I don't believe that I experience qualia.

Meaning you have no experiences, or your experiences have no particular character or flavour?

From inside the neural network, blue doesn't feel like it's just a number in it's input, or that it's thoughts are just a bunch of multiplications and additions. Blue would feel like, well, an indescribable phenomenon. Where it lights up it's "blue" neurons, and everything associated with them. It could list those associations, or maybe recall memories of blue things it has seen in the past. But it wouldn't be able to articulate what blue "feels" like.

Which experiences would you expect to be easier to describe..novel ones, or familiar ones?
