> You should ask, and answer, the question in reverse. What does neovim offer me, as a regular vim user?

Well, one of the goals of neovim was to make it easier for new people to contribute.

So, there's an obvious feature you might be overlooking: the project surviving past its creators passing.

Beyond that, async, lua, lsp and treesitter support are other things neovim brings to the table. I don't use vim much anymore, but I know that neovim incorporated them first. If vim did follow on some of those innovations, consider how long it might take for new vim maintainers to get to a point where Bram needed to be to keep up, without his guidance.

I wonder if there is a need for both vim and neovim in the future. Neovim was born out of wanting to do similar things to what the vim maintainers are considering.
