Just a clarification: what you're saying is that most jobs aren't essential and can be computerized. That doesn't mean they're not worth something, or that people will be able to stay at home and just live in idleness.
What happens is that most jobs switch from agriculture & industry to the infamous "services"... most of us will be/are selling nonessential services (entertainment, leisure, nonessential medical services & care, advertising, etc..). Most of government is probably in the "nonessential" category.
Some % of the workforce will still work on R&D and essential services of course.
Having all the basics covered by a small percentage of the workforce doesn't mean the rest will have to work less.. on the contrary, the battle to divest people from their money will be fiercer than ever - more and better and more exotic services, more advertising, etc. It would be interesting to live in a post-scarcity society, but we're nowhere near there yet (and I'll be a bit Malthusian and say that we should curb the population growth a bit if we want to have what I consider to be a good standard of living in the future)
