Boeing is an aircraft manufacturer - they either make a profit or go out of business. The 747 is a cash machine and the 747-8 is as modern as any commercial aircraft flying.
Airbust is a socialist program to provide employment - doesn't matter if they make money or not, and they won't make money on the A380.
Plus, when the last A380 is flown to the boneyard, the aircrew will fly back home on a 747.
Sounds like wishful thinking ... Did you know that Airbus has orders for 244 of the A380-800 and have delivered 44 of them to date? Source
If history tells us anything, ANY company that milks a cash cow, dies a horrible death as soon as the cash cow dies. And that appears to be what Boeing is doing. They have a ~40 yr old design, that has been modernized - but is essentially a 40 yr old design; competing against aggressive companies like Airbus and CRJ. Boeing is losing contracts, and unless they can innovate - they are going to go the way of McDonnel Douglas, Lockheed and other aircraft manufacturers.
