How does the coming crash, when all the old people retire and I quote " All investments and savings will disapear and there will be plenty of old starving people dying like flies and begging foreigners to come and take over". How does this crash make the nuke plants, water treatment plants, natural gas pipelines and all the other infrastructure suddenly evaporate?
Because all those things have to maintened by the real people capable of doing work. Assuming that they will be automatized, they will not "suddenly evaporate". They will just break down gradually.
