Actually, all three are correct, but different ways of saying the same thing.
What do you mean by the phrase 'fundamental substance'? Are you sure that it is even a meaningful concept?
Isn't it rather the case that all three have practical applications, they all get results, but none gives a true description of reality at the subatomic level? They don't, for example, fulfil Einstein's aspiration that "the programmatic aim of all physics is the complete description of any real situation, as it supposedly exists".
I'm sure you're familiar with the statement attributed to Feynman and also David Mermin, that the Copenhagenists approach to QM could best be characterised as "shut up and calculate". And why not if that approach works so well in developing new technologies?
Only that hasn't satisfied those who want to know what QM
means for the material world. Beginning, presumably, with wave/particle duality.
"Quantum mechanics is the most useful and powerful theory physicists have ever devised. Yet today, nearly [100] years after it's formulation, disagreement about the meaning of the theory is stronger than ever."
- N. David Mermin
You're right, I'm not sure if "fundamental substance" is even a meaningful concept. If it isn't, does that mean that fundamental particles may in fact be abstractions? And if that is the case, is our entire universe constructed from abstraction and metaphor?
Mermin again;
"Having once removed the mystery from electrodynamics, let me immediately do the same for quantum mechanics:
Correlations have physical reality; that which they correlate does not."
Whatever mystery that observation removes, it seems to open the door to a galaxy of new ones.
