Then why didn't Plato discover Quantum Mechanics 2500 years ago? Because no sane person would propose such a crazy idea if they weren't forced to do so by the crazy outcome of certain experiments.

He did! The shadow cast on the wall of the cave was something he was prepared to doubt. Just as, much later, Young's two-slit experiment cast the shadows of doubt about the structure of reality. He was prepared to doubt common sense and indeed the evidence of his senses. He was in an Everettian/Galilean headspace when he did that. He found a much larger reality must exist than is more real than he could perceive. He may not have formalised it but he could not ignore it. Plato didn't so much discover QM as fall headlong into it.

Absolutely. Doing this was the real beginning of science, without which QM would never have existed, except that another Plato would have probably discovered it.

Then Aristotle made a simplification, which unfortunately has become a dogma for the Church, and seems to remained as something taken for granted by most: primitive materiality. But at least now we know that it does not work well with both theories (computationalism, QM) and fact (quantum weirdness).

People might read the books by d'Espagnat, on the foundation of quantum mechanic, to find arguments which are independent from comp that QM leads to Platonism. reality is not WYSIWYG.
