[ExI] More thoughts on sentient computers

[Giovanni Santostasi]

Brent you are fixated with Qualias.
Qualia is one of the silliest idea ever. It doesn't matter if it RED  or
RED. It really doesn't matter. It is a label.
It is not different from use 2 or two or II.
We think that experience of redness is important because.... it is inside
us or it is irreducible. Of course it is not irreducible there are 1000s of
variations of red and most of us call them red.
Eskimos have dozens of words for snow that correspond to finer experiences
of snow they pay attention to and we don't. It is not different from all
this fuss about red.

The red we see is just a label that our brain associates with ripe red
fruits. It learned to make that association so it seems special to us. In
fact this how as primates we are so fascinated by red in particular. It is
just a color but there is a reason red is often the color used by Qualia
fanatics.
But it is the same with the other main colors, they are associated with
given experiences in the world. The entire qualia business is again another
of these navel gazing exercises by philosophers.
No, physicists understand well what colors are, better than philosophers,
it is that most of us think that qualia is a stupid idea that really means
nothing and for sure it does not have all the depth that philosophers think
it has.
