Thank you for your efforts in trying to keep this on topic.Please do not clutter the thread with further discussion of the mind-body problem. That is off topic for this discussion. Please focus on the OP question, which was about the pros and cons of the Copenhagen Interpretation of QM.
My original thinking was to start a thread for each of the interpretations and see what arguments there are for and against each of them, but I recently discovered your insights article The Fundamental Difference in Interpretations of Quantum Mechanics and I think that frames the question I had in mind, in a much more concise manner. Would it be OK to start a new thread on the pros and cons of instrumentalist interpretations vs non-instrumentalist ones?
Your article gives great insight into the question but I would love to ask a few more questions in that direction. I don't want to spam the forum with multiple threads but the thread title of this wouldn't really capture the broader question.
