It is surely premature to post the obsequies for the A380. At worst, it was a little early, just as the 747 was early in its day.
Indeed, the 747 production collapsed from around 100/yr to about 20/yr, so the A380 has been managed much more prudently than its predecessor. Will the program make a decent profit? Not in the near future, but until the Chinese ramp up their 'C380' equivalent version, this is a uniquely capable aircraft that is attuned to a world of low cost travelers using a constrained airport infrastructure.
The A380 has another 20+ years of production life ahead of it, with no near term competitor.
