Given the current dynamic developments the future Robotic Work Force is not fantasy but technology round the corner capable of replacing Human Labor, while capable of decision making controlled by AI without Human Supervision.
One prevailing answer kind of dodges the question, but it also seems like one of the most plausible outcomes. Maybe many jobs can't be automated in the first place. Several respondents canvassed by Pew believe that the need for human labor will persist because so many of our basic human qualities are hard to code. "Truth be told, computers are not very smart. All they are is giant calculators," game designer and author Celia Pearce told Pew. "They can do things that require logic, but logic is only one part of the human mind."
That question is still heavily under discussion in economy, philosphy and technology areas. There are those horror numbers circulating of 50% and more which typically do not include the actual phenomenom, which has to be expected: an actual shift in the working ladscape. Some occupations will be lost, some new will be added. The total number of jobs however, will stay stable according to recent numbers.
As an example, a recent EU study suggests that the use of industrial robots has no conclusive correlation to the rate of employment (some companies shring in personnel, some grow, some stay stable).
From a philisophical point of view, even if the number of jobs stays the same (or grows), there is the major issue of re-educating the workforce. This will be the real challenge.
