I think it's worth emphasizing that ALL models ignore some
real-world complexity.  That's what modeling is all about. 
It's not a shortcoming of existing models but an essential
characteristic of them.

Different models are appropriate for different tasks.  A
model that captures complexity relevant to all tasks will
probably be appropriate for no task.

Instead of trying to come up with models that everyone can
agree upon, it seems to me to be more worthwhile to come up
with families of related models, and a framework that
enables agents employing different models to communicate.
