The Occam's razor favors the simpler explanation though.
Just like we stick to the "planetary orbits are only shaped by gravitational interactions" hypothesis, and if we observe deviations, we try to exhaust all possible explanations that remain gravity based before introducing the possibility of other forces at work.
Edit: to be clear, I’m agnostic on this problem. I just don’t really like the emergence “model”, where we have a bunch of supposedly non-conscious matter and if we put enough of it together in the right way consciousness just pops into existence.
