It just goes to show; no matter how cool and trendy a language is... it still relies on good ol' busted up / unsafe C.
FFI can only go so far; even thin bindings will require development time which adds costs and detracts from actually solving your clients problem. Which is generally why C is still so popular and will easily outlive Dart, Go, Python, Swift, etc. Possibly the only hope we have at getting away from C is "C-based" languages like Objective-C and C++. All these other languages are going the wrong way.
