But does the fact that machines can also create works of music and art make it any less enjoyable for humans to create them? Will we suddenly stop writing or drawing for pleasure?
Related to instruments themselves, the trial and error is one very important aspects I can think of right now that's enjoyable: playing something off beat or out of tune and correcting yourself. The feeling of correction and improvement.
It is a real pity the actual algorithm itself has no way to enjoy what it is creating.
