Of course a human brain without neural activity is not concious at that
moment -- then again, that human brain won't be using these 'lookup tables',
since a human brain without neural activity hardly is having any activity at
all (ex definitio).

But I still don't buy -- myself -- the argument that the consciousness or
not of an entity relies entirely on their internal representation; that is,
whether they react according to a lookup table, or according to some
mystical other.

This mini-sim, how is it built? What does it do? What tells you that it
cannot be equivalent to some sort of 'lookup table'; to some sort of
function mapping the input (that is output from the first function) to some
sort of output (the desirability rating)?

It still seems to be two functions; that are composed in order to form
'consciousness' according to you -- so what says that this composite
function isn't conscious in itself?
