The problem is not necessarily to be fast for me (I know people who are very fast with the combo mouse / keyboard) but more if you like it. If you don't enjoy working with your tools, you'll have a lot of friction to do your work. I'm not sure everybody would like a development environment as I describe it, that's why I invite people to try Vim for example for a couple of week (I've some free articles on my blog about that) or i3, and see what they think about it. Exploring new possibilities is never bad. About learning the tools: I agree, but you can learn much more from some tools than others. I think of Vim as easy to learn, hard to master because there is so many stuff you can do with it. But I used Intellij IDEs as well for a long time, and I don't think it's hard to master, because there's not so much you can master, except maybe the keyboard shortcuts.
