As I (attempt to) follow the discussions on various QT threads here on PF, many of the subjects being discussed are frequently categorized as being an "interpretational" matter. Typically, this assertion is then followed by some statement that the formalism of QM remains the same regardless of interpretation. When I look into the various interpretations, they all have aspects that I find compelling, but I definitely feel like I'm missing important features of the concepts. I've heard it said that ALL interpretations of QT have their "warts". I thought it might be educational if the experts in the room explain what the warts of the typical interpretations are that prevent them from being more universally accepted by consensus opinion.
