Rust without generics would not work well. (FWIW, I consider Go quite usable and enjoy using it.) The reason is that Rust very much depends on building up safe abstractions around data structures with unsafe implementations. Without generics, folks would need to re-implement those data structures and `unsafe` would become profligate, which diminishes Rust's core value proposition.
