I'm glad to see this discussion getting started. The points raised in this thread so far are well stated, and this is an important issue to talk openly about at a core level.

I'm the lead developer of the visual editor, so I've been involved in this space for some time now. I've heard the following argument many times before - and I would like to respond to it in particular:

First of all, if editors can't master even the simplest wiki markup

an editor? Basic Wikipedia markup contains a dozen of tokens, if not
less.
On the contrary, those who've mastered the basics have passed the
first and unobtrusive"editorial filter".

I think it fails to take into account a few things:
  1. It's getting harder to edit - The relative difficulty of contributing to Wikipedia compared to other ways to publish content online has changed over time because other sites have made usability improvements
  2. We've done our research - There are many ways to improve usability, the decision to move towards a visual editor was based on usability research conducted in a lab and through remote user testing
  3. The status quo is failing us - We know that fewer people are editing Wikipedia than they used to, and reversing this trend has become a  priority for the Wikimedia Foundation
I would also like to offer some perspective from "the visual editor team".
I hope this effectively illustrates an alternative perspective on this subject. This is a very hard problem, and any course of action will involve some level of risk. We are trying our best to manage this risk, mostly by conducting a great deal of research and development.
