Hmmm. I'm not sure I agree with this. That's like saying that people use a screw driver to screw in a nail because it's a much lower investment and not everyone has the energy to use a drill.
The premise of the article is that the VIM is better enough than alternatives that it's worth the learning curve. Just like a drill is better enough than a screwdriver to learn ho to use it. If you want to contest that, that's a different discussion.
If your argument is, "some people don't have the energy to use the best tool for the job"... idk how to respond to that.
