Starting from the answers to this question, even people not familiar with the interpretations of quantum mechanics can understand that physicists are not interested in substance metaphysics. This is understandable, as the scientific method requires experimentally verifiable predictions. But the result is a quite unsatisfying lack of answers to the "why" and "how" questions inherent to our nature.
I was attracted to science from an early age, because I had seen that countless key questions could be answered unequivocally. I was initially surprised to discover the limits in understanding we had hit with QM. But I was actually annoyed to see that the people most qualified to provide answers that could help make sense of the quantum weirdness had given up for decades. I now understand the reasoning, but will never accept that "x just is and doesn't make sense" or that "y can never be understood". It sounds too much like religion's cheap cop-out that our minds can't hope to understand God.
So who does the task of tackling these hard questions fall to? Scientists who dabble in philosophy and aren't afraid to publish unscientific theories? Philosophers who dabble in physics or read popularized versions of experimental results and interpretations of QM? Or has the academic community overall decided to give up on substance metaphysics? So we leave it to journalists to take interpretations like multiple worlds and present them as reasonable explanations of how the universe works? (I know the math for MWI works out, but I personally find it a ridiculous theory, that took Occam's razor and used it to shear sheep)
