I've used Sublime Text; it's not a bad editor; but compared to using Vim, it’s like being in quicksand.

Sublime Text should be more modern and useful than Vim, an editor with roots going back to the 1970's. As the article describes:

>Vi is fundamentally built on command composability. It favors small, general-purpose commands that can be combined with objects to compose larger commands. By contrast, Emacs and its philosophical descendants (including Sublime Text and Atom) use monolithic, special-purpose commands.

You can't add enough special purpose commands to something like Sublime Text and have it be useable to approach what one can do with Vi/Vim and its composability.

Finally, Vim 8.0 was released just last year (2016), so it's not like it's not being updated with new features.

Last thing from the aforementioned article:

>A new, shiny, modern editor could one-up Vim by fixing some (or hopefully all) of these issues. But before an editor can replace Vim, it needs to learn everything that 1976 has to teach — not just the lesson of Emacs, but also the lesson of vi.
