Can AI Become Conscious?
Key points
- As of 2026 the only consensus is narrow: no AI has been confirmed conscious — but consciousness cannot be ruled out either
- Skeptics hold that consciousness depends on a biological substrate; however well an algorithm performs, performance is not experience
- The middle camp is agnostic: without an agreed theory of consciousness there is no reliable test
- The affirmative camp holds that with the right computational structure, consciousness could arise in machines, and its probability is underestimated
- A 2025 adversarial experiment in Nature challenged both leading theories — IIT and Global Workspace Theory — at the same time
The core dispute
When a large language model talks fluently about feelings, expresses 'preferences' and even reports 'inner states', an old question reignites: does it really have subjective experience, or is it only imitating the language of experience with extreme fidelity? This is not wordplay — if AI might be conscious, whether it deserves moral consideration, and whether switching it off could be a harm, become practical questions.
The case that it could be conscious
Computational functionalism holds that consciousness depends on how information is organized, not on the material: if a system implements the right computational structure, silicon and carbon are not fundamentally different. In 2023, 19 researchers including Bengio and Chalmers assessed mainstream AI against indicators drawn from neuroscience theories and concluded that current systems do not yet qualify — but that there is 'no obvious barrier' to future systems qualifying. Other researchers argue, in Bayesian terms, that the probability of consciousness in frontier models has been systematically underestimated.
The skeptical case
Skeptics argue consciousness cannot be separated from biology: metabolism, a body and an evolutionary history are the substrate of experience, and an algorithm running on GPUs simulates it at best — just as a simulated rainstorm wets nothing. Neuroscientists such as Anil Seth publicly maintain that today's AI lacks the biological infrastructure for phenomenal experience. In 2026, Tononi and colleagues published three reasons in Nature for thinking current AI is not conscious and is unlikely to become so along the present path.
Why there is still no answer
The root difficulty: science has no agreed theory of human consciousness either. Integrated Information Theory (IIT) and Global Neuronal Workspace Theory (GNW) are the two leading frameworks and they deliver different verdicts; the Cogitate consortium's preregistered adversarial experiment, published in Nature in 2025, challenged both at once. With no accepted theory there is no accepted 'consciousness detector' — we can neither prove an AI is conscious nor prove it is not. Cambridge philosopher McClelland therefore argues agnosticism is the only defensible position for now.
Where things stand
Companies such as Anthropic have set up 'model welfare' research programmes while acknowledging there is no scientific consensus, and major labs publicly state that current systems have not been shown to be conscious. The only common ground across all three camps: the question deserves serious study, and any confident answer goes beyond the evidence.
