive science, and discussing the latest developments in this rapidly evolving field. So join us as we dive into the mind of artificial intelligence and explore how it thinks.[The above introduction was artificially generated by ChatGPT.]Support Mindscape on Patreon.Raphaël Millière received a DPhil in philosophy from the University of Oxford.

Every time our brain does some thinking, there are associated physical processes. In particular, electric currents and charged particles jump between neurons, creating associated electromagnetic fields. These fields can in principle be detected with proper technology, opening the possibility for reading your mind. That technology is currently primitive, but rapidly advancing, and it's not too early to start thinking about legal and ethical consequences when governments and corporations have access to your thoughts.

God is dead, as Nietzsche’s madman memorably reminded us. So what are we going to do about it? If there is no powerful force out there to guide us and give meaning to our lives, how are we supposed to live? Do we have to come up with meaning and purpose ourselves? Apparently so, and how to pull it off was a major question addressed by the existentialist movement.

Most of us strive to be good, moral people. When we are doing that striving, what is happening in our brains? Some of our moral inclinations seem pretty automatic and subconscious. Other times we have to sit down and deploy our full cognitive faculties to reason through a tricky moral dilemma.

Cities are incredibly important to modern life, and their importance is only growing. As Geoffrey West points out, the world is adding urban areas equivalent to the population of San Francisco once every four days. How those areas get designed and structured is a complicated interplay between top-down planning and the collective choices of millions of inhabitants. As the world is changing and urbanization increases, it will be crucial to imagine how cities might serve our needs even better.

Human beings have developed wondrous capacities to take in information about the world, mull it over, think about a suite of future implications, and decide on a course of action based on those deliberations. These abilities developed over evolutionary history for a variety of reasons and under a number of different pressures. But one crucially important aspect of their development is their social function. According to Michael Tomasello, we developed agency and cognition and even morality in order to better communicate and cooperate with our fellow humans. Support Mindscape on Patreon.Michael Tomasello received a Ph.D. in experimental psychology from the University of Georgia.

So you have some information — how are you going to share it with and present it to the rest of the world? There has been a long history of organizing and displaying information without putting too much thought into it, but Edward Tufte has done an enormous amount to change that.

There are few human impulses more primal than the desire for explanations. We have expectations concerning what happens, and when what we experience differs from those expectations, we want to know the reason why. There are obvious philosophy questions here: What is an explanation? Do explanations bottom out, or go forever? But there are also psychology questions: What precisely is it that we seek when we demand an explanation? What makes us satisfied with one? Tania Lombrozo is a psychologist who is also conversant with the philosophical side of things. She offers some pretty convincing explanations for why we value explanation so highly.Support Mindscape on Patreon.Tania Lombrozo received her Ph.D. in psychology from Harvard University.

Quantum gravity research is inspired by experiment — all of the experimental data that supports quantum mechanics, and supports general relativity — but it’s only inspiration, not detailed guidance. So it’s easy to “do research on quantum gravity” and get lost in a world of toy models and mathematical abstraction. Today’s guest, Andrew Strominger, is a leading researcher in string theory and quantum gravity, and one who has always kept his eyes on the prize: connecting to the real world.

One of the most powerful of all human capacities is the ability to imagine ourselves in hypothetical situations at different times. We can remember the past, but also conjure up possible futures that haven’t yet happened. This simple ability underlies our capability to organize socially and make contracts with other people.
