Science is interesting, because it is at the same time the method and processes, and I think also a vision of what search for truth should be? An expert in that case is (always?) a scientist. When considering art, experts aren't always artists, they can be pure researchers (for some odd reasons I was at a point familiar with people from the art history academic world in my hometown, they weren't artists at all but had a lot of context to provide when discussing an art piece). But maybe it is just different types of expertise. In any case I do think there is value in the link you're making
