This is circular reasoning. LLMs can't feel gusto because they can't feel gusto. You have any way to measure "gusto" that we're all aware of ?
If other humans ascribing the quality of something you can't properly define isn't enough then you clearly don't care about what a LLM does or does not have, only what you are convinced it doesn't have.
