Have you come across any articles or literature indicating what the rich and powerful have in mind for the increasing numbers of economically useless people?
Since money is simply a unit of accounting and can be created out of thin air (banks do it all the time when they generate a loan, most of which is NOT drawn from existing reserves) it seems plausible the government could similarly issue money into existence and hand it out to everyone to spend as they see fit. If rich people can accrue millions in interest simply by breathing, the rest of us should be able to cadge a grand or so every month in a similar manner.
As for what to do with our time, perhaps release from the imperative to produce will allow us to once again tend our (metaphorical) looms.

You can drive yourself and others mad with predictions on this that and the other but in the end fate has a way of taking her own time, in her own way. A sudden unexpected climate change either to extreme cold or extreme hot, could alter things considerably , a virus that reduced the world population by two thirds or more ( something that is very possible although not fashionable to mention ) would catapult the entire planet into chaos, and of course let us not forget the possibility of space travel taking people to new homes on other planets. Of one thing you can be sure, nothing will happen before its time but you have my permission to frighten yourselves to death contemplating all the possibilities.
