A more constructive angle to this debate would be to compare HTML/CSS to other declarative UI frameworks such as those in QT and iOS and discuss what features need to be added or removed to make HTML/CSS more maintainable and less painful.
We all know the history of HTML and we're aware of the path it's evolution has taken.
Are you arguing that it's inherently unfixable and needs to be scrapped? I think you'd have a tough time arguing that point so why not move the debate forward instead of playing the curmudgeon?
