Ok, time to clarify a few things as my post title was a bit strong. It's obvious that a lot of people find meta boxes to be useful. I'm ok with that. What I'm saying in the article and I used the image of the conceptual interface to point out is that, I'd like to see the Post Specific meta boxes be merged into the post editor so they disappear. Removing all meta boxes is probably a bad idea but if I could merge the ones I use most into the editor, then we're on to something. That's why I'm such a fan of the conceptual editor because it does exactly that.

As someone else mentioned, it's also an iteration of the editor instead of something completely new. I think users would be more inclined to use it versus outright reject it. But who knows since no one likes change.

Also, I can't wait for the REST API because apparently, someone would be able to come up with an interface like this or something like it.
