Let's give the world a good 500 to 1000 years (Or longer for less-developed nations). Do you see machines completely replacing manual labor and working positions? As in, instead of there being miners, there would be excavation machines manipulated from afar? Instead of farmers driving large tractors, will there be large machines programmed to do it for the companies that own the farms?

And, if machines completely replace these working jobs, would this mean that the role of human beings would now only exist in intellectual or entertainment positions? For example, instead of working on farms or in mines, human beings would engineer and maintain the machines that work on the farms or in the mines.

I see this happening; the "working class" will gradually phase out. However, in order for society to remain healthy in this future, higher education may have to be completely socialized, so that it could be affordable for all (As while genetics may play a small role in determining whether or not a person is "blue-collar," education is the key; this would also mean that the general education requirements for society would be far more in-depth than the education requirements in the present day, as in, instead of being required for most jobs to complete high school, you would be required by most, if not all, jobs to complete college). Would this be the case or not? What are your thoughts on this?
