Not a particularly deep comment, but... matklad (the author) created, essentially, the entirety of the modern Rust developer experience. He is the original author and biggest contributor to both rust-analyzer and Intellij Rust. If someone this central to the Rust world has switched to writing Zig full time, and not for boring, pragmatic reasons either, a little seed of doubt about the long-term stability of Rust as a professional community begins to grow in my heart.
Grayson Hoare who created Rust has been working on Swift language in the last few years at Apple. People change jobs, there is nothing wrong with that. Rust is a community driven project, and the community will keep building. IntelliJ Rust plugin has not stopped evolving since matklad left. matklad may found a new interesting project that happened to be using zig. He didn't say he left Rust community
The post is about how the languages serve different purposes, and he just happens to be working on a project now that he believes benefits more from Zig. Nowhere does he make broad-strokes statements about Rust's (or Zig's) fate
