> Things that are hard in Rust, are even harder in C and C++.

That is not true of C++. There are many valuable things that are much easier to express in C++ than Rust, owing to C++ being a significantly more expressive language. Rust also doesn't make it easy to write software where ownership is intrinsically ambiguous and must be algorithmically resolved at runtime without wrapping the object, a common case e.g. for high-performance storage.

I would agree that everything is harder in C, though.
