Acting on an internal state?
Aware you have an internal state and can adjust it internally? Why cant some code do that?
But no, consciousness is not just "acting on an internal state". A toaster acts on an internal state. It is a complex phenomenon in which an internal state, and the environment interact to create an internal state and a subjective experience of that state which is felt by the organism.
This will go down a rabbit hole, and I don't want to engage in a discussion about what consciousness and feelings are, but there is not reason to believe that computers have feelings. And the output of computer language models is not good evidence that they have feelings, particularly those which are trained on the language models of creatures which have feelings (humans). If they were trained on the language of birds, we wouldn't say there's evidence they are afraid of dogs, even if they were to engage in loud chirping when presented with a dog.
