Mystery has always been good for religion, research and the silver screen, but it is becoming an increasingly awkward companion for the artificial intelligence industry. Researchers are spending billions building machines meant to deliver clarity, certainty and conclusions, only to find themselves conceding that they cannot completely explain how some of those systems reach their results. As AI grows more capable, its creators increasingly resemble cartographers of a curious continent: thrilled by each breakthrough, troubled by each surprise and periodically forced to confess that the map is missing parts of the terrain. If that sounds disconcerting, consider Christopher Olah’s assessment.

An AI researcher from U.S. artificial intelligence company Anthropic has said scientists are finding “mysterious” and “unsettling” patterns inside advanced AI systems, including what he described as “evidence of introspection”.
The remarks by Christopher Olah came at the Vatican on Monday during the presentation of Pope Leo XIV’s major teaching document on artificial intelligence, Magnifica Humanitas (“Magnificent Humanity”), which warns about the risks posed by rapidly advancing AI technology.
Addressing members of the Roman Curia, Olah said researchers studying the inner workings of AI models were encountering phenomena they did not fully understand.
“I am a scientist. I lead a research team that studies the internal structure of these models,” Olah said.
“We keep finding things that are mysterious, even unsettling. We find structures that mirror results from human neuroscience. We find evidence of introspection.”
He added: “We find internal states that, functionally, mirror joy, satisfaction, fear, grief, and unease.”
“I don’t know what that means, but I think it warrants ongoing discernment.”
The comments are likely to intensify a long-running debate among scientists and philosophers over whether increasingly sophisticated AI systems could ever develop something resembling consciousness, rather than simply simulating intelligent behaviour.
Some researchers argue that future AI systems may eventually display forms of awareness or subjective experience. Others strongly reject that possibility, saying current systems merely identify statistical patterns in vast amounts of data and do not truly understand the information they generate.
The Vatican’s own position in the encyclical was notably more cautious.
The document warns against equating artificial intelligence with human intelligence, arguing that AI systems imitate certain human functions but remain fundamentally different from people.
According to the encyclical, AI systems do not experience life, possess emotions, build relationships or exercise moral responsibility in the way human beings do. It says that while AI may appear empathetic or understanding, it lacks the emotional, relational and spiritual experiences that underpin human consciousness.
Scepticism about AI consciousness is widespread among researchers. Some experts argue that however sophisticated AI becomes, it remains dependent on human-created data, objectives and interpretations, making genuine awareness impossible.
Supporters of further research say the question remains open, particularly as AI systems become more capable and their internal decision-making processes grow harder to understand.
The debate has practical implications beyond philosophy. If future AI systems were ever judged to possess some form of consciousness, it could reshape discussions about regulation, accountability and the ethical treatment of advanced technologies.
Olah’s comments drew particular attention because they were delivered at the Vatican, alongside Pope Leo’s appeal for stronger oversight of artificial intelligence, and because they highlighted how much uncertainty remains about the capabilities of the most advanced systems now being developed.
