> why should a project maintainer spend time reviewing and discussing that PR as opposed to firing up their own LLM to solve the same problem?
perhaps that's what the maintainers should be doing after all. it still takes time and tokens, though; neither is free.
I'd personally rather have the maintainers spend the time writing as much docs and specs as possible so the future LLMs have strong guardrails. zig's policy will be completely outdated in a couple years, for better or worse. someone will take bun's fork, add a codegen improvement here, add a linker improvement there and suddenly you'll have a better, faster zig outside of zig.
If it gets outdated they can review their policy. Right now it is sensible. We're at early ages of this type of AI and we don't know what the end game will be.
Someone forking it and makeing it better with AI is a possibility. If that happens will know it was better for the project for the maintainers to just review the code. If that happens, they can probably become maintainers in the fork. Or maybe they don't like that work and could just go do something else
Zig strives to avoid numerous pitfalls, and I admire that.
Let's take a look at some of them:
1. Project control – if a LARGE company implements thousands of lines created by LLMs day after day – who is ultimately responsible for the project's progress? "You accept hundreds of PRs, so why not this one?"
And one more thing: will you be able to change the code yourself, or will you be forced to use LLMs? What if one of the "AI companies" implements a strict policy preventing "other tools that XXX" from editing the codebase?
2. Ownership. If most of the code was taken by an external company from their LLM, what about ownership of the code? The authors of Zig, the company, the authors of the original code, stolen by LLMs?
3. Liability. In the near future, a court may rule that LLMs are unethical and should not recombine code without the owners' prior consent. Who is responsible for damages and for removing the "stolen" code? The owners of Zig, the company that creates pull requests, or the authors of LLM programs?
4a. Vision. Creating and maintaining a large code base is very difficult – because without a broad perspective, vision, and the ability to predict and shape the future – code can devolve into an ugly mess of ad hoc fixes. We see this repeatedly when developers conclude, "This is unsustainable; the current code base prevents us from implementing the correct way to do things."
LLM programs cannot meet these requirements.
4b. There's another aspect – programming languages particularly suffer from a lack of vision or discipline. There are many factors that must be planned with appropriate capacity, vision, and rigor: the language itself should be modeled in a way that doesn't prevent correct implementation of behaviors. The standard library must be fast, concise, and stable. The compiler itself must be able to create code quickly and repeatably.
Users hate changes in a language – so if a language changes frequently, it is met with harsh criticism. Users hate incompatibility. Users hate technical debt and forced compatibility. Yes, there are conflicting requirements. The author of Zig understood this perfectly, having already gone through it himself (see, for example, "I/O Redesign").
This balance, in all aspects, is the pillar of human creativity.
To be honest, I'm not a huge fan of Zig because I dislike the tight syntax: too many periods and curly braces, which is why I prefer Odin. But I have a lot of affection and respect for Zig and its authors.
