In theory, that's true.
In practice, any unexplored corner of the field will contain surprises; these will require extra theoretical development to cover.
Usually things like imperfect understanding of materials get in the way. Pretty much the reason you need both theory and experiment to make progress in every single area of matter-based technology (i.e. not software).
