What will the world look like in 2078?
Put differently - how radically will the world be changed by the time Britain's Prince George, christened last week, turns 65 and possibly King George VII by then?
Peering along the life trajectory of the royal baby, Allianz Global Investors tries to figure out the answer in a recent three-part report.
Crystal ball gazing is fraught but Allianz observes that much of how the next 65 years will pan out depends on what the world does now.
Likely future shifts in geopolitics can be gleaned from current trends such as population growth, changing mobility habits, energy use and climate change.
The report predicts that by the time little Prince George turns 65, he will be considered more middle-aged than senior.
The United Nations estimates that by 2078, the number of centenarians will rise to 11.3 million from 410,000 today.
Birth rates are expected to fall but with longevity, world population will rise.
When George begins work as king, it will no longer be unusual for people over 65 to be working full-time.
An ageing society calls for a recalibration of many things, including city and workforce planning.
"In this future world, our concept of working and pensions will be completely obsolete," says Mr Volker Deville, Allianz executive vice-president and co-organiser of the annual Berlin Demography Forum.
