The problem with invariants is that they change over time

The linked article is about the challenges of maintaining invariants in complex systems. It discusses how the concept of invariance, which is often seen as a desirable property in software design, can actually become problematic over time as systems evolve and change. The article emphasizes that in the real world, nothing is truly "invariant," and that attempting to enforce strict invariants can lead to brittleness and a lack of adaptability in software systems. It suggests that a more flexible, adaptive approach that embraces change may be more appropriate for dealing with the inherent complexity of modern software systems.
