OOP pattern were useful for people stuck in a pure OOP language (say Java 1.4) And needed to make something understandable. Today, when many languages, including Java, have reasonable functional programming support, a large percentage of the patterns are over complicated. Just look at the list, and see how many can be replaced with less boilerplate by passing a function, doing some currying, or both.

That doesn't replace the pattern, it just does the pattern by a different name. Design Patterns was never about OOP - the publisher added OO to the title because that was the fad at the time, but the patterns happen in other systems as well, they are just implemented differently.
