You completely miss his point about the mechanisation of the human musician gesture which make it more easy to create ready-made consumers products instead of artistic creation.
For sure there is advantage to mechanisation of musical process. There is. But Beato point is not negating advantage but to point to a big unobserved problem.
I had to quit at the "Music is too easy to make". That means that people that have a talent to create music but not the technical skill to play an instrument now have an opportunity to create unique great music.
So, while that may have caused flooding of the music scene with not good, it is hard to believe that it hasn't enabled a bunch of great music to be created by non-instrument playing folks.
