I think I will use vim-classic and possibly contribute to it. Not because of AI, but because I actually want to use Vim over say something like Neovim* and I actually like vimscript, which imo didn't need the development of vim9script to improve it.

Regarding why not Neovim, I think it's because a large section of the community want to create more complex TUI elements or replicate GUI interfaces and make it more like VS Code. I use Vim for the "vim way" not because it's in a terminal or it's not bloated like some other editors.
