I don't know about this. I don't think I should spend most of my time learning completely new tools. If people spend most of their time learning tools, that encourages tools which are easy to learn but lack deep and powerful functionality. I think it's fine, and even good, for tools to require focused learning to understand, and in exchange have a worldview and tool use that is really powerful. Like Emacs or vim or Excel, for example.
