I don't know why anyone would write CLI tools in rust or zig. I/O is going to be your bottleneck way more often than GC, in fact I don't really get the GC hate outside of game dev, databases and other memory intensive applications. Why not use Go, Python, etc? People try to make a false dichotomy between memory safety vs. non-memory safety when really it's GC vs. no GC --- memory safety without it is going to be hard either way. More time should be spent on justifying to yourself why you shouldn't be using a GC, and less on which kind of GC-less language you use.

(If you go no GC "because it's fun" then there's no need for the post in the first place --- just use what's fun!)
