Vim is one of the most successful open-source software programs of all time. It's been going strong for over two decades.

Neovim aims to replace it, but it is not a new generation of vim, it is a new and completely different project by different people, that may or may not succeed.

I wish them the best of luck, but it is by no means clear that Neovim will ever achieve close to the user base that vim has today.

There is a difference between neovim favoring lua, and vim still existing. Plus their official stance is that vimscript is a worthy language for it's job and support for it isn't going anywhere.

But when do we expect this to happen? Why would normal vim users change?

Just curious, do you use vim daily? Not asking to be a tool - genuinely curious if that's your opinion as a user or as an observer.
