From the abstract it sounds like the author here is drawing a false equivalence between consciousness and intelligence. Reading more into the article, it really sounds like this is the case. More specifically, it sounds like the only connection between intelligence and consciousness comes out of some pretty strained definition usage. Digging deeper, the issue I see with this essay is that to accept the end conclusion…

We could say the brain is conscious but what about all the unconscious influences it apparently receives from gut flora? And gut flora are affected by what we eat and our culture. So where do we draw the line? Are you sad today because of bra…
So much effort is spent trying to pin down a definition of consciousness. Ask five people and you'll get five definitions. And yet everyone is so sure they know who has it and who doesn't. Slugs don't have it, dogs don't have it, maybe elephants do? Apparently they can talk to each other and mourn the dead.
One possible motive behind humanity's fascination with consciousness, and our speed at assigning or withholding it, is that it gatekeeps the belief in an anthropocentric universe. The human experience is the one we understand, and if you don't have it you are not conscious. Consciousness then, is a Turing test for how passibly human you are. Slugs could get some of the consciousness table scraps if they'd only mourn their dead.
As we learn more about other species; and coming from the other end too as computers (big data really) reveal new sightlines on human determinism; consciousness as a metaphor is strained and loses adherence.
