But why?

It works and I have control over my CPU instructions if I want it :), because it's worked for 40+ years in the same way over and over again, and is available on every machine and developer and ABI layers, the same way it's always done. You can save your breath on zig I'm very aware of it's capabilities and I'm not against it, right tool for the right job, but for the reasons stated above, I think C is the largest hammer in the tool belt and should continue to be used when necessary.
