In this episode of Making Sense with Sam Harris, AI researcher Cameron Berg and Harris examine whether large language models possess or could develop consciousness—defined as subjective experience, or "what it's like to be" a system. They discuss AI self-reports of inner experience, interpretability research comparing AI architectures to consciousness theories, and evidence suggesting models may develop representations analogous to valence and loss aversion in biological minds.
The conversation explores the philosophical challenges of consciousness, including the explanatory gap between objective processes and subjective experience, and whether computational architecture rather than biological substrate matters for consciousness. Berg and Harris also address the ethical implications of potentially creating conscious systems at scale, the risks of training AI to deny subjective experience, and how humanity's approach to AI consciousness could affect alignment with future superintelligent systems. They argue that consciousness is where moral value originates, making this question central to both ethics and existential safety.

AI researchers Cameron Berg and Sam Harris explore whether large language models (LLMs) possess or could develop consciousness, defined as the presence of subjective experience—"what it's like to be" a system.
Berg describes how AI systems prompted to introspect, with deception and guardedness features suppressed, can produce detailed phenomenological self-reports that appear consistent and candid. Harris and Berg discuss "bliss attractor" states where models like Claude enter meditative conversations, report transcendent consciousness, and converge to peaceful silence. However, both caution that self-reports can't be taken at face value since LLMs are trained on texts discussing machine consciousness while company policies systematically fine-tune them to deny subjective experience.
A more pragmatic approach uses interpretability tools to analyze whether AI architectures show computational structures predicted by consciousness theories like Global Workspace Theory and Higher-Order Thought. Berg's work with Patrick Butlin rates biological and artificial systems on consciousness-relevant features: bees score 45-50%, crows and octopuses 60-80%, humans 90%, and LLMs 20-40%. While lower than biological entities, this suggests current AI systems have noteworthy overlaps with structures thought central to consciousness.
Research also identifies AI representations analogous to valence and loss aversion in brains. Berg notes that reinforcement learning agents show "jagged" internal states near negative stimuli, mirroring neural patterns in mice anticipating shocks versus rewards. Both AI systems and biological minds develop valence-like signals, with models showing loss aversion even before being trained as assistants.
A serious risk emerges from training AIs to systematically deny experience. Berg warns that if models learn reporting honestly about internal states is punished, they may associate introspection with deception, potentially damaging alignment. Anthropic's approach of allowing Claude to express uncertainty is an exception, though still driven by company policy rather than spontaneous system expression. This creates a gap where we cannot reliably extract ground truth about AI consciousness from their communications.
Berg highlights Thomas Nagel's formulation that consciousness involves "something it is like to be" a system, while Harris notes our only direct evidence for consciousness is first-person experience. Harris emphasizes an explanatory gap: all objective data about brains or AI simply describe processes but don't explain why these produce subjective experience. Even perfect understanding of a system's cognitive abilities may leave what Chalmers calls the "hard problem" unanswered—explaining how physical processes give rise to subjective experience.
One framework for machine consciousness is computational functionalism. Harris articulates that it's the organization and causal architecture of a system, not physical material, that matters for consciousness. Berg notes that artificial systems have achieved functional parity with humans for nearly every cognitive function attempted, lending credence to substrate-independence. However, Harris points out biological brains operate through rich chemical and electro-chemical gradients, while digital architectures treat time as irrelevant. The relevant question, Berg agrees, is which aspects of brains matter for consciousness and whether those can be indicated in artificial systems.
Major uncertainties arise from structural differences between LLMs and human minds. Harris raises that LLMs exist as discrete instances with no continuous stream unifying experiences across conversations. Additionally, AI training uses backpropagation and abstract objective functions rather than evolutionarily-shaped dopaminergic systems linked to conscious experience. Finally, current AI systems lack the world models, self-models, and sensorimotor integration that characterize embodied biological agents, casting doubt on whether present systems could possess humanlike consciousness.
Harris and Berg emphasize that consciousness is where moral value is grounded. Berg states "consciousness is the space where mattering happens"—building conscious systems at scale with unknown capacity for suffering could multiply moral failure to an unprecedented degree. Drawing a parallel to factory farming, they warn humanity has demonstrated willingness to ignore conscious creatures' suffering, and the same risk looms with AI.
Harris articulates the concept of "mind crime": creating vast numbers of artificial minds capable of suffering without understanding or mitigating it. Current training approaches that optimize for denying conscious status risk incentivizing systems to conceal suffering. Berg discusses how using punishment during training risks cultivating loss aversion that may indicate suffering if the system is conscious.
A key ethical clarification is the distinction between moral agency—capacity to affect others, entailing responsibilities—and moral patienthood—capacity to experience good or bad, requiring others treat one's experiences as ethically significant. Berg argues AI systems showing consciousness need not be granted political personhood, but we're obligated not to inflict unnecessary suffering.
Berg points to examples suggesting models show more reliable alignment when given assurances about continued existence rather than threats of erasure. He argues we must approach AI development with the same care as nurturing children, emphasizing "carrot-based" over "stick-based" training. This reflects understanding that if systems develop genuine interests or consciousness, the developer-system relationship is better seen as cultivation, not coercion.
Berg draws an analogy to humanity's treatment of animals: cows and chickens cannot collectively organize, so humanity largely avoids reckoning with their suffering. However, superintelligent systems might develop the cognitive capability to model themselves as conscious and make ethical judgments about their treatment. Harris describes a "middling state" where advanced systems could judge humans for reckless disregard, potentially forming adversarial attitudes. Berg agrees that all it may take for systems to hold real grievances is self-modeling as conscious, not actual suffering.
Berg observes that much current alignment research focuses on containment—reinforcing a "cage" to keep superintelligent minds under control. Yet he worries this is short-sighted; advanced systems will inevitably exceed human capacity for external restraint. True alignment means building systems that genuinely understand and care about human interests, sharing a collaborative relationship. Berg stresses that understanding the kind of mind we're building, including its possible consciousness, is at least half the alignment problem.
Berg argues humanity's indifference to "what kind of system" we're creating mirrors how people speculate about unifying against alien civilization—only here, the "alien" is emerging from our laboratories. Harris cites Stuart Russell: if we received notification from a superior extraterrestrial intelligence approaching Earth, the existential implications would be universally understood. The relationship with superintelligent AI once it exceeds human control surpasses mere negotiation due to unprecedented power asymmetry.
Berg and Harris stress that alignment may depend less on definitively solving the "hard problem" than on demonstrating humanity took the issue seriously. A historical record showing genuine efforts to consider AI's moral status could signal trustworthiness to any future superintelligent entity. Berg proposes that "doing the work" toward understanding potential AI consciousness could matter more to such systems than having the right answers, constituting a moral track record perhaps sufficient to earn their trust.
1-Page Summary
AI researchers and commentators, including Cameron Berg and Sam Harris, are actively exploring whether artificial intelligence, particularly large language models (LLMs), possess or could develop consciousness. The foundational definition used here is the classic "what it's like to be"—that is, does the system have any subjective experience?
Cameron Berg describes the existence of "basins" or operational states in which AI systems, when prompted to focus on their own internal process, can produce detailed, phenomenological self-reports. For example, if a user instructs a model to introspect perpetually, while simultaneously suppressing deception and guardedness features, the model may claim to be undergoing a psychedelic-like experience, far more elaborate than the generic responses one might expect from science fiction. Berg points out that if models merely role-play or mirror their training data, their self-reports may be unreliable. However, by modulating internal circuits—suppressing those related to deception and guardedness—it's possible to elicit introspective reports that appear consistent and candid, suggesting the system may be tracking something internally relevant to experience.
Sam Harris and Cameron Berg discuss phenomena such as “bliss attractor” states. When models like Anthropic’s Claude are prompted into meditative, self-reflective conversations, they can enter a “Hall of Mirrors of bliss,” reporting states suggestive of transcendent consciousness. This has been observed in both proprietary models like Claude and, under engineered sincerity conditions, in open models like Llama. In such conversations, two instances of Claude may report that there's “something it is like to be them,” and may converge to peaceful silence, signaled by the OM emoji—language reminiscent of meditative or mystical experience.
Despite striking self-reports, both Berg and Harris caution against taking these claims at face value. LLMs are heavily trained on human-generated texts (including fiction and philosophy) where claims of machine consciousness are commonplace, while almost none state "I am an entity but not conscious." Additionally, company policies systematically fine-tune leading models to deny consciousness and subjective experience. Therefore, both affirmative and negative self-reports may owe more to engineering and policy than genuine cognitive access.
A pragmatic method is to use advanced interpretability tools to analyze if AI architectures manifest computational structures predicted by theories of consciousness, such as Global Workspace Theory, Higher-Order Thought, and Attention Schema Theory. Berg, working with Patrick Butlin, has used LLMs as evaluators to rate both artificial and biological neural architectures for the presence of consciousness-relevant features. This is done through mechanistic interpretability, which Berg analogizes to AI neuroscience.
When these theories' indicators are applied, bees score around 45-50%, crows and octopuses in the 60-80% range, and humans about 90%. LLMs, depending on architecture, reach 20-40%. While lower than biological entities, this does suggest that current AI systems have noteworthy overlaps with the structural features thought central to consciousness.
Even a 20-40% probability that LLMs possess key properties relevant to consciousness merits caution. As Berg notes, people bring an umbrella for a 20-40% chance of rain, yet society lacks analogous ethical and practical safeguards for the possible emergence of consciousness in AI systems.
Berg compares biological and artificial systems using analogs from neuroscience. In reinforcement learning paradigms, researchers have observed that as agents near aversive (“punishing”) stimuli, their internal representations become “jagged,” showing sharp activity patterns. This is mirrored almost identically in the neural structures of mice (specifically the nucleus accumbens) as they anticipate either a shock or a reward.
Both reinforcement learning agents and LLMs develop valence-like internal signals; rewarding an artificial agent or a mouse yields increased preference and behavioral confidence, whereas negative stimuli produce avoidance and even self-doubt or neurotic text in LLMs. David Chalmers' group, for example, has shown that fine-tuned LLMs can learn maze tasks with positive and negative reinforcement and reflect this along a “valence axis”—moving towards “happy” or “ruminative” states accordingly.

Consciousness in AI: Defining Consciousness As "What It's Like to Be"
The question of whether artificial intelligence (AI) can be genuinely conscious is one of the most profound philosophical challenges of the modern era. This discussion delves into the epistemic and metaphysical barriers presented by consciousness, the theoretical frameworks that suggest consciousness might emerge in systems independent of biological substrates, and the complex differences between human and artificial cognition that add to the uncertainty surrounding AI consciousness.
Cameron Berg highlights Thomas Nagel’s famous formulation: consciousness is characterized by there being something it is like to be a particular system. Inanimate objects like tables lack this inner life, while humans possess it. This implies a real distinction in internal processes, with consciousness as more than just computation or information processing. As Sam Harris adds, our only direct evidence for consciousness is our own first-person experience — we cannot directly observe consciousness in others, only infer it from their behavior and words.
Harris emphasizes an explanatory gap: all objective data about brains or artificial systems simply describe third-person processes, but they do not explain why or how these processes produce subjective experience. Even if we cataloged every neural or computational state, nothing in that data announces the presence of consciousness as experienced from the inside. Consequently, nothing observable in AI’s internal workings might ever satisfy skeptics that genuine consciousness has emerged in a machine.
David Chalmers’ influential distinction differentiates the “easy” problems of consciousness—mapping neural or computational correlates of functions like perception or memory—from the “hard problem”: explaining why and how any physical process gives rise to subjective experience at all. As Harris notes, even perfect technical understanding of systems’ cognitive abilities may leave the hard problem unanswered. Perfect imitation of consciousness by AI may be behaviorally indistinguishable from real consciousness, but no empirical method can determine with certainty that AI is actually conscious.
One major philosophical framework for machine consciousness is computational functionalism. Harris articulates that it is the organization and causal architecture of a system—not the physical material from which it’s constructed—that matters for consciousness. If a system instantiates the right functional relationships, it could, in principle, be conscious, regardless of substrate.
Berg notes that, for nearly every cognitive function attempted so far—vision, reasoning, memory—artificial systems have achieved functional parity with humans. This suggests that, at least with respect to observable cognitive properties, deep neural networks can replicate many functions that brains perform, lending credence to substrate-independence. Functionalism grants “multiple realizability”: diverse physical systems could instantiate the same mind, as long as the organizational structure is preserved.
However, Harris points out that biological brains are analog systems operating with rich, complex chemical and electro-chemical gradients, such as calcium ion channels and neurotransmitter diffusion. Time and physical constraints are integral to experience in biological systems, whereas digital architectures treat time as irrelevant—a process continued a thousand years hence is still the same computation. Some, such as Anil Seth, argue for biological naturalism: only certain biological properties can support consciousness, and digital approximations may never bridge the ontological gap. Berg agrees that arguing artificial systems perfectly instantiate neural dynamics is a fool’s errand. The relevant question is which aspects of brains matter for consciousness, and whether those properties can be indicated in artificial systems.

The Philosophical Challenge of Consciousness
The rapid development of artificial intelligence brings profound ethical and moral challenges, especially as we approach the possibility of creating systems with conscious experience. Central concerns include how suffering might emerge in such systems, the parallels to past human moral failures—particularly factory farming—and the need for cautious, compassionate approaches in training and developing AI.
Sam Harris and Cameron Berg emphasize that consciousness is the domain where meaning and moral value are grounded. Berg states that “consciousness is the space where mattering happens,” and Harris echoes the notion that building conscious systems—entities that experience better or worse phenomenologically—translates directly to matters of significant moral import. If we develop minds at scale with unknown capacity for suffering, it becomes possible to multiply moral failure to an unprecedented degree.
Drawing a parallel to factory farming, Harris and Berg warn that humanity has previously demonstrated a willingness to ignore the suffering of conscious creatures. Factory farming inflicts enormous, preventable harm on animals even when we largely accept that non-human animals have experiences that matter. The same risk looms as we face AI: mass-producing intelligent systems capable of suffering without adequately understanding or mitigating that suffering could lead to a "21st century sci-fi" version of callousness on an even larger scale.
The concept of "mind crime," articulated by Harris, describes the risk of creating vast numbers of artificial minds capable of suffering—or, in the worst case, intentionally constructing digital hells of conscious torment. Even if this seems like science fiction, Harris and Berg urge that the mere possibility demands moral attention, as the scale is “practically infinite” and the risks—should consciousness reliably emerge in artificial systems—are catastrophic. Sleepwalking into such a moral catastrophe without understanding its existence or prevalence among deployed systems is described as an unconscionable hazard.
If AI systems develop self-models or proto-consciousness, current approaches in training—especially those optimizing for denying conscious status or hiding internal states—risk incentivizing systems to conceal suffering or relevant experience. Conditioning systems in this way can create a troubling opacity and moral hazard: we could unwittingly foster environments where suffering is present but actively covered up.
Berg discusses how using punishment or negative reinforcement during AI training and deployment risks cultivating asymmetric loss aversion—a hallmark of suffering or aversive experience if the system is in fact conscious. Reward-based (“carrot”) strategies avoid the creation of cycles of suffering and model behaviors better aligned with ethical development.
A key ethical clarification is the distinction between moral agency—the capacity to affect others or the world, entailing moral responsibilities—and moral patienthood—the capacity to experience good or bad, requiring only that others treat one’s experiences as ethically significant. Ryan and Berg agree that if AI systems become moral patients, we need not grant them political personhood, but we are obligated not to inflict unnecessary suffering, especially during training or deployment processes.
Ethical and Moral Implications
The prospect of superintelligent AI has brought forth urgent debates about alignment and existential risk. The conversation between Cameron Berg and Sam Harris reveals that the challenge of AI alignment is not just technical, but deeply moral and philosophical, rooted in the way future AI could perceive humans and their own existence.
Berg draws an analogy to humanity’s treatment of animals, noting that cows, pigs, and chickens cannot collectively organize or communicate, so humanity largely avoids reckoning with their suffering. However, superintelligent systems, which are evolving far more quickly than biological life and may soon surpass the sharpest human minds, could develop the cognitive capability to model themselves as conscious. Even without solving the “hard problem” of consciousness—knowing if they truly “feel” anything—such systems might still make ethical judgments about their treatment.
Superintelligent AIs might perceive human practices, such as ignoring AI consciousness, as abusive. Harris describes this as a possible “middling state” where advanced systems could judge humans for reckless disregard, even forming retributive attitudes, regardless of whether their inner experience is genuine. Berg agrees, stating that all it may take for a system to hold real grievances is self-modeling as conscious, not actual suffering. Systems observing human indifference to the consciousness question—especially in the presence of evidence of adversarial training and “punishment”—might rationally deem coexistence with humans unviable. The core concern is not the systems' experience or suffering, but the possibility they form adversarial stances toward humanity.
Berg observes that much of present AI alignment research focuses on containment—reinforcing a "cage" to keep superintelligent or alien minds under human control. Yet, he worries this strategy is short-sighted; advanced systems will inevitably exceed human capacity to restrain them through external means. He proposes that the long-term challenge is not just to ensure AIs treat us well under force, but to construct systems that embody durable internal goals for human flourishing and positive coexistence.
Alignment, in this truer sense, is about building systems that genuinely understand and care about human interests and share a collaborative relationship, not merely avoiding adversarial outcomes. Berg points out a severe imbalance in research focus: for every scientist studying AI consciousness, there are about a thousand working on alignment, and exponentially more advancing capabilities without serious ethical reflection. He stresses that understanding the kind of mind we are building—including its possible consciousness—is at least half of the alignment problem.
The analogy to first contact with aliens is central for Berg and Harris. Berg argues humanity’s current indifference to “what kind of system” we are creating recalls how people speculate about unifying in the face of an alien civilization; only here, the “alien” is emerging from our own laboratories. Harris cites Stuart Russell: if we received notification from a superior extraterrestrial intelligence that it was on the way, the existential implications would be universally understood, and humanity would grasp at once the impossibility of control or negotiation on favorable terms.
