But if and when you go there and read the work in which these old people said what they believed you got convinced -- and you barely know that you are convinced of the same points you in the past found ridiculous under the guidance of your primary teacher.
Thousands of people of equal brilliance have come up with vastly different explanations for what appears to be the same thing. As a conclusion they must all be vastly overconfident.
I also think there are a lot of people who say more than they know, on both sides of the argument, but that's true of any subject.
For example, the failire of the Michelson-Morley experiment is the basis for relativity and their test equipment was essential for QM!
LIGO, for all its complexity, is just the Michelson-Morley experiment again, this time sensitive enough to detect waves in the ether rather than drag from our motion. Of course we've switched a lot of terminology around since then, but the idea is the same.
Similarly, interferometery is integral to QM studies, and is a critical tool of modern science.
It seems you already discounted most of them and chose the one most comfortable to you.
