To be fair, Zig 10 years ago is drastically different language from Zig today.

Which is unfortunately a problem for AI trained on Zig, it makes some AI-assisted Zig coding more challenging, like Q&A and code-completion. It's sad that this glass-ceiling has been enacted for new languages and frameworks, not a deal-breaker at all, just that suddenly there's this penalty on time-to-deliver on anything Zig. But then... the same issue exists when hiring good programmers for lesser-known tech.

There'll probably be a strategy (AEO?) for this in the future for newcomers and the underrepresented, like endless examples posted by a sane AI to their docs and github for instance so it gets picked up by training sets or live, tool calling, web-searches.
