I would say that this proves that dicts and complexes are more
general, rather than more fundamental. The fundamentals of boolean
logic are AND/OR/NOT, but it's common to build everything out of the
more general NAND gates because they can do everything. (I may be
sketchy on details there, I'm a software guy not a hardware designer.)
