What it has achieved is making affine types something mainstream developers would care about.

That kind of is a bit load bearing. The differences are pretty huge. Plus, borrow checker is nowhere to be found. Cyclone is more C with a few tweaks (tagged unions, generics, regions, etc.).

		Borrow checking is basically a synonym for affine type system. The same outcome can be achieved via affine types, linear types, effects, dependent types, regions, proofs, among many other CS research in type systems. Which is why following Rust's success, plenty of managed languages are now going through the evolution step to combine automatic resource management with improved type systems. Taking the one that best approaches their current design.
