Everyone's seems a bit worried about the collapse of capitalism and the ensuing apocolypse. I think it could be a good thing in reality, because it will cause us to become self contained again for a while.
Take Cuba for example. They had their own apocolypse when the communist revolution caused them to be isolated from the rest of the world. This in turn caused them to become self contained quite literally with import/export bans put upon them. In theory, and practise, freezing them in time. I went to Cuba a fair few years ago and you get a very real sense of just how frozen in time they are. The fact that all the cars are old American Cadilacs for example, the trade embargos put a stop to many further automobile updates so they just carried on driving what they had. But 50 years later those same cars are still moving, because they have no other choice than to keep them moving.
And take for example my boats engine. It's 25 years old but it still keeps my boat moving. As Steve my engineer says "they're good old girls if you keep them happy".
So rather than the world coming to an end. We might just learn to live with what we've got for a bit longer. And get self contained.
