The fallacy here is to assume that, because this is what have happened before, it will always happen in the future. Yes, farming got efficient with tractors, allowing farmers to move to the cities to fill jobs in factories that was starting up at the dawn of the mass production and industrial revolution. But that does not mean that all future resources (i.e. humans) being freed due to automation, tech development will have new jobs to move to. That there are jobs suitable for humans created. That humans are needed as part of production of goods, services, content etc. Also I would love to see a reference to why progress rely on creative destruction. Please provide pointers.
