is it? I've heard that about Go, not so much Rust. cargo doesn't statically link system dependencies by default, only other rust dependencies.
Go binaries are statically linked by default if they do not call out to any C functions.
Go will automatically switch to dynamic linking if you need to call out to C functions. There are some parts of the standard library that do this internally, and so many folks assume that go is dynamically linked by default.
Maybe it's been fixed since, but I wouldn't assume Go doesn't have any C dependencies.
