I'm afraid you have it exactly backwards. The problem isn't that it doesn't work -- the problem is that it does work. And to the extent that it isn't perfect, well, it's still improving all the time. You cited a 3-year-old article reporting on data from up to eleven(!) years ago -- an eternity in this field. Not even worth reading at this point.
