Should a covid-19 miracle cure appear then perhaps the A380 may live for a few more years yet.
In our microcosm called Australia where unrestricted international travel has now been banned for over a year, Australians have taken to travelling in their own backyards. This has sent prices for used cars, new cars, car-hire, accomodation, entry-tickets, etc, etc through the roof because of the sudden huge surge in demand. When the ban on international travel is lifted I would imagine a similar surge in demand would occur in air travel for a couple of holiday seasons at least.
