We don't have a way of measuring "cognitive awareness" though. We have a way of measuring electrical impulses, and how they behave in response to various treatments (eg anaesthetics or magnetic fields), but we can't objectively measure whether the system is aware at all.

We can measure electrical spikes, and we can ask the system to reply what it experiences when various spikes occur. Guess what: we can do that with ANNs now too.

It'd be one thing if this were all a philosophical discussion, but in this thread so many folks are making very firm statements about the nature of reality we have no means to back up.

The human Brain is a neural network. Your sense of “knowing what warmth is” reduces down to the weights of connections between neurons in an analog of LLMs. What is different about the human brain that warrants saying that the same emergent characteristics for one network are inaccessible to another?

I’m not sure I fully understand the distinction you’re making, or if I do I’m not sure I agree. Concretely, I agree that these are very different mechanisms. Abstractly… I agree that an LLM cannot be burned. I’m not sure I agree, though, that there is a significant conceptual difference between thermoreceptors in the skin causing action potentials to make their way up the spinal cord to the brain is all that different than reading a temperature sensor over I2C and turning it into input tokens.

Edit: what they don’t have, obviously, is a hard-coded twitch response, where the brain itself is largely bypassed and muscles react to massive temperature differentials independently of conscious thought. But I don’t think that defines consciousness either. Ants instinctively run away from flames too.
