Marx thought that because machines (or robots) can produce lot more than humans and more effciently, a capitalist would replace little by little all humans workers by robots, with the benefits generated by the gain of productivity, for making more money and win the price competition... So the final society will have production only made by robots. It was partially true because he made the theory that these machines, well designed, cost less than hires hundreds humans with social rights, but he didn't expect that instead of replacing human by machines, we have found cheaper human work in China, or India for example, which is less efficient but cheaper at a large scale, when machines were too expaensive to invent or to maintain. New slave humans have replaced old slave humans protected now by social rights, and investments have been made to delocalisation not robotisation.
Neo-marxists believe that the society is not as Marx describe it as always a fight against classes, oppressed or exploited people against oppressor or exploitant people, but is divided in 3 strates. The INNOVATORS, the REPETITORS and the PARASITES.
Innovators are people which make the world move forward by their everyday work. Researchers, scientists, entrepreneurs, engineers, artists...
Repetitors are people which will not make the world move forward and change by their everyday work. These people are honorable, because they make repetitive stuff everyday to make the society run. It is your bus driver, your cloth seller, the nurse, the waiter at your restaurant etc...
So the innovators work depends exclusively of repetitors work. If nos buses, no farmers, the society falls down (see the Maslow pyramid of needs) and all the philosophers will come back to farm for eating. A funny question is : at which level of productity does we enable the apperance of a philosopher? It will be only when we'll have enough productivity to give resources to innovators just to innovate. Even be an entrepreneur ! If the repetitors were not there, you will not try to make your company. Think to all these repetitors thaht enable you to run your compaany, have employees coming at work, eating etc...
And parasites are people which slows the change, defined often by the cut of money they take of investment that make the workd change (Banks, even investors asking for dividends)
So they think that repetitors need to be and will be replaced by robots. Making repetitive things has no interest for humans, right? Humans are not work or energy like in Matrix...
Humans has to stay innovators, making the world move forward, exploiting always with more productivity the resources the earth provide and always try to better understand our world, with science, with art, with code.
Loking forward to see the robots coming in our everyday's life, enabling us to be really humans.
