Road transportation accounts for ~50% of oil consumption. In 20 years most cars may be electric. And if renewables continue growing such that oil consumption isn't simply shifted to power plants, the fuel inefficiency of the A380 may matter much less. Also, the shift to point-to-point can only grow so much before the fuel efficiencies of the 787 and A350 come into equilibrium with the density of the A380. Moreover, most of the world continues to flock to mega cities. As cities expand airport usage increases while simultaneously making it more costly to expand or build airports. But 20 years, let alone 40 years, is a long ways out; who knows what will transpire. That said, the 777 is 25 years old and still dominating. At 30 and 35 years it still may be dominating even as the 777X slowly replaces it. A 30-year-old A380 may still be no less relevant, if not more relevant, than today.
