Technology has advanced greatly and the rate of innovation has been accelerating (although I would say that this rate is approaching a plateau).
It has certainly advanced to a degree that it is steadily replacing the human element at the work place. As humans become redundant in an increasing number of tasks so too will society be increasingly at pressure to adjust to current circumstances.
Work continues to flow. Jobs are created. Economies expand. Where these fail - austerity measures and unemployment take hold. Humans are addicted to work because it is what most are raised to believe - Work hard so that you can work better and become materially gifted (a paraphrase, admittedly).
But as technology continues to advance, work shall become increasingly a sentimental process - an act of perpetuation because the purpose of life has been so closely tied to work.
A humanity ill-adjusted for a non-work-based life purpose would suffer in the same way that a large portion of people suffer post-pension stresses as their health, physical, emotional and mental, declines.
Work is virtual in two circumstances. It is virtual when it is a process not directly related to the task at hand (for example - cleaning or maintaining one's tools between uses). It is also virtual when it is non-essential to the needs of society or self (anything from parking attendants to and beyond marketing managerial positions).
What if technology were to reach levels whereby it could completely take on essential work processes, leaving only some virtual work processes for humans to handle. It would be possible for humans to continue performing the tasks overtaken but perhaps humanity would be set to adjust to the new reality and embrace the consequences.
