Vim is well emulated in Emacs, but it really shouldn’t be thought of in the same category.

Emacs is more of an unbelivably editable lisp system to streamline your computing that happens to have a decent default editor.

It can support vertical and short length videos, but doesn’t really treat them much differently than other videos. Jared White did this shorts style test almost a year ago https://makertube.net/w/9v73BrPNvW7wYqRJLVbPkw . While Loops is more designed for that format, Peertube can definitely support them too.

Base Emacs 29 will do a lot for you in those areas, especially with rust-ts-mode (Treesitter powered Rust mode), Markdown mode, Company (a completion tool), and Eglot (lsp server client). I also recommend adding Which-Key to help figure out the bindings in different modes. Built-in eshell is great for scripting / terminal needs.

For a kickstarter config, System Crafters’ is pretty nice and will mostly keep you to built ins with good documentation of why they chose things. https://github.com/SystemCrafters/crafted-emacs/ and they have a Rust example config using their modules in their examples.

Doom Emacs and Space Emacs are cool too to show some possibilities and get a full featured ide earlier, but there those setups due add their own learning steps.
