heres a little experiment. watch an episode of how its made, and count the number of workers. you will not, depending on the episode, be able to use all your fingers counting workers. we are already quite atonomous as far as production goes. in some countries like china, it becomes economically viable to use men instead of machines, because laborers there are willing to take a job with a low wage, and the cost of hiring all the needed employees is less than the cost of the design, construction and maintenance of machines to do the same job. eventually a fully mechanized china will come into being as their economy continues to build. automation tech will continue to improve in the mean time, and the cost of automated factory equipment will drop. and this will lower the economic threshold of entry into automated production.
we have already seen this happen in the us. so a lot of the jobs are jobs handling first world problems, such as health care, information, banking, service, and sales. places where we want people in the loop. banking could be totally automated if it didnt need constant monitoring. nobody wants to pay a fortune on health care to go visit a robot doctor. service usually requires some troubleshooting, which has yet to be automated (and all attempts to do so fail horrifically). sales (and advertising) also panders to human nature and is not really something you can automate. the human interaction in information tech is mostly troubleshooting the systems we use, policing them, so it is mostly a maintenance job, a thing hard to automate. there are plenty of other jobs but the thing is they are very hard to automate. you kinda need to distance yourself from the notion of full automation, because no matter how precise your robots and decision making ais are, they will always need supervision and maintenance.
we will get to a point where society is still dependent on a handful of highly paid very highly skilled workers doing essential jobs, but where we will have a bunch of ballast jobs that dont really dont accomplish anything in particular, but are just used to give society something to do to keep them happy/occupied and to give them money to live on. you know the kinds of jobs politicians like to create. of course paying people to expend effort in accomplishing nothing is wasteful. so simply entitling everyone to a basic standard of living: food, shelter, basic medical, etc. where work grants you extra resources. one big problem in the us is that working a minimum wage job pretty much forfeits most government services. so making the transition from entitlement case to paid worker involves a decrease in your standard of living. its not just the employers its the landlords too. i had a situation once where despite being employed i couldn't afford the cheapest apartment in town, so i ended up moving (and havent had a job since, you might note that im not homeless and actually have faster internet, which wouldn't be possible if i still had that job).
so it might be better to consider something where some percentage (say 25% as an example) of the population are working essential jobs, the few jobs needed to keep an automated society running. these are the people who thrive in a work environment and wouldn't be happy just being idle. you would have people who do non essential jobs, stuff that enriches society but isnt essential, they would get paid grants to continue on with their works, this is where artists, musicians, designers, athletes, intellectuals, etc would thrive. everyone else has their basic human needs taken care of, but are not required to work. currency would only exist as a way to ration resources, everyone (even people who work) is granted a basic standard of living allowance. children also have an allowance paid to their parents for child rearing expenses. if you work an essential job you earn a larger ration of resources (more money) in addition to your basic allowance. if you want to contribute to society but need funding, you can apply for a grant to pay for it (much like how research is funded), you might also be supported by contributions from individuals (crowd funding). being a non contributing member of society would be tolerated, treating basic human needs as a civil right.
