Let’s not beat down the A380. It is an amazing airplane and, as long as you don’t fly it into turbulence, you’ll be fine. Of course if you do fly it into turbulence, those little, puny, cracks might just grow...

The 747 is a known quantity, the engineers have known for over 40 years what the 747 stresses are, and the wings were tested even way back in 1968 with a static test plane by bending the wings until they broke and said that the wings of the 747 can handle more than what it will ever see in service.
Will Airbus get this problem fixed in the short term ? maybe, maybe not, if it's a wing spar, or wing root, or wing box, then they got major problems.
