Where does one cloud end and the next cloud begin? The boundaries and distinctive traits of clouds only exist in our minds. We can build mathematical objects that look something like clouds according to the observable characteristics deemed intrinsic to our definition of "cloud". We can't simulate real cloud systems with arbitrary fidelity because the the mathematical foundation we've invented leads rapidly to intractable computation. "But supposing we had infinite computation" is magical thinking. Still, the universe gives us clouds. It's operating on different foundational principles. Now, moving from sky clouds to things like electron clouds, we have the added problem of what appears to be "true" non-computable randomness (not just chaos) underlying it all. Many worlds doesn't rid us of the randomness problem but merely shifts it to the problem of deciding which branch we inhabit before/after an event. We can still hang onto the notion of mathematics as discovery by recognizing it as a process of self-discovery about how our brains perceive the world.
