was watching this and had similar thoughts. many say music flourishes when everyone can create and share at ease, but I disagree. It only does as a market, not ad an art. 
The dedication necessary to explore creatively and reach higher highs must logically be reduced with the absence of effort, right? The Beatles were explorers in the studio, but they used tech of the time in unprecedented ways (i.e. downmixing/layering on tape) not standartization in form of plugins and presets. They fooled around, spend tons of time and effort and ok, were geniuses. which might have helped.
I also agree with AI being inevitable, thus intensifying the devsluation of music as an artform. However, I don‘t think #Bitcoin has the potential to fix this (as of noe). Most bitcoiners right now seem to repeat any cultural dilemma the fiat-standard has gotten us into, with the only difference of holding bitcoin as an asset (to pay for all the greed of future-self). 
Actual rethinking of human action through bitcoin will take much longer than money deflation, I fear. By latest that time if not already, I guess music is dead.
