No one here, not even someone who is in their 70s or older, is about to experience what we're heading into.
Unless you were born circa AD 1750, you have only ever known a global economy that has grown with energy and mineral usage expanding to bring about the biggest population and wealth explosion in 10,000 years of recorded human history.
Now, the party is over. There will not be another doubling of the global economy. Literally cannot happen. From here on, the reduced output of cheap energy and the increasing cost that comes as it declines in output, will mark a degrowth economy that the world will try - and fail - to prop up.
The politicians and captains of industry either already know this, or they're ignorant and are going to throw everything at the predicament (not problem, those have solutions) of the end of growth. But all it will achieve is to waste more resources at a time when we should be cutting back and conserving them all.
Climate change is a spectre over our species and will be horrific. However, before any single nation falls fully to climate change, there will be many that follow Sri Lanka's path now, where that country is basically finding out what it means to slide back along the trajectory we just climbed up.
