As a counter-point, OOP isn't necessary for dynamic dispatch.
None of these dynamic features you describe are necessarily any harder in non-OOP languages — or easier in OOP languages.
You can do the same kind of dynamic dispatch in Elixir, Go, etc.
OOP really is a preference, not a differentiator.
Source: I cut my teeth on OOP and used it for many years. Been using Elixir for the last half a decade, and have zero loss of ability to do things like this.
