It is seriously one of the most fascinating things I’ve ever learned about.

In a completely unscientific way, I believe it’s because we live in a simulation and the uncertainty principle is a computational efficiency algorithm. As an engineer, I would take shortcuts in order to best use resources. If I needed to calculate every particles exact position at all times that would require more processing power. By using a wave function it means you can calculate much more quickly, until a more precise calculation is required.

I personally grapple with the metaphysical implications of this for free will. I think there are other theories or evidence of true randomness (like a recent variation on a theory of quantum gravity) which could mean that we don’t live in a totally deterministic universe.

I just try to live the best life I can. My experience of consciousness is one with free will. If that’s an illusion I still experience free will so I think I can be happy with that.
