We're living in a weak force superconductor. If we were living in an electric superconductor we'd see nothing because electromagnetic waves would be blocked from entering our eyeballs. Because we are living in a weak force superconductor, the weak force is blocked from entering our eyeballs (in fact it's blocked at all but sub-nuclear distances) and so we didn't develop weak force eyeballs.

If there's an alien living outside of the superconductor it probably has eyes that can sense all four components of the electroweak force, including the combination that we call electromagnetism, which is the only one that can pass through the weak force superconductor. Such a being would see the superconductor "material" as something like a block of red jello, only allowing one "color" to pass through and would be as surprised to see us there as we would be if we saw sentient beings inside a block of YBCu superconductor alloy.

Although we wouldn't have a way to see sentient beings inside a block of superconductor alloy, because we don't have any more long-range forces to probe it with, besides gravity. Our outside-weak alien could still see us with electromagnetism which is the one remaining long-range force we have, but that's disabled inside an electric superconductor too.
