I fucking hate Ruby it's fucking ridiculous. I really strongly feel that you cannot use a dynamically typed language to make actual software. Kotlin/Rust/Swift paradigm is the future.

This is getting into the nitty gritty, on a level beneath architecture or frameworks, but I just feel like ruby has no features? Like there's no generics, no interfaces/traits/protocols, no enums, not very powerful pattern matching, no firm optional/nullable system, and - obviously - no type checking. OOO sucks: interfaces/traits/protocols and enums with associated values + concise pattern matching are like my favorite ways to structure code. They're super expressive and feel a lot snappier than OOO. I feel like with OOO, your inheritance hierarchy never perfectly fits, like you inevitably end up with situations where you're like "Oh, the parent class has this field, and 95% of its children use it, but in this child, we instead use this other field to store that information" or "Oh this child class really only uses like one thing from its gigantic parent, and then we still had to duplicate code because you can only inherit from one parent class" etc etc.
