I don't know if it's been given a name, but this new wave of (usually Rust) shell tools that are great and seem obvious in retrospect (fzf, rg, etc) strongly feel like they're doing exactly right what Emacs has "failed badly" at.
edit: And now that I think about it, the "failure of Emacs" thing feels a lot not going the old "Unix way, do one thing and speak text" ideals?
