Looks promising. First neovim and now this. Even if it doesn't replace emacs (which it won't) if it can enrich the community and maybe bring more users while fixing archaic code bases of hard to find errors and UBs then it is still a win. Neovim pushed vim (Vim suddenly became more active around the time neovim gained traction atleast according to github graphs and releases). So I hope this project brings new life to the core C code in emacs and fixes the problems that it never had (according to the core dev knowledge). When I tried emacs I found it to be a bit like atom at startups. Couldn't get into the keybindings coming from vim.
If it gets faster, I might give it a try again (in evil ofcourse, gotta have them keys).
