Ask HN: Why programmers should use Vim?

In a lot of articles, video tutorials and books I see that programmers use VIM instead of a better editor like Sublime Text or something. I'm a programmer. I build apps with NodeJs, JavaScript, CSS and Python and I feel really better when I use Sublime Text because it's visual, I can use the mouse cursor for moving between tabs or copy or paste codes, then WHY should I use VIM? I mean is there any secret behind VIM that I (and maybe many other programmers) don't know?
