I think eventually, in the distant future, technology will reach a point where all of our basic needs (food, water, clothing, etc) can be provided at such low cost/effort by automated processes that do not require human workers... Most of you people arguing about this frankly won't be alive to see any of this happen ...
It could happen in as little as 5 years if it were approached systematically. But it won't. Even so, unemployment will rise dramatically, as it has already been doing for the past decade or so. There is little to be gained by hiring a person. It's much easier and more efficient to just adapt your business model to do without workers. Employees who are clever enough to be useful are also a threat.
