The most astonishing thing about technology is that it was to be expected that indeed it would end the need for people to work so much. By ending the need for some human labour, it would create opportunities to decrease working time. Most people in the 20th century that wrote about the future imagined a world like that, with less working time.
However, because of globalization, what we see is the decrease of the price of goods, not the increase of the wages or even a significant decrease of working time. On the contrary, since 2008, we are seeing a stabilization or even a small increase on the working time (and limitation of the rights of workers), also in many countries of the developed world (see about OECD counties:
https://stats.oecd.org/Index.aspx?DataSetCode=ANHRS; moreover, some of the small decrease of working time might be unwanted by the workers, but forced on them as part-time jobs with half wages).
The increase of productivity is going straight to the pockets of the capital owners and managers or to decrease the price of goods. Now, some CEOs say that their working force only cost them 10% of all their costs. They pay more in energy, raw materials, machines, renting places, etc.
Forget about technologic unemployment. Employers will put uneducated workers to work, for pennies, if necessary on small services, just to increase employers' happiness. They love to have an army of (sub paid) servants. Why have a robot as butler, it will give much more status to have an (almost) slave human.
