I think this discussion was birthed because nature repeats itself a lot. I’ve studied biology, so my example relates to that: anatomical structures that evolve completely separately of each other perform the same function, (ex. mollusc eyes and mammal eyes, or butterfly wings and bat wings) and structures similar in evolutionary origin perform different functions, for example (humans have fingers, thumbs and toes, horses have hooves). Physics principles are the same way… of course there are similarities and familiar repetitions in the ways black holes and eyeballs work: the similarity is the nature of light, and the lens effect, not the black hole.
