Everyone was still off inventing their own wheel 10-15 years ago. Today, most languages provide libraries that cover the majority of the use cases for which you would have written your own implementation of a design pattern. To add to this, languages have shifted towards providing functional programming extensions that move away from the OOP perspective on design patterns to a functional one.

In a sense, design patterns are everywhere. Some easy examples: each time you use a foreach, you are using the iterator pattern. If you use filter or Where on a collection, you are using a visitor pattern implementation.

I would add that people are coming to realize that SOLID principles lead to code that is easier to write, reason about, and maintain. Whereas the GoF patterns were the right knowledge 10 years ago, SOLID principles are the right knowledge for today.

Basically this. I do see the facade pattern used a lot in projects still however.
