Generics in Go are very helpful for my team. They allow us to create reusable functions in common libraries in our monorepo that are simple to reason about and easy to read.

For instance, we have an internal library that helps us create and perform common operations on concurrency-safe maps. Being able to pass and return arbitrary structs to/from those functions has made our codebase much cleaner and easier to work with.

Please take my response with a grain of salt, as we have not benchmarked or otherwise compared (via escape analysis, etc.) those generic functions against any non-generic equivalents.
