When the capitalists have deployed AI to do the managerial jobs, and robots to do the physical jobs, when services are provided by chat bots & 'caring machines', when workers no longer have any work to do... who exactly will buy the good the capitalists have in their warehouses & the services they are offering?
It may not happen in my life time but a dystopia of no effective demand & an unemployed population doesn't look like the sunny uplands of capitalism, it looks like its end!
