Your insight opens a can of worms regarding intellectual property and technology's effect. Today, there are still many human hands producing art using electronic technology, and there are many precedents regarding the evolution of creative work over the past 70 years. As technology accelerates, fewer hands are needed for more and varied content. Copyright is a good example, as this could touch on lyrics, score, performance, and now the source code of the tools used to produce it, e.g., AutoTune. Add things like Blockchain, and a successful work could have a ledger a mile long with almost no one in the chain really understanding it. Of course, someone will write a program to sort it all out for laypeople such as myself. Blockchain could be a tool for 'who gets what' and other payment-related issues, but if you are a musician, it must feel like a byzantine inhibition. Someday, great musicians might also be great mathematicians, quantitative analysts, or scientists, an interesting mix.
