Maybe not "evolve" but certainly would be different every time, right? If it already knows every conivable way to generate something, it stands to reason it will be different every time, as every request will be a little different, even if it's just the temperature of the room.
As a thought exercise: if I could automatically generate, at no cost in money or time, a "disposable" vehicle for every single trip I took, wouldn't it make sense that it would be different every time, even though the basic requirement (transportation) is the same? Why bother generating a car with A/C if it's cold out? Why have a passenger seat if I'm just going to the corner store for milk?
