>Chemical engineering, on the other hand, is about analyzing systems that leak their state everywhere and have effects that feedback into other parts of the system. But it needs to be extremely efficient nonetheless. There is no isolation because it doesn't exist in real-world complex systems. Is it not possible to engineer in isolation on real world complex chemical engineering system? I try to do that with software, and most software can certainly benefit from stricter isolation (e.g. looser coupling), but most software teams - even well paid ones - often have an in-built bias against investing in less tangible work which means that you ultimately end up with these complex systems are that hard to reason about. Not that I feel like I should be complaining about this if it is indeed the reason I'm paid well.
