It is! But in Rust you still have an escape hatch in the form of the `unsafe` annotation which allows for mistakes which break memory safety. I don't think Go has something like that, unless you use the FFI. So saying that Go is at least as memory safe as Rust might not be too wrong of a statement.

However I think in total Rust is safer. E.g. Rust prevents a ton of race conditions in multithreaded code, which Go can not do.
