The article says “and before too long everyone is complaining and saying they should be going back to WYSIWYG tools” I wonder what’s wrong with WYSIWYG tools? Personally, I use MS Word all the time. It works very well for me and for various people I interact with (clients, colleagues, bosses, subordinates, friends, family, etc.), for decades already.
