It seems that way to me too but it (i.e. the notion that QM is needlessly complex and akin to the Ptolematic system) is nothing but conjecture without some candidates for assumptions that might need to be challenged. [edited for clarity]

It's quite the opposite. QM was discovered while we were trying to resolve certain problems such as the ultraviolet catastrophe. [0] To say it is "nothing but conjecture" is incredibly condescendingly dismissive and ignorant of the history of its evolution. [0] https://en.wikipedia.org/wiki/Ultraviolet_catastrophe

I think the commenter meant that the notion that QM is needlessly complex and akin to the Ptolematic system is nothing but conjecture.

QM is obviously very true in the sense that it makes useful predictions (in that sense, truth is somewhat a quantity). But it is arguably very inelegant in its seemingly ad-hoc introduction of probability. Naturally, one would hope to one day get a more principled explanation of this randomness. What would be needed to make physicists search for such an explanation? Some kind of pattern in the "randomness"? Say, phot…

The probabilities spawned QM, not the reverse. The modern interpretation of QM is a reification of those probabilities - an insistence that they aren't the results of a process, but are just probabilities, irreduceably.

Has anyone ever considered that perhaps the particle/wave actually goes back in time?

There was an Israeli team that "proved" quantum particles can go back in time by linking groups of entangled particles that didn't exist in parallel.

Would have to look for the link, and don't know if that was ever rejected, but.. maybe?

By extension, spooky action may be ignoring time entirely.

Yes, thanks, I edited out the ambiguity.

The problem is the insistence on the existence of particles at the quantum level. We know that quanta propagate like waves, but interact with classical level systems in discrete units. So we need to stop believing in discrete particles with distinct properties at the quantum level and come up with an explanation of why quantum waves appear particle-like at the classical level. Probably the answer will involve the way in which de-coherence occurs when a large number of quanta are involved.

And it's not just like people found these probabilities and then decided to stop trying to explain things and said "what if these are just how physics worked". Instead, people found that any attempts at removing the probabilities (through local hidden variable theories) ended in contradictions, and then accepted that they must be fundamental.

Local hidden variables as an explanation has been experimentally refuted: https://en.m.wikipedia.org/wiki/Bell%27s_theorem
