The features of this thing all sound decent enough, but there's no source code, and it doesn't run on Windows, and it doesn't run on macOS, and scripting is "coming soon" - I wonder if that scripting will end up even half as good as Emacs's programmability. I bet it won't.
I have been here before. And that is exactly why I continue to use Emacs, even though it is a bit weird. I bet I will still be using Emacs in 2035, and I bet this thing will be long dead.
(I bet based on the odds. Time will tell.)
