The question is if consciousness only exist on this level.

We know that ant hives have a hivemind that is not present in the individual ant. Similarly humans can also be observed to create a zeitgeist on larger than the individual scale. Even individual humans pass through different states of consciousness from birth to death. So it very much seems that consciousness is scalable. So where are we on that scale, can it be scaled down as well as up?

Most things in the universe have recursive properties. They can be scaled up and down or be understood as the sum of their parts. Saying that consciousness is an emergent property is no different, but it's sort of dodging the question just as badly as someone saying it's a magical new law of nature.

Perhaps AI can help us determine what the minimum number of required parts to create the emergent property is and why it isn't present in the same setup with just one less part, or with a different complexity. I doubt we'll find the answer, but it might lead to some better questions.
