Paradoxical traps or thought experiments filled with holes?

MW is even more undefined in terms that we cannot even construct a measurement/singular interaction... (it is always derivative of total system state)

I mean it builds the term "measurement", which is an undefined and unscientific concept, right into the laws of physics. Personally, I find this to be virtually nonsensical.

Both surveys are fascinating reads. They clearly give a sense that despite of the spectacular success of QM how far we still are from the final word in that field.
