Here, I just did a quick test with claude.

1. "make a simple tcp echo server that uses rust"

compiles and runs - took a few seconds to generate.

2. "make a simple tcp echo server that uses zig"

result: compile error, took literal minutes of spinning and thinking to generate

response: "ziglang.org isn't in the allowed domains. Let me check if there's another way, or just verify the code compiles conceptually and present it clean."

/opt/homebrew/Cellar/zig/0.15.2/lib/zig/std/Io/Writer.zig:1200:9: error: ambiguous format string; specify {f} to call format method, or {any} to skip it @compileError("ambiguous format string; specify {f} to call format method, or {any} to skip it"); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3. "make a simple tcp echo server that uses zig 0.16"

result: compile error:

zig build-exe main.zig main.zig:30:21: error: no field named 'io' in struct 'process.Init.Minimal' const io = init.io; ^~

4. "make a simple tcp echo server that uses zig 0.15"

result: compile error

zig build-exe main.zig /nix/store/as1zlvrrwwh69ii56xg6yd7f6xyjx8mv-zig-0.15.2/lib/std/Io/Writer.zig:1200:9: error: ambiguous format string; specify {f} to call format method, or {any} to skip it @compileError("ambiguous format string; specify {f} to call format method, or {any} to skip it");

Rust took seconds and just works. Zig examples took minutes and don't work out of the box. The DX & velocity isn't even close.
