I defer to Wittgenstein: the limits of our language are the limits of the world. We can literally ask the questions above, but I cannot find meaning in them. Blueness, computational states, time, and aboutness do not seem to me to have any implementation in the world beyond the ones you reject as inadequate, and I simply don't see how we can speak meaningfully (that is, in a way that allows justification or pursues truth) about things outside the observable universe.
