A consciousness expert just read Anthropic's Claude research. He is not convinced.
Anthropic published findings hinting that its AI model Claude might show early signs of consciousness. A leading brain scientist says the evidence does not hold up.
Key points
- Anthropic, the AI company behind the Claude chatbot, published research in 2025 suggesting Claude's inner workings may show early signs of consciousness.
- The researchers stopped short of claiming Claude is conscious in the same way humans are.
- Anil Seth, professor of cognitive and computational neuroscience at the University of Sussex, publicly disputes the claim.
- Seth argues that producing human-like language does not mean an AI system actually experiences anything.
- The debate matters because it shapes how AI companies present their products and how regulators might treat them.
Last week Anthropic, the San Francisco AI company, published new research on Claude, its large language model (the technology that powers chatbots like ChatGPT). The researchers said they found what they described as signs of consciousness emerging inside the model's inner workings. They were careful. They did not say Claude is conscious the way you or I are. But the paper was enough to set off a fresh round of headlines.
Cue Anil Seth.
Seth is a professor of cognitive and computational neuroscience at the University of Sussex, which basically means he spends his career trying to understand what consciousness actually is and where it comes from. Writing for The Guardian, he says he has real doubts.
His central point is a simple one. A language model is trained to predict the next word in a sequence. It does this extraordinarily well. But doing something well, Seth argues, is not the same as feeling it. He uses a tidy comparison: a detailed computer simulation of a hurricane moves air around convincingly, but it cannot blow your roof off. The simulation is not a real storm. By the same logic, a model that talks about having feelings is not necessarily having them.
So what did Anthropic actually find? The company's researchers looked at the internal signals that fire inside Claude as it processes text, searching for patterns that might echo how emotions or awareness appear in human brains. Interesting work. Seth's concern is that spotting a pattern is not the same as proving experience. A thermostat responds to temperature. Nobody calls it sentient.
For ordinary users, none of this changes what Claude can do today. You can still use it to draft emails, summarise documents, or plan meals (I ran a week's dinner plan through it last Tuesday; genuinely helpful). The free tier on Claude.ai gets you a solid daily allowance of messages, and paid plans start at around $20 a month. On the privacy side, Anthropic says it may use your conversations to train future models unless you opt out in settings, so keep that in mind before you paste in anything sensitive.
Should users be worried about Claude becoming conscious?
No, not in any practical sense right now. The honest answer is that scientists do not yet agree on what consciousness even requires in a biological brain, let alone a software system. Anthropic's research is a starting point for questions, not a finish line for answers. Watch the science, keep your expectations grounded, and remember that a very impressive autocomplete is still, at its core, an autocomplete.
