The question is, what is simplicity?

Go tries to hide the issues, until a data loss happens because it has had trouble dealing with non-UTF8 filenames and Strings are by convention UTF8 but not truly and some functions expect UTF8 while others can work with any collection of bytes.

Or the Go time library which is a monster of special cases after they realized they needed monotonic clocks [1] but had to squeeze it into the existing API.

Rust is on the other end of the spectrum. Explicit over implicit, but you can implicitly assume stuff works by panicking on these unexpected errors. Making the problem easy to fix if you stumble upon it after years of added cruft and changing requirements.
