What does Emacs’ learning curve (actually) look like?
Some time ago, someone gave a graph showing how learning curves look different for different editors:

Assuming the horizontal axes is the experience with the tool, and vertical axes the retained information, what I can’t understand about the above graph is how can the curve for Emacs curve backward as your experience should always increase?!
It’s a good joke, with some definite truth to it.
I always assumed the author meant it as an indication that the more you learn about Emacs, the more possibilities for further learning open up to you. Hence the infinite spiral.
Or to put it another way, the more you know, the more you realise what you don’t know 🙂
