> we're on the very lowest bottom level of the sentience hierarchy I don't have proof of this, but I think most creatures have some amount of awareness, progressively decreasing as you descend the great chain of central nervous system complexity. Probably decreasing quickly at first, from humans to primates to regular mammals, and more slowly afterwards, until asymptotically vanishing into virtual nothingness as there's no complex nervous system to speak of anymore. Perhaps we're at the bottom of the interval of what could be called truly self-aware consciousness, as opposed to, I don't know, maybe somnolent or lethargic or dimly awake consciousness. With that I would agree. Which of course automatically raises the question: why should the ascending arc stop here? And what do the next levels look like? Probably impossible for us to imagine even in principle, but still.
