Agreed. A "job" fulfills these roles as well. The change we are heading towards will not diminish this. We all have to do something; to create meaning in life. None of that will change. The difference will be that what you do to create a fulfilling life will no longer be intertwined with the function of accessing the resources we all need to live.I think there is more to it than you list. Some people enjoy their jobs/vocation and wouldn't do anything else. Scientists and musicians, for example, probably see what they do as an integral component of themselves with no other considerations. I know that I was internally destined from almost birth to be a scientist, and becoming one had nothing to do with obtaining a job, contributing to humanity, supplying myself with necessities, or any of the things you list. Similarly, musicians may do it for sex, drugs, and rock and roll (or sex, drugs, and Bach), but they are internally destined to pursue it without other considerations, and would unlikely do anything else.
Entrepreneurs, inventors, poets, novelists, explorers - there are many examples of internally-driven "jobs" not defined so narrowly, and likely not replaceable outside of far future developments.
Think "retirement". Most people retire from a job. But most of us continue to lead fulfilling, engaging lives. Getting paid to do a task is not necessary to living a fruitful life.
