Been reading up on Heraclitus lately?

While this is an interesting statement for a philosophical dialogue, it doesn't really make much sense in the context of programming, where many things are constant, many things are not processes, and there are plenty of use cases for both mutable and immutable state (which is exactly why I always get really defensive reading articles like this one, that pretend all problem domains would be best modelled by a single programming language/paradigm/model of computation).
