If by production-ready you mean you can forever avoid changing code you wrote 8 months ago, sure, pick something else.
To me production-ready means it can be trusted to power production workloads, has all tooling I need, and has a consistent long-term vision. Zig ticks all the boxes.
I did, and I immediately found this in the latest release: https://ziglang.org/download/0.16.0/release-notes.html#IO-as...
That seems like it would require changing a lot of code. Calling it "production ready" is dishonest at best
