Thinking of it as quantum first.

Before the 20th century, there was a preference for the idea that things were continuous.

Then there was experimental evidence that things were quantized when interacted with, and we ended up with wave particle duality. The pendulum swung in that direction and is still going.

This came with a ton of weird behaviors that didn't make philosophical sense - things like Einstein saying "well if no one is looking at the moon does it not exist?"

So they decided fuck the philosophy and told the new generation to just shut up and calculate.

Now we have two incompatible frameworks. At cosmic scales, the best model (general relatively) is based on continuous behavior. And at small scales the framework is "continuous until interacted with when it becomes discrete."

But had they kept the 'why' in mind, as time went on things like the moon not existing when you don't look at it or the incompatibility of those two models would have made a lot more sense.

It's impossible to simulate the interactions of free agents with a continuous universe. It would take an uncountably infinite amount of information to keep track.

So at the very point that our universe would be impossible to simulate, it suddenly switches from behaving in an impossible to simulate way to behaving in a way with finite discrete state changes.

Even more eyebrow raising, if you erase the information about the interaction, it switches back to continuous as if memory optimized/garbage collected with orphaned references cleaned up (the quantum eraser variation of Young's double slit experiment).

The latching on to the quantum experimental results and ditching the 'why' in favor of "shut up and calculate" has created an entire generation of physicists chasing the ghost of a unified theory of gravity while never really entertaining the idea that maybe the quantum experimental results are the side effects of emulating a continuous universe.
