 The point of the use of an abstract framework is not to give empirical predictions. This is the task of specific realizations inside the framework. The framework of dynamic semantics (i) provides a direction of thinking and (ii) allows us to import methods from the mathematical study of the framework. It follows that the question whether natural language meaning is intrinsically dynamic does not have an empirical answer. Still, what can be said is that the study of interpretation as a linearly-ordered process has proven quite fruitful and rewarding.
