I am far from convinced that the training and inference regimes of LLMs would qualify as “experience” by any sense of the word.
Now, if we hooked up a plethora of audiovisual and tactile sensors with live feedback directly to a neural network rich with transformers, that was always powered on and fully autonomous, we may be getting there. But we’d probably also be on the verge of manmade horrors beyond our comprehension.
Biological rodent neural networks in a Petri dish stimulated by electrical impulses - more or less conscious than LLMs?
Human on life support, unable to respond to any external stimuli, “braindead” - more or less conscious than LLMs?
And, yes, concerns about whether biological rodent neural networks are or are not conscious come up frequently in the biological neural network papers. I'm not sure I would want to be a researcher trying to get an experiment past an ethics committee if my biological neural network had 25B rat neurons. (I would hope that they could not).
