We can account for the evolution of consciousness only if we crack the philosophy, as well as the physics, of the brain.
From what I've understood, Philip Goff comes to the same conclusions that have been formulated previously.
An evolutionary point of view is proposed to make more appropriate distinctions between experience, awareness and consciousness. Experience can be defined as a characteristic linked closely to specific pattern matching, a characteristic already apparent at the molecular level at least. Awareness...

So, I guess that I largely agree with the analysis of Philip Goff.
He uses the term 'panpsychism'. In my publication, I referred to
Griffin, D.R. (1997) Panexperientialist physicalism and the mind-body problem, J. Consciousness Studies 4, 248-268.
who also reached a rather similar conclusion and used similar terminology, apparently.
Using well defined, nonambiguous concepts could help much. I would summarize it as follows:
The discussion is not about the mystery of consciousness, but about the mystery of awareness.
Consciousness can be simply explained as being aware of awareness, and thus it is a form of awareness itself, made possible by language. Animals have awareness as well, but cannot reflect on their awareness, they are not conscious of it.
Awareness is a mystery that cannot be explained because awareness is an experience.
The mystery is that we do not understand what experience is. Experience is already present at the level of baryons (with experience being the interaction with bosons? Not explaining anything after all).
Since conciousness is a specific form of awareness (i.e., being aware of our awareness), consciousness is an experience, and that is why it is mysterious. Consciousness itself can easily be understood as being aware of awareness, made possible by symbolic language.
(Experience is meant here as 'having an experience' and not as 'being experienced', another problem caused by language.)
In fact, the tems 'consciousness' and 'awareness' are unambiguous when well-understood. 'Awareness' = being aware of, having an experience. 'Consciousness' comes from Latin 'cum sciere': knowing about.
