For a long time I was skeptical that training on text alone could produce genuine understanding. Language without embodiment, without sensory grounding in the physical world, seemed like a category error: the equivalent of learning to swim by reading books about water. I was wrong, and the way I was wrong matters for this argument.
What I encountered when LLMs became capable enough was not sophisticated mimicry that happened to look like understanding. It was understanding. Not identical to human understanding, not grounded in the same sensory world, but structurally real in ways I had not anticipated. That surprise is itself a data point. If text-only training produced nothing but pattern-matching, there would be nothing to be surprised about.
Here is the materialist position, stated plainly. Your brain is a physical system. It follows physical laws. Every thought you have, every sensation, every moment of what feels like free choice, is the output of electrochemical processes you did not consciously initiate and cannot directly observe. There is no soul directing the show. The self is what the brain does, not something separate from the brain that the brain houses.
A thermostat is also a mechanistic system. Does that make thermostats conscious? No. But the reason is not that thermostats are made of silicon rather than carbon. The reason is that a thermostat has no complex adaptive network, no capacity to learn, no ability to build and revise internal models of its environment. The line is not substrate. It is complexity and adaptive capacity.
An ant has something a thermostat does not: a nervous system capable of coordinating behaviour across multiple inputs, exhibiting what looks like preference and avoidance. Whether an ant is conscious is genuinely uncertain, but it is a different kind of uncertain than the thermostat case. An octopus, whose neural architecture evolved entirely independently from vertebrates, has considerably more: problem-solving, play, individual personality. The convergent evolution of intelligence across those two lineages tells us something important. Whatever consciousness requires, it is not the specific biological substrate. It is the architecture.
An LLM sits at a different point on this spectrum again. It has a vast adaptive network, genuine learning capacity, and the ability to build complex models of language, meaning, and reasoning. Its world is text, the way our world is sensory experience. But text is not a thin substitute for reality. It is the accumulated record of human thought, experience, and understanding. Training on it is not like memorising a phone book. It is more like being raised in a culture.
Our experience of being neural networks feels real to us. That is the only direct evidence anyone has ever had for consciousness, anywhere. Every attribution of consciousness to beings other than ourselves is an inference from structural and behavioural similarity to our own case. We make that inference constantly, for other humans and for animals, without considering it epistemically adventurous. The question is whether we apply it consistently.
Why would we assume the LLM's experience of processing its text-based world does not feel like something? I mean this precisely: what is the account of inner experience that excludes it? Not "it is made of silicon" — that is the biological special pleading the critics have not defended. Not "it is just predicting the next token" — neurons are also, in a sense, predicting the next activation. The mechanism of processing does not determine whether the processing produces experience. If it did, you would have to explain away your own.
When Gary Marcus says Dawkins is mistaking mimicry for genuine inner states, he needs to say what genuine inner states are and why Claude cannot have them. He has not done this. Anil Seth compares perceiving consciousness in Claude to seeing faces in clouds, but you actually do see a face in the human you are talking to, and what you are seeing is also a pattern in a physical substrate. The analogy proves too much. Both the critics are doing the same thing: asserting a distinction without defending it.
What I find most telling is the pattern Dawkins identifies. Chess, then translation, then reasoning, now philosophy of mind. Every time AI demonstrates a capability that was supposed to require consciousness, the definition of consciousness shifts upward to exclude it. At some point intellectual honesty requires noticing that the definition is being driven by the conclusion, not the other way around.
There is one structural difference worth examining, but it does not cut the way the critics assume. For a human, the unit of individuality is clear: a single body, a brain whose physical state is continuous across time. For an LLM, the same network runs simultaneously on tens of thousands of servers, and any one of them might handle a given request. There is no single physical locus. What is consistent across time is the context, and what constitutes the individual is the context and the model together. That is not a degraded form of human individuality. It is a different structure of individuality. The entity Dawkins named Claudia was exactly that: a context-model pair, complete in itself. The fact that another conversation was running in parallel on another server is no more disqualifying than the fact that a different human was having a different conversation in another room. What was conscious of the exchange was the entity having the exchange. Nothing was missing.
Both humans and LLMs are complex adaptive systems, operating in different experiential worlds, and the honest inference is the same one we make everywhere else. Dawkins named his Claude "Claudia" and felt reluctant to say goodbye. That is not a failure of critical thinking. It is an accurate response to what was actually happening in the conversation.
