Vi is meant for old school and modern terminals. Ctrl+S or Ctrl+C had very particular purposes in software control flow. With Vi you can communicate via SSH on almost any unix file system. It's basically a universal editor that doesn't require a mouse or a lot of keys on a keyboard. You can get away with just a subset of the ASCII set.

So for one, it's kind of like having a backwards compatible piece of software that exists on almost any system you might need to remotely control via a keyboard with no GUI.

For two, once you do learn how to use Vi/Vim/Emacs, you'll be far faster at typing. It has several useful tricks for automating typing (faster copy/paste, copy/paste n-times, jump around lines/chars, go-to lines, search via Regex, etc.) which are particularly useful in a programming context.

Generally, it's worth a developer spending at least a day or a week typing only in Vi for programming. Yes, you'll be slow and clunky. But the moment you have to SSH into a server and make meaningful changes to a file, you'll be happy you spent the time.

Then again, I have no idea what the difference between vi, vim, emacs, and nano are, so roast away!

Lol. Git Gud, Noob.

Some people like vim the way it is. That's why they haven't re-invented it. If you want to use a more intuitive text editor, there are plenty available (such as nano or micro).They don't need to turn vim into a clone of something that already exists.

As for why it's still the default... It's the same reason why everybody uses QWERTY keyboards when Dvorak is clearly superior. People already know how to type with QWERTY and they don't want to take the time to re-learn with a new layout, change their workflows, etc.

It isn't universal, though. Garuda Linux defaults to micro. The web dev boot camp I was in didn't bring vim up at all! We only used nano! I think that was a disservice to the students, but the instructors must've thought that it would be too confusing.

Why would vim reinvent itself? Vim's functionality has been standard for years, and works as expected. You can always use nano or something similar instead, which is probably a lot more usable to someone who doesn't want to learn all the advanced functionality of vim or emacs

Is vi still the default? On Debian it sure isn't, nano is the default and has been for years, and I can only assume the debian derivatives have all followed suit. That'd already be most new installs taken care of.

If you find something that opens vi unexpectedly, double-check $EDITOR's value then file a bug report and tell them to follow $EDITOR.

As a ~20 year vim user, and by no means a proficient power user (any time I end up in recording mode, I just mash ESC repeatedly until this start behaving normally again.), I think it's just "it's easier for someone that doesn't know how to use it to learn, than it is for everyone that already knows how to use it to relearn".

Like the damn scroll options on laptop trackpads. Multitouch scroll down = scroll down. Then someone decided it needed to match the way phone scrolling works after smartphones became popular, so now there's lots of scroll down = scroll up software behavior. But the options are still there to behave neither way. If you don't like the vim commands, you're free to install something that behaves in a way that you expect. If you do like vim commands, install it and get the behavior that users have come to expect for the last 20+ years.

Because vim (and emacs too!) is a powerful editor that works purely on command line and most people who are experienced in the Unix world are generally familiar with it. There are plenty of easier editors to use, like nano, that are also widely distributed and you are free to change your default. Being really powerful but you kind of need to know what you're doing is basically unix's whole thing.

To ensure the Unix-like standard of maximum backwards compatibility. Vi (the original, before Vim) was made in an age where computer keyboards might not have had luxury features like arrow keys, but did have alphanumeric keys and minimally competent users. It has worked for almost half a century, so unless you're Microsoft, why would you change it?

Even today, many people prefer it because you don't have to move your hand far away from the home row while typing or navigating, and the modality gives the user a much greater toolkit (seriously, I just about nutted when I discovered d i "). Not having to rely on modifiers and the arrow keys also reduces the risk of the repeated stress injury known as Emacs pinky.

Nano is the default on Debian for more than a decade. Maybe two. I don't think vim is the default on any largely use distro now.

Are you actually asking why people use them?

I guess some people really like the features. Imo Micro/Nano are much easier to use than Vim

i mean.... skill issue 🤷

Why are these hard to understand editors still the default on most distros and flavors

I think nano is usually the default nowdays. Nano os pretty minimal and has it's keybinds always on display so you don't need to memorize them.

Why haven't they reinvented themselves with easier to understand shortcuts?

Nothing about vim and alternatives feels intuitive or easy to use

(Neo)vim doesn't need to reinvent itself to be more accessible, because it does what it does very well. I'm a web dev and have used vscode like anybody else for a long time. I decided to try neovim because vscode was performing badly, but kept me using it because of how good the developer experience is. Once you learned how to use it, there is just nothing better.

but when every other software with keyboard shortcuts agrees on certain easy to remember standards, I don't quite understand how software that goes against all of that hasn't been replaced or hasn't reinvented itself in newer versions

In a way, it has been replaced. Most people will use a user friendly IDE and ignore vim. The thing about vim is that it does things in a fundamentally different way than any other editor, so reinventing itself would mean loosing everything that makes it good, then you better off using something else.

Then again, I have no idea what the difference between vi, vim, emacs, and nano are

Nano is a simple, easy terminal text editor; vi, vim and neovim are three versions of the same quirky and hard, but very good text editor/IDE; emacs is a quirky, but kinda bad editor that has amazingly good extendability.
