Sure it isn't art but I guess it will be a substitute for art for many things: do people care that much if their workout music is actual art or artificial not-art art-like stuff?

I would guess that if there are economies of scale, concentrating production lowers the average unit cost and thus lead to more profits and thus more capacity for investment into R&D.

If, say, all steel production was done by 1-employee companies competing against each other, I don't think any one would be able to afford any serious investement.
