No, none of that follows from CTM alone. Bruno is putting
forward the Sceptical Hypothesis that I am being simulated
on a UD. However, if I am entiteld to assign a very low
likelihood to that SH along with all the many others, alowing me
to know in a good-enough way that matter is real, reality is
real etc. It is very important in these arguments to distinguish
between certain knowledge and good-enough knowledge.

BTW--why doens't O's R cut away Platonia in favour of
a smaller material universe?
