I think Rust strikes a nice balance but there’s enough magic that some people still get frustrated. Following traits can get tedious at times.

Yes, which is why there's progressive modes of compilation to not allow anything ambiguous if that's what you want (i.e. an enterprise codebase).
But, a junior can still try things out in weaker modes of compilation, and then once they've got something working, it is typically very easy to do the pedantry to remove ambiguous behavior.
