I think our programming languages haven't caught up to an ideal notation of semantics of computer system behaviour at a macro level.

The design patterns (Gang of Four etc) and software architectures that are so complicated they require extreme discipline to keep understandable. (And cognitive load)

Which pattern did you find complicated? Most of them just come down to "wrap it/them with a new object to encapsulate the new/shared state or provide the new behavior". The rest are probably made obsolete by modern programming languages.

Seventyfourteen layers of wrapping is complication.
