A lot of half-truth in these postings.
Boeing had no interest in building a 747-competitor because it had already one. Boeing was able to subsidise its smaller models with the profit of the monopoly-747. It's not the market that is missing, its the missing opportunity for Boeing. So even if Airbus never makes profit with the A380, it still makes more money by selling more of the other models.
Having said this I do agree that the flaws in Airbus' organization and production is embarassing and unprofitable. But not the end of Airbus. People with a longer memory of just a few years know that nearly every new aircraft concept had delays (if I'm correct every single aircraft except the 777).
