"the real world (and machines) are stateful/not functional"
This could be argued as being totally wrong philosophically, and is certainly not a proved statement.
I could say that state is only the creation of the human mind in a world that is essentially made of movement, in order to understand it and quantize it. Even matter at the lowest level is the movement or particles, almost as much as it is the particles themselves.
This point is not without link to the current argument about functional/imperative programming, and certainly shows that your view of the matter, while not false, is certainly narrow minded.
