tikhonj jokingly suggests emacs but even as a vim user I fully agree. Like they say, the beauty of it is that the complexity draws from simpler foundations. It is written as an environment rather than just as a text editor. Being written that way lets it adapt to many different situations and is what has kept both vim and emacs alive and popular after all these years. There's a constant in software development: requirements change with time. The point of writing an environment is that you're able to adapt to these changes. So any time you write a tool that tool is built out of that environment. Anything short of that means the tool won't be able to adapt as time marches on.

I definitely agree that writing software like this is hard but I'm not sure if it is harder. It takes more work up front but I'd argue it takes less work in the long run. It's just that in the long run many efforts are distributed across different people and time. But hey, good flexible code also tends to be much easier to read and that's big short term benefit to anyone coming into a mature project.
