The blog post is from a team that builds a library for creating rich text mode applications in the terminal. The examples include a file manager, a diff tool, a floating gutter, dropdown autocomplete, animated underlines, pixel editor, and so forth.
Your comment is confusing because emacs isn't a library for creating rich text mode applications. While it has some things that are somewhat similar to things mentioned in the blog, it's an editor at heart...not a rich text/tty library for other tools to leverage.
