I can't say I personally (or even professionally) need a systems language of the non-GC variety. The development speed vs execution speed differences don't pay off. At the same time, I'm very interested in how these lower level languages are becoming more and more generally usable. Rust seems to be leading at the moment and I find Zig very promising. My long-term bet would be for Jai or extracting "Within C++, there is a much smaller and cleaner language struggling to get out".
