...for anything other than the field where the pattern makes sense, of course

This is a dogmatic take. From wikipedia > Entity–component–system (ECS) is a software architectural pattern that is mostly used in video game development.

ECS was invented for and is primarily used by videogames. > If a pattern only works in a couple fields of application, it's not a very good pattern. I completely and totally disagree. How would you even define a "field of application" without there being patterns and practices that are unique to it? If every domain uses the same techniques, what is the difference? Off the top of my head, here are some patterns that I rarely see outside of their primary domain: Programming languages and compilers: * Recursive descent * Top-down operator parsing * The visitor pattern * Mark-sweep garbage collection and the tri-color abstraction Game and simulation programming: * ECS * Per-frame arena allocators * Game loops * Double buffering * Spatial partitioning

  Except the visitor, which can be useful in pretty much any system with polymorphism, and maybe "game loops" I definitely would not call any of those patterns ; methods and techniques maybe. These words don't mean the same thing, a pattern is much more general than a technique !

    > Except the visitor, which can be useful in pretty much any system with polymorphism In principle, yes. In practice, I've almost never seen the visitor pattern used outside of programming languages. Maybe once or twice in UI frameworks. > methods and techniques maybe. These words don't mean the same thing, a pattern is much more general than a technique ! What's your definition of a "pattern" and why wouldn't the things I list fit in it?

If it's extremely useful in a particular situation, why does it matter if it's not useful outside of that situation?
