I understand what you're saying, but I think it's just as applicable to anyone else. Clear communication through writing is tough so when we can avoid it we attempt to verbally communicate our ideas but sometimes even that isn't enough. Now imagine being able to share your feelings with someone instead. You have an idea for an app and you know in your head what the look and feel is like, but you can't really describe it or put it onto paper. Transfer your thoughts to another person and I imagine this process would be much easier.
Or imagine thinking through tasks instead of performing them physically. Say I have a few vim windows open and my code isn't working. I see a few potential spots where I'll want to log some data. Even if you're a keyboard shortcut guru in vim or any other editor, you still have to navigate to each of those lines and add the line of code. If my brain were hooked up to my computer, I could simply think or look at those few sections and suddenly my code is there. Just thinking about this gets me excited about how much more productive I could be as a developer.
Or maybe I'm just crazy :)
