If you are thinking of learning a power tool, listen to Drew Neil’s advice. The article focuses on vim in comparison with other text editors, but this advice is applicable to all power tools. A typical quality of power tools is the difficult learning curve. Many try to bypass that by making it behave like something they already know. This makes it familiar in the beginning, but dangerous as well.
Every customization you make will come with edge cases and its own quirks. If you understand a tool and then customize it, you will be able to find out in cases it behaves weirdly. Without understanding the tool, these customizations can betray you, sometimes at urgent and important times. Also, if you think about it, why learn a new tool which you will customize and disguise as your existing tool? These customizations are cool to demonstrate its flexibility, but they will get in your way if you are trying to learn it. If you are thinking that this new tool will help you be more efficient, it can do that only by being different from your current tool, not by being its clone.
Replace vim with Linux or Emacs or a new programming language or your new chainsaw!
