Yeah ok, I get your input. The point is, that most of the arguments, that say that QM is "unintuitive", boil down to the fact that some people are simply unwilling to accept that the world is "not made of particles".

Some people adhere to this worldview like to a religion. You cannot argue with religion. Therefore, for most people, there is little hope to come to terms with QM. However, I am saying, that if you "give up" on a particle worldview, then QM isn't so super weird as lots of people always make it seam.

Yeah, there's some strange issues going on. But I'm saying, that a lot of these aren't so mad to think about if you give up on your particle worldview. Coherence, for example, boils down to a system which isn't simply described by "that atom goes there and this atom goes here". It's different, but consistent. It still reveals a consistent model with a measurable outcome. Just that this model is like taking public transport instead of riding your own car. Sometimes, you gotta mix things up to see the bigger picture.

QM is the only bit of physics where something can still be both physical and have zero information content. Therefore it's the only place where the difference matters between C being a universal Vs a limit for information.

Also waves are non local, an exponential decay never actually reaches zero. Accepting this is critical to QM making sense. It's just very alien to our natural sensibilities.

As for the conflict with GR, both theories are known to be incomplete since neither predict each other. Knowing how both differ is one of the few known holes in physics. Interestingly, both theories are ridiculously accurate, within their domains, making the job all the harder.
