Not everyone wants nor desired to use a functional language. They might want or even need an imperative (and procedural) language. Odin is an imperative procedural language, and has no "functional programming" aspects to it. Odin is not of that tradition.
If you love functional programming languages and they are useful for solving your problems, then Odin is not the language for you, and that is absolutely great! Odin is for people who wanted a C alternative for systems-level programming, and thus an imperative procedural language is what they desire. And as such, Odin is not a mixed-paradigm language either, since it does not make sense for it (e.g. explicit manual memory management, imperative style, etc).

Isn't it great that there is choice now between programming languages?---in the domains people work in.
