How about "We remember the past not the future hypothesis."

This is part of something more general. Programmers tend to write
functions that return objects. Once these objects are created they
are rarely modified. So a constructor can put references to older
objects in a new object but if you never modify the new object only
pass it around as a value its references can only point backward.

How about the "Functional programming is the norm, side effects the 
exception hypothesis."
