I agree, the Airbus 380 was not designed adequately. Airbus rushed the project, made false promises, and now is paying the price for their mistakes.
If you take a look at the A380 flight deck, you'll notice that it’s not much different from other Airbus flight decks. It's the same blue design from the 80’s; they seem to be stuck with the original design of the original 320. On the other hand Boeing is moving forward, creating lighter aircraft, and designing helpful futuristic flight decks. Boeing is moving forward, while Airbus continues to stall back. I believe the A380 flight deck should have been more advanced, there was no need for a flight deck that resembles the A340 because the A380 looks nothing like the 340 and performs differently. Its different training altogether so in this case cockpit familiarity doesn’t help.
