I mean, it kinds seems inevitable to me. Books has become e-books. Cash is becoming digital transfers. China has done it. The west is mostly doing card-swipes. One day, that transition will be complete, and cash would be phased out.
What happens then? Think like the power outage in Spain recently. Some people had cash. But in 20-40 years. There might not even be any cash in existence. What then?
What if, instead of a few hours, its a few days? Or weeks?
I guess riots break out all around the world?
(Seriously, has none of the politicians ever thought about this? Where are the backups? Are we just going full “YOLO” on the reliance on the power grid?)
People will adjust. What happened on Portugal and Spain was caused by excessive centralization of the power grid, not by digitization. If somehow we can’t keep the centralized grid running anymore, we will break it down, and bear the extra costs for that.
Also, the sequence of a catastrophe is almost never a riot. Where do people get the idea of riots? People just go and do the right thing.
The technicians did.
You mean generators? Lots of people have those.
I would understand this question if you lived in 1925, but by 2025 you should know the answer already. Are you so blind about everything that needs electricity that you think disaster would come from the lack of money?
