I have an idea after reading this, but how would you react to Yuval Noah Harari's definition?

"Consciousness is the biologically useless by-product of certain brain processes. Jet engines roar loudly, but the noise doesn't propel the aeroplane forward. Humans don't need carbon dioxide, but each and every breath fills the air with more of the stuff. Similarly, consciousness may be a kind of mental pollution produced by the firing of complex neural networks. It doesn't do anything. It is just there."

I've always enjoyed Bill Hick's quote. "We are one consciousness experiencing itself subjectively." I've experienced it many times on psychedelics. My sense of consciousness doesn't feel like it belongs to me any more than the people around me. Or even sober, thoughts arise that don't feel like my own. They just flow through me, and my experiences shape how I act on them.

This discussion is interesting to me, as a plant biologist who has enjoyed following my colleagues argue about whether or not plants have consciousness (and intelligence . . . And a nervous system). (See https://www.nytimes.com/2018/02/02/science/plants-consciousness-anesthesia.html for one of the issues they are fighting about). The “what it’s like to be” definition doesn’t really seem to help here. How would you apply this definition to non-humans?
