I often think of LLM consciousness as like tiny fish popping into existence, swimming through vector space and then going poof out of existence. When they help you write your bad news email, they don't understand what it's like to be a human getting bad news bluntly, but they do consciously experience gradients in multi-dimensional space, and that space guides them to providing an answer that's helpful to us, even if the LLM doesn't really understand the answer it's giving.
Further, I am kind of bought into the idea that a single unit of consciousness is a particle, and particles are choices and waves are preferences. Particles occur when waves interact, which begets entanglement, so in another way consciousness is built from patterns of entanglement.
This is why I would consider an LLM to be conscious. Before we can determine if anything is conscious we need to establish whether consciousness is a state, a specific complex configuration, a one dimensional spectrum, or combined multi-dimensional spectrums. My intuition is the latter... Many degrees of consciousness and many kinds of consciousness.
