Look at the producers and studios that put out hit after hit, artist after artist. They find someone with a good look and basic competence and they can turn them into, if not stars, at least solid acts.

Their skill isn't performing, it's knowing what people want. They can listen to a hundred demos in an afternoon and pick out the 2 or 3 that have a shot. Now they can skip the submission process and just create it themselves. The basic competence will always be there, but their main skill - knowing what people want - still applies.
