It's been awhile since I thought deeply about epicycles, but if my memory can be trusted... They weren't incorrect. They did a decent job of predicting the motions of the planets given the assumption that Earth was pegged at the center of the coordinate frame (which then required a whole bunch of "hidden behavior" in terms of non-apparent phenomena dictating the rotation of all other bodies).

Re-framing the whole system to be heliocentric allowed for the massive simplification of Kepler's Laws (and, not too much later, the further simplification of describing Kepler's laws via Newton's law of gravitational attraction).

We currently have an understanding of QM that doesn't reconcile well with macroscopic observation and requires a lot of intuitions to be broken (including, possibly, the singular nature of existence, time-forward causality, or lightspeed-constrained information locality). I can't help but wonder if there's some equivalent to "Assuming Earth is the center of the coordinate frame" that we currently do that forces these unintuitive (though working) solutions.

The solar system moved in epicycles because "it just did," until several leaps of intuition allowed us to see how it didn't. I wonder if there are similar leaps of intuition waiting on the horizon to allow us to explain quantum entanglement without nonlocal information sharing (hidden variables, we have shown, is not it).

Why should physics care about human "intuition" at the macroscopic level? That's an incredibly anthropic point of view to take on a cosmos that couldn't care less if we didn't exist.

When Newton developed the theory of gravity it wasn't intuitive that all matter in the universe attracts all other matter. But also wasn't incompatible with our intuitions---it was learnable.

What I see in QM right now "smells" like we're having to compromise too many intuitions to reconcile what the experiments are showing us with the way we expect the universe ought to be working. I agree that the universe is under no obligation to work the way we expect it to---problem, what we have right now in QM is a lack of agreement on how to even rework our intuitions to match our observations and the reality the theory describes. That suggests to me that---much like epicycles, or like gravity being separated from acceleration before relativity---the stories we are telling ourselves about what we see are still too complicated, and a simpler explanation that requires us to sacrifice fewer pieces of intuition has not yet been reached.

This is, to be clear, extrapolation. I have no way to know whether such simplification exists or whether we have hit the boundary where nature actually refuses to conform in such a way to our senses and minds that we can change our intuitions to follow her. It's not impossible that this is the case. But if it is, it's a break from the pattern of physics discovery up to this point in human history.

Round Earth and heliocentrism were counterintuitive too and people struggled a lot to understand them, it's not unprecedented. Ironically Aristotle refuted heliocentrism with the same argument, that heliocentrism doesn't correspond to observation.

We have intuition to understand QM, people struggle with myths, not lack of intuition. Absence of conservation of energy is one of those myths, only those myths need to be sacrificed.
