I argue a few points in your article, yet I am a huge supporter of a preset modular accessibility to musical creation.
The Nintendo generation is now in full control of the music software generating world. The are all game kids as well as most friends without computer skills do their first electronic music in fruity loops and garage band.
The industry has nothing to do with music. For example ask any passionate musician about how many side jobs they do to get the time to do what they love. Sure the industry can find talent anywhere. But talent in market standards is just somebody who can recreate the style and taste of a popular demand. Culture is not reinvented by copying, just because we invented the stamp tool. Creative work is multi dimensional not necessarily multi player and a proper entertainment experience luckily and forever will involve the body of your audience and the excitement of sweat and body odors of random people. How you make your music really doesn’t matter that much. Trust me, here in Berlin people believe machines can make real music more than anything, yet how many musicians do you know coming from this town.
Leonard Coen did his best songs to a Yamaha toy keyboard accompangiato mode and a chord automatic.
So the tool you describe also has no novelties. Even able ton live has more accessibility in terms of quick access. The interface is the key, and that interface ain’t interesting what so ever.
An instrument is lasting because it is fun and gives you long time feedback. Where is the feedback exciting in the loopy linear narrative you describe? Loops are a limitation that bands like the klf utilized to make their ironic Joke number one hits in the verge of the 80s because that was high tech recycling culture back than. Hip hop producers are as simple minded and trained as a kid you describe. Roger Linns mpc is seriously a progression, able ton was, Mario paint was, granular labs and visual feedback interfaces that use gestures are, but come on, anybody with a fundamental understanding of logic ( and even better if they gained it by playing mine craft) can build and recreate the digital tools eventually required for their creations.
You talk about markets, not progress.
