Same here, I don't have any use for Rust, and am perfectly fine with automatic resource management languages (regardless of the approach).

However, Rust has been quite successful making more developers think about less known type systems, besides affine types, there is also linear types, effects, dependent types, prof systems.

And we as industry aren't going to throw away the millions and millions of stuff that was written in C, C++ and less extent Objective-C, thus efforts like Fil-C are quite welcomed.

Now that suggests an idea: Objective-Fil-C !
