Well ultimately any useful program will use a library that uses unsafe. All I/O is unsafe at the bare metal so while you can safely wrap it it still is unsafe internallly. When talking about the usage of unsafe code in rust, we generally ignore encapsulated unsafe code in libstd since it has the same safety guarantees as tgr compiler itself. all unsafe code encapsulated in a safe API has these guarantees, but you trust libstd more :)
