It really depends on the medium. Writers can continually improve and refine their skillset throughout their lives and that seems to be the case throughout history. Whereas musicians seem to either lose inspiration or interest as they get older, maybe it's just a medium that benefits a lot from the enthusiasm and discovery of youth. That being said, I do suspect there will be a much greater number of people emerging at older ages over the next few decades as more people opt to not go down the typical path of obligations and more flexible work situations allow for more time to focus on passions (for those who can afford to not be working all the time)
