Repeat after me: Rust is not just memory safe C++!

Memory safety is a really big reason to use Rust, but it is very very far from the only reason. Even if Fil-C was magically zero-overhead (that is basically what CHERI is), I would still rather use Rust.

Rust has so many advantages over something like Fil-C it's hard to list them. I think Fil-C is a great project but it's only really relevant if you have no choice but to use C. If you can use Rust you also get:

* Compile time memory safety (Fil-C / CHERI are run-time).

* A modern functional-style type system (helps prevent logic bugs).

* Tree ownership (helps prevent logic bugs)

* Sane toolchain (helps prevent hair loss).

* Easy dependencies.

* Vastly more things checked at compile time.

Also I find it amusing how this post claimed it wasn't about Rust and then spent the whole time talking about it.

Rust is great. I don't think that really needs to be debated any more.
