Thanks for taking the time to read the article and continue responding. To progress further, maybe the idea I need to address is distinct points vs gradation.

Would you agree in music that there are limited factors involved in what makes a song? There are probably more than I can name (rhythm, chords, melody, instrumentation, etc), but there is a limit to how many factors are at play. These factors exist in limited distinct manifestations but that have infinite gradation. For example, look at the factor of instruments in an orchestra. There may be infinite gradations of each type of orchestral instrument (in the sound that it makes), but there are not infinite distinct types of instruments. Think about why there are around 24 instruments (I believe) in an orchestra--there are infinite gradations of instruments but a limit to distinct instruments.

The laws and matter of the universe manifests itself into limited distinct factors at play in music, which then manifests into limited distinct songs (those combinations of factors that produce a musical effect on a human being--related to our hearing and mental nature).

Within those possibilities of combinations of musical factors that can be put together and called a song, not all are equal in their effect on a human being. I can play a few chords randomly on the guitar, record the audio, and call it a song. But what separates that recording from The Rolling Stones' "Satisfaction"? There are a limited number of distinct songs that we have recorded up until the present that can produce the same level of effect on a human being as "Satisfaction".

How can there then be an infinite number of distinct songs to create in the future that would have an equal or greater effect on a human being as "Satisfaction"?

Again, I'm not saying that we will stop creating music in the future. Just that at some point there will be a general consensus that our best works are behind us--the idea that "you can't reinvent the wheel". We will keep creating songs with infinite gradations, but they won't be infinitely distinct with as much of an effect on humans as the songs that came before. And while different songs have different levels of effect on different people, there is a non-perfect but non-arbitrary consensus on certain songs or artists having more of an effect than others (the extreme example being my random chords recorded have little effect vs "Satisfaction" having great effect).

As far as the utility of the idea, if we can view the sum of all possibilities as The Big Niche, then we can view all uncompleted possibilities as the remaining problems in the goal of human advancement. This can apply at a personal level to anyone looking to accomplish something great or contribute to human progress. For example, if you were a songwriter looking to make a significant contribution, it would be better to pursue an uncompleted genre (pop, hip hop, electronic, etc) instead of a mostly completed genre (classical, jazz, rock). But it also would apply to science, business, and technology: just like new instruments helped create new genres, a new technology or concept may create a new niche of possibilities in which to further explore in that field. Granted, progress in these fields already progresses in this way at an intuitive level, but it seems like having a stronger grasp of what is happening in human progress at a metaphysical level could only help (and couldn't hurt).

It also follows that if The Big Niche is the sum of all possibilities, then we could view an Ideal Niche as the interplay of the big niche with human nature--an ideal configuration of all possibilities for human benefit. So the goal of humanity would be to discover all knowledge, and then be able to remake society to find the distinct ideal equilibrium in all things. Like a great song is a distinct point in the niche of music, there is a distinct point in all facets of society as to what the ideal configuration for humans would be.
