The modern paradigm of running npm/brew/composer/webpack/whatever gimcrack tool that gets shoehorned into the build process has led a lot of people to the VSCode-ish side of things that make integrating these things easy. emacs tends to look like a well-appointed workshop with lots of good, sharp tools and a stack of raw lumber, whereas VSCode looks like a finished Chesterfield. It takes a certain sort of person to prefer the workshop over the finished piece, and I'm not sure you could ever change that.

Is a little to far into scify land.
First it requires software to no longer be text based, and then it requires virtually all software to switch to this non-text based solution.
In that world a single user can keep Emacs up to date and compatible by asking our AI overlords to do it.
