"Creativity cannot be scaled." Actually, in the book The Song Machine, they pretty clearly show otherwise, with teams of topliners, beat makers, etc. churning out hits in a machine-like format: http://www.amazon.com/Song-Machine-Inside-Hit-Factory/dp/039...

The author probably took those quotes from an upcoming book by the same author as that New Yorker piece[0]. The book's linked in this (Atlantic) article.
