Andrew Kelley quit his job in 2018 to build a programming language. Eight years later, Zig powers Ghostty, TigerBeetle and Uber’s cross-compilation. It’s top 5 most admired on Stack Overflow. There’s just one thing missing: 1.0. Andrew Kelley explains why.
Vitaly talked to Andrew about:
- Why Zig has no 1.0 after a decade, and why that’s deliberate
- Why Zig left GitHub
- Why Zig banned AI from Zig
- What makes Zig better than C (and why every other C replacement failed)
- Andrew’s take on Open Source
It’s a long interview, but I found it very interesting and worth it.



It’s definitely better than C but I’m still unsold on the memory unsafety. Especially after the supposed answer to Bun’s memory bugs was “just never dynamically allocate”.
comptimeis definitely neat and there are some other nice features but tbh it seems like the only true advantage it has over Rust is compile time, and only for incremental compilation. Is that enough? I would say probably not.The answer to Bun’s memory bugs was to follow a style guide. Not allocating dynamically stems from the style guide used by a mission-critical financial transactions database. Bun didn’t have to use that style guide, and honestly it would have been overkill. They could have easily adopted a different one, modified one to suit their needs, or made their own.
In general, I agree that Rust does a far better job at preventing these kinds of bugs than a style guide does, but Bun didn’t even try one and decided instead to ask Claude to rewrite it in Rust.
To be honest I don’t see how a “style guide” is going to help. C++ has had all sorts of guidelines and style guides for decades and it helps a bit but… not really.
What does the Zig compiler’s own style guide say about avoiding memory errors? As far as I can see nothing?
Is this style guide not a style guide?
It does help though without requiring a complete rewrite in another language, which is prone to causing entirely new issues and reintroducing old, fixed ones.
Like I said, Rust does a much better job at avoiding these. “Claude rewrite this in Rust” doesn’t give you those benefits for free.
It’s a start, but doesn’t say much about methods to avoid the memory issues that they supposedly had issues with. If they intended to actually use it, maybe it’d have more than 7 commits from 8 months ago. Maybe they would have updated it with patterns to prevent new bugs in the future based on the bugs they ran into. That didn’t happen, though.
