Rust is 8 years since 1.0, Zig hasn't even reached 1.0 yet.

If you compare like for like, Rust started development 17 years ago, as did Golang. Though Rust spent longer in the research project phase.

TBF, when a 1.0 is released doesn't mean it's viable right way for things like this. It takes a certain level of market adoption and ecosystem buy-in first.

Also, Zig still isn't 1.0 so if we're measuring languages from when they first became public, I believe those others in your list are much older as well.

Sure, but when these languages first came out they didn't have anything like the library ecosystems they have today. In 2023, you can add a JavaScript or CSS parser to your app with a single line of code. Back then you'd have had to write your own.
