Not all elements will make this journey. Not all should. Those that do are among the most valuable legacies of the projects that spawn them. Objects help shearing layers to emerge, because they provide places where more fine-grained chunks of code and behavior that belong together can coalesce. The Smalltalk programming language is built from a set of objects that have proven themselves to be of particular value to programmers.
Languages change more slowly than frameworks.
They are the purview of scholars and standards committees. One of the traditional functions of such bodies is to ensure that languages evolve at a suitably deliberate pace. Artifacts that evolve quickly provide a system with dynamism and flexibility. They allow a system to be fast on its feet in the face of change. Slowly evolving objects are bulwarks against change.
