We don't know what consciousness is. But if we're materialists, then we - by definition - believe it's a property of matter.

If LLMs have a degree of consciousness, then - yes - calculators must possess some degree of consciousness too - probably much more basic (relative to what humans respect as consciousness).

And we humans already have ethical standards where we draw an arbitrary line between what is worthy of regard. We don't care about killing mosquitoes, but we do care about killing puppies, etc.
