Yes. And then the (bad ?) news is that, thanks to theoretical computer
science and some mathematical logic, this can be translated into
mathematical questions leading to difficult conjectures.
To be clear I don't follow you in case you take seriously the idea of
making first person experience primitive.
I am happy you are open to give some fundamental role to first persons
with respect to physical reality, but making them primitive would hide
the difficulties (certainly when assuming comp).
I am a realist, quasi sure about positive integers, and undecided for
the rest. I am not a physical realist but given that, possibly, all
there is are numbers I am open (like Plotinus, unlike Aristotle, but
like Peter Jones ! (alias 1Z)) to the idea that the big unameable one
is a 0 person notion. Intelligibility and sensibility should emerges
from inside like any points of view(*).
