But part of the whole point of listening to music is enjoying the expression of the people playing the instrument. Music is much more than just the final output of a machine, it's an expression of the soul. You may be able to create music more easily with this tool, but I guarantee it will be soulless, just like Google.
The results certainly will not be better. They will be a hideous amalgam from a computer. Just listen to real music created by real people (preferably live) and you will know how hideous these results really are.
Everything, even EFFICIENCY, has its limits to how much we should have.
