At some point the word "consciousness" loses its already muddled meaning. Humans are conscious, dogs are conscious, fish are conscious, mollusks are conscious, insects are conscious, bacteria is conscious, fungi is conscious etc.

We don't even have a concrete definition for what conscious means but we use that classification as a means to make rules about what we can and can't do to certain entities. Can we destroy an ecosystem that has been found to be full of conscious mycelium? Is that worse than if we determined it was not conscious after all? Without a concrete definition of what consciousness is, we assign consciousness to things based on feeling and on what we want to signal to other humans about these entities.
