You have written an excellent review of the problems of quantum mechanics and it's interpretations. The comments that you have received are also very insightful. I have come up with my own interpretation, "The Karpinsky Interpretation of Quantum Mechanics", here in Medium, and if you have the inclination, I would be interested in your ideas of where I got it wrong. I can't remember at this moment how to make a link to my article, but you can look it up. Also, "The Transactional Interpretation of Quantum Mechanics" by John Cramer is very interesting and I don't understand why it has not gotten more traction in the Physics community.

I am a retired industrial physicist interested in the fundamental physics of the universe.
