This hobby is similar to running a manufacturing plant, it’s a game of bottlenecks in a quest for velocity/ perfection. Each rectified bottleneck, creates another bottleneck, as it can only be the case. At some point the listener’s hearing will become a bottleneck, and is/will be assisted/solved as technology advances. The flow will evolve and continue.
Mapping and measuring the flow of a manufacturing facility may be easier. Either way, solving the impediments will always be a challenge, otherwise they would not be impediments.
The issue to me is one of priorities, as resources (time) is limited, and so far, as far I know, the bottleneck of death continues to elude us, at least on planet Earth.
Sometimes I feel the goal of this hobby is to take a picture of a painting that is superior to the original work.
