Why I have to start studying about "vi" at this age ?

I think that.

I don't want to study new things anymore.

- The control network is "EtherCAT"

- Linux hardware is "Raspberry Pi", the distribution is "Ubuntu"

- I still think that Windows95 is enough for me, however I have to get on Windows10

- Basic language is "C / C ++", script is "python"

-And the editor is "emacs"

With these, I will end my life.

Why am I studying "vi" now?

The reason is that when I input

>sudo apt install emacs

It takes more than 15 minutes to download a huge amount of new files, and it also affects other modules, and I have to add

>sudo apt-get update

>sudo apt-get upgrade

As a result, I'm scared that the development system itself will stop working.

I'm not familiar with the history of "vi", however when I started using the computer, there was no OS without "vi" except Windows.

Even though it is such a popular editor, "vi" is not well known. Because it is difficult to use for beginners and easy to use for experts.

Well, once you try it, you will understand well what I say .

A young person in the software industry will soon learn "vi" because you don't have to face same like me.

It's quite difficult to start using "vi" at this age
