I explored Zed on macOS when it was posted here previously, and my impression was that it was a fast and fully-featured editor.

However, it's not as ubiquitous on *nix systems as editors such as vi/vim. And for those of us who work with various infrastructures and deployment constraints, it's much easier to focus our efforts on an editor that is also ubiquitous. And vi/vim fits that mould.

In other words, while Zed is a vi-able alternative, I doubt most vi/vim users will switch to it exclusively.
