Jack Vance (namesake of Vancian magic) introduced two interesting concepts in his Dying Earth series. In earlier books magic was essentially invented by the ancient masters who were expert logicians and scientists. Each spell was essentially a proof of concept that a sequence of actions compelled reality to act in a certain way.
By the time of the first short stories in the Dying Earth series, mankind has long since deteriorated due to an overreliance on what is essentially magic to the layperson. Even the wily magicians of the modern time are only capable of rote learning a few arguments at a time; hence the fire and forget Vancian magic system of old D&D.
In later books, magicians have returned to near godly power. They've somehow found a link between djinn-like creatures capable of controlling portions of reality, and the rote rituals of old. They've learned to essentially cut out the middle-man and directly enslave these djinni to do their bidding.
