Okay, I was mostly trying to clarify the terminology. The problem is
that sometimes you use "comp" as if it is the same as computationalism,
and sometimes it seems to include these additional concepts of the Church
Thesis and Arithmetical Realism. Maybe you should come up with a new
word for the combination of comp (aka "Yes Doctor") + CT + AR. Then you
could make it clear when you are just talking about computationalism,
and when you are including the additional concepts.
