Welcome to another episode of The INTO THE IMPOSSIBLE Podcast! Today, host [Brian Keating](/speakers/A) sits down with neuroscientist and author [Nikolay Kukushkin](/speakers/B) for a mind-expanding journey into the nature of consciousness, intelligence, and the surprising places they might reside—even inside a humble kidney cell. Get ready to rethink everything you thought you knew about brains, memory, and what it means to truly be alive. [Nikolay Kukushkin](/speakers/B), author of *One Hand Clapping*, reveals how even the simplest organisms—from sea slugs to single cells—can display elements of learning, memory, and abstract thought. Together, these two explore not just the mysteries of the human mind, but how life sparks from non-life, the origins of language, and whether artificial intelligence could someday reach a kind of “escape velocity” of thought. You’ll hear tales from the lab, mind-bending Zen koans, wild detours into the evolution of guts (yes, guts!), and why the boundaries between humans, animals, and even machines might be more blurred than we think. Plus, what does it really mean for something to be conscious, and could you ever teach a kidney cell to remember? If you’re ready for a conversation that bridges biology, philosophy, and the deep questions at the heart of existence, don’t miss this episode. Let’s venture into the impossible together!

Nikolay Kukushkin

Cells Can Make Smart Decisions: "They will know that there's a difference between something happening on the scale of a few minutes or something happening on a scale of a few hours, that there's a difference between something that's repeated and something that's prolonged, that they can know a difference between a weak and a strong stimulus happening in this sequence versus a strong and a weak sequence happening in that order. Because of course, if it's escalating, then it's more important. And that's this. It seems like a really smart decision to make."

Nikolay Kukushkin

Is AI Conscious Like Us?: "Is that consciousness the same thing? Is what we have the same as what machines have?"

Nikolay Kukushkin

The Evolution of Consciousness: "there isn't a boundary where you suddenly transition from the outside world, from, from, from your body to your inner world, your, your brain. You get there gradually, just like we did when we talked about the sea slug."

Nikolay Kukushkin

The Birth of a New Language: "And suddenly these kids gathered together, a few hundred of them, and within months they started inventing their own language and it evolves and becomes grammatically complicated, develops nouns and verbs and adjectives. And still to this day, people speak this, this new Nicaraguan sign language."

Nikolay Kukushkin

Viral Topic: The Reality of Alien Encounters: "we tend to believe that when we encounter aliens, it's going to be lasers versus machine guns, but it's probably going to be sponges versus nuclear weapons."

Nikolay Kukushkin

Viral Topic: The Power of Slow-Motion Multitasking
"I've heard this term slow-motion multitasking. That's the best way, I think, to, to, to, to live your life. You can't multitask, you can't do many things in the exact same moment and at the same time. But what you can do is have multiple things that you're interested in. And when one becomes hard or dull or boring and there's a setback, you can refocus to something else and then refocus to the next thing."

Nikolay Kukushkin

Viral Topic: The Evolutionary Genius of Guts

"a gut is actually a pretty smart idea and it's not obvious at all."

Nikolay Kukushkin

Viral Topic: Our Minds Reconstruct Nature
Quote: "So in forming these ideas of a mammal or a bird or whatever you want to call them, we are reconstructing nature. We are reconstructing a natural pattern."

Nikolay Kukushkin

Viral Topic Title: The Evolving Role of the Brain
Quote: "What's more important is is the, the inner view on that brain is what is this decision-making process? Is that that flow from one to the other? That's what's, what's meaningful to us, that, that very flow of of information passing from one side to the other. I think that's how we need to think about our brain and and our, our mind as a whole. It's not it's not a, a thing."

🚀 Just wrapped up listening to the thought-provoking conversation between [Brian Keating](/speakers/A) and [Nikolay Kukushkin](/speakers/B) on The INTO THE IMPOSSIBLE Podcast, diving deep into one of science’s greatest mysteries: Are cells conscious? Here are my top 3 takeaways for anyone fascinated by neuroscience, AI, or the nature of consciousness: 🔬 **Cells Are Smarter Than We Think** [Brian Keating](/speakers/A) and [Nikolay Kukushkin](/speakers/B) challenge the traditional view of cells as mere biological building blocks. Even kidney cells—far removed from neurons—can *learn* and *store memories* on a molecular level, using mechanisms remarkably similar to brain cells. This reframes what it means to “remember” and could redefine how we think about intelligence in biology. 🧠 **Consciousness Is a Continuum, Not a Switch** Instead of a clear line dividing the conscious from the unconscious, [Nikolay Kukushkin](/speakers/B) argues that consciousness emerges from layers of abstract patterns—starting from the simplest reflexes in sea slugs, all the way to human self-awareness. The difference isn't categorical, but a matter of scale and complexity. 🤖 **Implications for AI: Embodiment & Memory Matter** The discussion on Large Language Models (LLMs) is especially timely. While today’s AI can mimic language, it lacks the iterative, feedback-driven memory updates found in living organisms. True artificial consciousness may require bridging this gap—and perhaps, giving machines a form of "body" to truly sense and interact with the world. The big message? The boundaries between life, intelligence, and consciousness are much blurrier—and more fascinating—than we ever imagined. If you’re interested in where neuroscience meets AI (and maybe, the universe’s best-kept secrets), I highly recommend checking out this episode and [Nikolay Kukushkin](/speakers/B)'s new book, "One Hand Clapping." #Neuroscience #AI #Consciousness #Biology #PodcastRecommendations

🧵 What if a kidney cell could help us understand consciousness? What if alien minds are closer than we think? Dive into the most mind-bending ideas on the brain, AI, and life itself, from [Nikolay Kukushkin](/speakers/B) and [Brian Keating](/speakers/A). (Thread 👇) 1️⃣ "Sea slugs are a *much more normal* animal than mice. They show us the **most minimal form of memory and abstraction**—and maybe the roots of consciousness itself." Why? Because their simplicity helps us trace *how minds emerge*, molecule by molecule, cell by cell. 2️⃣ You think only creatures with brains can "think"? [Nikolay Kukushkin](/speakers/B) is here to blow your mind: > "Cells are smarter than we think—they learn from experiences, even kidney cells!" Imagine: single cells detecting patterns, choosing what memories to keep or ignore. 3️⃣ Why do we struggle to imagine alien consciousness? Because even a sea slug is as "alien" as it gets. > "It's as hard as imagining a color you've never seen," says [Nikolay Kukushkin](/speakers/B). We *experience* the world so differently that translation may be fundamentally impossible. 4️⃣ The **Miller-Urey Experiment**: a classic that showed life's building blocks can emerge from non-life… but what happens next? We don't just ask, "What is life?" Now it's: **What is mind?** Is consciousness just a matter of scaling up cell-level memory? 5️⃣ The secret to being human? Language—specifically, *infinite* language. Unlike monkeys, apes, or whales, humans pass on complex, generative language systems that evolve over generations and expand ideas to infinity. "Language reached escape velocity," says [Nikolay Kukushkin](/speakers/B). 6️⃣ Large Language Models (LLMs) like ChatGPT: Are they alive? Are they conscious? Not yet. Why? Humans are in a feedback loop—constantly updating our models of the world in real time. LLMs are still too "separated" from their own outputs. 7️⃣ Could *real* aliens communicate with us? Probably not—unless we get lucky on the evolutionary timeline. If they landed before humans, they might've only found sponges or worms. It's not lasers vs. machine guns—it's sponges vs. nukes! 8️⃣ The gut revolution: Life went viral when animals invented the gut. That innovation turned the sea floor from a "2D mat" into a 3D feast—triggering the Cambrian Explosion and unleashing Earth's wild diversity. 9️⃣ So, what *is* the mind? It's not a thing, argues [Nikolay Kukushkin](/speakers/B): "It's a process. Our mind is nature folding back on itself, reconstructing the same patterns found in the universe." 🔟 Final thought: When you ask, "What makes us special?"—the very ability to ask that question *is* what makes us special. Our consciousness is woven from the same fabric as the stars and squiggly sea slugs. 🧠👾 If this thread has moved your mind, check out *One Hand Clapping* by [Nikolay Kukushkin](/speakers/B) and explore the physics of thinking with [Brian Keating](/speakers/A).

Drawing from his new book, *One Hand Clapping*, [Nikolay Kukushkin](/speakers/B) invites us to rethink where memory, intelligence, and even awareness begin. Here are some highlights you won’t want to miss: --- 🧠 **What Can We Learn from Sea Slugs?** Forget mice! [Nikolay Kukushkin](/speakers/B) explains why sea slugs—the "aliens" of the animal world—are actually better models for understanding the origins of memory and abstract thought than our furry lab staples. 🤔 **Do Our Cells Have Minds of Their Own?** You’ve probably never thought of your kidney cells as “smart”—but maybe you should! [Nikolay Kukushkin](/speakers/B) shares jaw-dropping research into how non-brain cells show learning-like properties, blurring the lines between neural and non-neural intelligence. 🌌 **Origins of Life, Origins of Mind** The conversation journeys from the Miller-Urey experiment (the original “life from non-life” science hack) to the evolution of the gut, showing how the building blocks for awareness might be as old as life itself. 💬 **Language: The Human Escape Velocity?** When did humans become truly human? [Nikolay Kukushkin](/speakers/B) argues it was the moment language reached “escape velocity.” But what happens when AI and LLMs like ChatGPT start to flirt with that same threshold? Can a machine have a “happy thought”? 👽 **Aliens, AI, and the Limits of Communication** Are large language models the closest thing we have to alien minds? And if we really did meet E.T., could we ever communicate—given how tightly language and evolution are entwined? 🔬 **Philosophy Meets Molecules** Part Zen koan, part cell biology, part philosophy of mind. If you’re ready to have your boundaries between self, world, and science dissolved, this is the episode for you. --- 📚 *One Hand Clapping* is a beautifully illustrated journey through consciousness. If you’re fascinated by questions like “What is an essence?” and “Can a kidney cell learn?”, it’s a must-read.

Absolutely! Here are some engaging conversation starters for a Facebook group based on the episode "Are Cells Conscious? (ft. Nikolay Kukushkin)" from The INTO THE IMPOSSIBLE Podcast: 1. **Can non-neuronal cells, like those in our kidneys, actually “learn” and form memories? What do you make of [Nikolay Kukushkin](/speakers/B)’s claim that memory isn’t just in the brain? How does this change your understanding of what it means to be conscious?** 2. **The episode compares sea slugs to “aliens” and uses them to study minimal forms of abstract thought. Do you agree that sea slugs are a better starting point than mice for understanding the mind? Why or why not?** 3. **[Nikolay Kukushkin](/speakers/B) discusses the idea that “meaning exists regardless of our imagination,” and that our minds are nature folding back on itself. How does this perspective resonate with you?

What if our brains aren’t so special? 🧠 What if the real geniuses are…our kidney cells? 👀 1/ We think of neurons as the magic behind memory and consciousness. But [Nikolay Kukushkin](/speakers/B) blows that up: all cells—not just our brain—have the tools to learn and remember. 2/ [Brian Keating](/speakers/A) asked the right question—can a kidney cell tell us anything about our minds? Turns out, yes. Every cell deals with input and output, learns from patterns, and makes “decisions” ([Nikolay Kukushkin](/speakers/B), sea slugs to kidney cells). 3/ Learning and memory aren’t reserved for creatures with big brains. Single cells detect, adjust, and even “prefer” stronger or repeated signals. That’s the root of intelligence. Not magic—just molecules. 4/ That’s why giant leaps like language didn’t appear overnight. Escape velocity was hit when feedback loops—inside brains, then societies—fed on themselves. It’s not the components, it’s the scale and recursion. 5/ Want to build real AI? Don’t copy brains. Copy *cells*. Integrate feedback. Let systems learn from their own “thoughts,” not just from a one-time training set. 6/ Our obsession with the “edge” of intelligence blinds us to what’s universal: evolution, abstraction, and learning at every level of life. 7/ That’s the lesson for founders: don’t worship the “brain.” Build products that can adapt, iterate, and self-correct—starting at their smallest building blocks. The path to mind-blowing innovation? Think like a cell. 🧬

Subject: Are Cells Conscious? Takeaways from Our Wildest Into the Impossible Yet 🌱🤯 Hey Impossible Thinkers! We just dropped a brand new episode of The INTO THE IMPOSSIBLE Podcast, and trust me, this one might actually blow your mind. Our host [Brian Keating](/speakers/A) sits down with neuroscientist and author [Nikolay Kukushkin](/speakers/B) to ask some of the deepest, weirdest questions: Can a kidney cell learn? Do sea slugs actually think? And what do aliens and advanced AI have in common with… language? Here’s what you’ll learn if you dive in: **1. Should we judge a brain by its cover—or its cells?** [Brian Keating](/speakers/A) and [Nikolay Kukushkin](/speakers/B) get right to the heart of whether consciousness and memory are truly exclusive to brains, or if our body’s unsuspecting cells could be mini-geniuses in disguise. **2. Why sea slugs might be our most honest teachers** Forget lab mice—sea slugs have way more in common with the rest of the animal kingdom (and with us!) than you’d expect. [Nikolay Kukushkin](/speakers/B) reveals how their simple nervous systems are a treasure trove for understanding abstract thought. **3. The surprising power of memory—yes, even in your kidneys** Turns out, even non-neural cells have a form of memory. Whether it’s a neuron or a kidney cell, the same fundamental processes shape what they “remember”—and what that means for our entire definition of intelligence. **4. Where language actually comes from—and what makes us human** What’s the difference between a sea slug’s signals and Shakespeare? [Nikolay Kukushkin](/speakers/B) introduces the idea of language “escape velocity”—the moment communication becomes truly infinite—and why it sets humans (and maybe future AI) apart. **5. The wild link between artificial intelligence, aliens, and life’s emergence** From the Miller–Urey “origin of life” experiments to pondering how we’d ever talk to aliens or advanced AI, this episode links deep time, evolution, and technology in one epic thought experiment. **A Fun Fact from the Episode:** Did you know the humble gut (yes—your digestive tube!) was one of the first major evolutionary inventions that “went viral”? According to [Nikolay Kukushkin](/speakers/B), the breakthrough of developing a through-gut (from mouth to, well, you-know-what) may have triggered the Cambrian explosion—ushering in the rich diversity of animal life! **Ready to unravel the mystery of minds—from the sea slug to AI?** This episode is more than just neurons and Nobel prizes—it’s about the stories our cells have to tell, and what it *really* means to be conscious. 🎧 **Listen now to The INTO THE IMPOSSIBLE Podcast, and let us know—what do YOU think your kidney is remembering?** Hit play, share with your most curious friends, and reply to this email with your biggest “Wait, what?!” moment from the show.

🎓 Lessons Learned

1 / 1

Sure! Here are 10 key lessons from the episode, each with a concise title and description: --- **1. Lessons from Sea Slugs** Sea slugs offer a minimal, clear model for studying the roots of memory and abstract thought outside the complexity of mammalian brains. **2. Animal Consciousness is Alien** We cannot truly imagine another creature’s consciousness; even mouse consciousness is fundamentally different from ours. **3. Abstract Ideas Start Simple** The formation of abstract ideas—like associating danger with touch—begins with basic neural connections, even in sea slugs. **4. Cells Possess Intelligent Memory** Single cells—including kidney cells—detect and remember complex patterns, using the same molecules as brain cells. **5. The Miller-Urey Experiment’s Legacy** Creating life’s building blocks from inorganic material in the lab proved the boundary between non-life and life could be crossed naturally. **6. Language Escapes Evolutionary Limits** Human language’s infinite capacity to generate ideas is unique—other organisms have fixed communication systems with limited messages. **7. Life’s Patterns Build Human Minds** Our minds and consciousness form through patterns evolving from nature, not from a strict human/nonhuman boundary. **8. Large Language Models Aren’t Alive** LLMs differ from humans by lacking real-time memory updates and embodied experience, but these are engineering, not philosophical, obstacles. **9. Gut Evolution Unlocked Complexity** The emergence and evolution of the gut (the “anal breakthrough”) triggered the Cambrian explosion and complex animal life. **10. All Life is Deeply Connected** Human identity and thought are patterns reflecting nature itself—our ideas are nature’s, and our minds are nature folding back on itself. ---

10 Surprising and Useful Frameworks and Takeaways

1 / 1

Absolutely! Here are ten of the most surprising and useful frameworks and takeaways from this episode of The INTO THE IMPOSSIBLE Podcast with [Nikolay Kukushkin](/speakers/B) and [Brian Keating](/speakers/A). These insights span biology, neuroscience, AI, and the philosophy of consciousness: 1. **Sea Slugs and Minimal Abstraction** Sea slugs, despite being so "alien" compared to humans, provide a powerful model for understanding the basic building blocks of thought and memory. By stripping away the complexity of the human brain, we can witness abstract ideas and behavioral responses emerge from just a few neurons. This minimalism lets us see the core mechanics of "thinking" without our usual biases. 2. **Memory as a Universal Cellular Process** [Speaker B](/speakers/B) argues that memory isn't solely a property of brains or even of neurons. In fact, individual non-neuron cells, like kidney cells, demonstrate "memory”—that is, they undergo physical and chemical changes based on patterns of experience. The same molecular machinery underlying memory in our brains also operates in other body cells. 3. **The Illusion of Fundamental Boundaries** A recurring motif from [Speaker B](/speakers/B) is that perceived hard boundaries—between self and environment, humans and animals, living and non-living—often break down the closer you examine them. The idea of "one hand clapping," borrowed from Zen, is used as a metaphor to question where these boundaries actually lie. 4. **Memory: Mechanism vs. Metaphor** They distinguish between "memory as metaphor" (any change that outlasts its cause, even in a non-biological context) and "memory as mechanism" (the actual molecular and genetic processes preserving information inside cells). This distinction is crucial for bridging biological mechanisms to broader computational or philosophical contexts. 5. **Language Evolution: Escape Velocity** Human language became unique not when language itself first arose, but when it reached "escape velocity": when our symbols, gestures, and words began self-replicating, evolving, and passing from one person to another, outpacing simple, hard-wired animal communication. 6. **Brains as Motion Controllers Turned Decision-Makers** Originally, the primary function of a nervous system was simply to coordinate movement across multicellular bodies. Over evolutionary time, this grew in complexity, eventually giving rise to decision-making, abstract thinking, and the inner life we experience as "mind." 7. **AI, LLMs, and the Consciousness Divide** A key framework for understanding why current AI systems aren’t conscious: Today's large language models (LLMs) separate learning (training) and inference. Humans, by contrast, have a continual feedback loop where every thought or perception reshapes expectations and learning in real-time. Bridging this gap is seen not as a philosophical impossibility, but an engineering challenge. 8. **Nature’s “Essences” and Patterns** [Speaker B](/speakers/B) proposes that meaning and patterns exist in nature independently of human labels or cultural interpretation. Our minds recognize and internalize these "essences," creating—and being created by—nature’s structures. 9. **Consciousness as a Matter of Scale, Not Category** The difference between basic animal awareness and full human consciousness isn’t a binary leap but a gradual scaling up—more patterns, more layers of abstraction, and more recursion enable human-level reflective consciousness. 10. **The Gut as a Revolutionary Development** The evolutionary leap of developing a through-gut (mouth and anus!) allowed ancient animals to burrow, unlocking new ecological niches. This was one of the overlooked catalysts for the Cambrian explosion, forever changing the trajectory of animal life. --- These frameworks encourage us to see consciousness, intelligence, and even memory as deeply biological phenomena that persist across scales—rather than purely human inventions. They also invite us to reflect on how much AI, language, and even seemingly "simple" cells mirror patterns in much broader swaths of life and nature.
