The wording you used and the fact that your post was a completely off-topic opinion, just to attack the language you don't like. We're discussing various null-safety approaches here, not opinions about which language is better. That Kotlin can't treat optional types as any other monad (e.g. Either or Try monads) unlike Haskell, Scala and probably half a dozen other languages is a fact, not opinion. Also baking optional types into the syntax and the type system makes them language more complex and this is also a fact.
