I agree with you that there is some "building up" required to create a full
and rich human experience, which cannot happen in a single instance or with
a single CPU instruction being executed. However, where I disagree with you
is in how long it takes for all the particulars of the experience to be
generated from the computation.  I don't think it requires re-calculating
the entire history of the human race, or life itself on some planet.  I
think it can be done by comparing relations to memories and data stored
entirely within the brain itself; say within 0.1 to 0.5 seconds of
computation by the brain, not the eons of life's evolution.

So perhaps we are on the same page, but merely disagree on how detailed the
details of the computation need to be.  i.e., what is the substitution
layer (atomic interactions, or the history of atomic interactions on a
global scale?).
