> As for motivation... I wonder how many of the new editors are a "let's rewrite it in Rust" thing?
None? I mean, Helix and Kakoune are written in Rust, but they are not rewrites, they have very different goals than e.g. neovim.
They explore different concepts, workflows and ideas, and the choice of Rust as a language merely stems from the authors finding Rust to be a pleasant and appropriate language to explore their ideas
