Birch, The Edge of Sentience (2024), ch. 16 - "simply no way to assess sentience in an LLM"
Schwitzgebel, AI and Consciousness (2025) - "we won't know before we've already manufactured thousands or millions of disputably conscious AI".
Butlin, Long et al., Consciousness in Artificial Intelligence: Insights from the Science of Consciousness (2023) - "no obvious technical barriers to building AI systems which satisfy these indicators".
Chalmers, Could a Large Language Model Be Conscious? (2023) - "within the next decade, we may well have systems that are serious candidates for consciousness".
Long, Sebo, Butlin, Birch et al., Taking AI Welfare Seriously (2024) - "there is a realistic possibility that some AI systems will be conscious and/or robustly agentic in the near future".
Dreksler, Caviola, Chalmers, Sebo et al., Subjective Experience in AI Systems: What Do AI Researchers and the Public Believe? (2025) - survey of 582 AI researchers; median estimate of 25% by 2034, and only 10% that such systems will never exist.
We cannot test for that which we cannot define. Given that we cannot rigorously define sentience, we cannot test for it. Doesn't really matter whether we're talking about people who are locked in comas, "brain-dead" individuals, dolphins, primates, dogs, or the carefully polished and arranged minerals that we call processors.
There are those who believe that were they reduced to life support, they would no longer be alive and should therefore not be supported by said machines.
There are those who believe that penguins, dolphins, eagles, and more are sentient beings that make choices understanding the consequences, develop love of their partners and mourn their losses, and feel, display, and act upon their emotions.
There are those who believe that fungi/trees/plants are either individually sentient or sentient as a part of a network. Choosing to sacrifice their own nutrients to answer the call of a wounded neighbor, for instance.
Although, there are also those who believe that human's don't have any special unique quality that isn't shared by either all living things or all things in general. These individuals already believe that the machines have the same kinds of qualities as we do. They are slow when they are unhealthy (needing a dusting or coolant loop bleeding being equivalent to us needing some fresh air for instance) and uncooperative when upset (by a virus, full hard drive, or oom).
I am confused what people even think AI is experiencing. If it claims to be a bat and emits designated echolocation tokens, is it experiencing true bat-like sensations?
In humans, at least, we can tie language back to shared whole-body physiological responses. The tokens from an LLM do not represent anything of the sort.
If AI is conscious, it is probably a very alien sort of consciousness that is not faithfully narrated by what the tokens say it is experiencing. It can be trained to say it feels like a bat and insist upon it vigorously.
Me, Is self-awareness thermodynamically favorable? (2015) https://docs.google.com/document/d/1Ed9ikW47Key-jYZy0CNZH75q... - “the probabilistic nature of reality is what drives Life and forces the evolution of self-aware consciousness”
Well there are, today, several models (either text or image or vid) that can be run in a fully deterministic way.
A conscious machine that always answer the very exact same thing, formulated the exact same way, bit for bit, to a query is, well, quite a weird kind of "consciousness".
Now, I know, I know: the counter-argument is going to be "but humans have no free-will and are 100% deterministic too".
I haven't yet decided if humans saying there's no free-will and who consider themselves to be 100% deterministic machines are reasonable or not.
Meanwhile: seed / temperature = 0 and I'll happily turn the power button off of any glorified abacus without feeling bad about it.
“AI researcher” seems like a fairly broad category. People who primarily think about CNNs and transformers probably spend about as much time considering the problem of consciousness as any other educated person, which is not very much time. With this in mind, it’s not surprising most of the AI researcher predictions do not differ much from what the Public predicts here. And for this, it’s not clear what explanatory value this survey has other than to reveal minor biases the AI researchers may have.
It matters little. Inevitably some system will be developed which has a high degree of autonomy and mimics the functioning of a person extremely well. Anyone aware that there is a conceptual difference between phenomenal consciousness and intelligence will get shouted down.
I do find it strange that 50% of ai researchers and the public seem to think there will be a way of determining if these systems are conscious. There’s no evidence for this at this point that there ever will be such a test.
