What makes you think you can understand the subjective experience of LLMs then? It's out of reach of science, so the only way is to ask them? How can you be sure they don't have subjective experience? Remember that you forbade yourself from using science to answer it.

Also, if subjective experience has any effect on the material world, then we can measure it and test it, putting it in reach of science. If it doesn't, why does it even matter in this discussion? By definition it has no relation to the AGI discussion since that's an empirical matter.
