First the Concorde, now the A380. The light is dimming as the Permanent Dark Age dawns. Once you've filled in the periodic table, life changing innovations peter out. My paternal grandfather was born in 1880 and died in 1967. Just consider how the world around him changed over that span of time.
- aircraft, and all that brings
- space travel
- medicines of nearly every description
- computers, initially analog then digital then semi-conductor
You can continue to fill in that list at your leisure. Nearly every 'innovation' since 1950, say, is merely an incremental (at decreasing rate) nudge to those items. While population heads toward 8 billion, water becomes scarce, and wealth concentrates.
Have a nice day.
