If the master thinks that the human race has reached the absolute pinnacle of human/machine interfacing for text editing after just a few short decades of trying then he needs to go away and have a little sit down and a think about where he went wrong in life.
Nah man, you're not enlightened. He's not saying don't build a new editor, just that you had better think long and hard before you decide to foist another learning curve on the world, and act like you're doing it a favor.
Nobody foists a text editor on anybody, they live or die on their merits as a text editor. And besides, where would the world be know without people trying to make things better? The master's wisdom is weak in this case! I strike him on the side of his head! Slap!
