> if robots are that advanced that can do most of the jobs - the cost of goods will be close to zero.

No, the cost of goods will be the cost of the robots involved in production amortized over their production lifetime. Which, if robots are more productive than humans, will not be “near zero” from the point of view of any human without ownership of at least the number of robots needed to produce the goods that they wish to consume (whether that’s private ownership or their share of socially-owned robots). If there is essentially no demand for human labor, it will, instead, be near infinite from their perspective .

Sure... in 200 years. The trick is getting through the cultural/economic shifts required to get to that point without blowing up the earth in WW3.

No. You become worthless to the government and will be treated accordingly

I'm pretty sure if robots are capable of doing most jobs, the only ones left will be related to prostitution or fluid/tissue/organ donation.

Rich ppl doing something to undermine their status as „the better ones”?

This is not going to happen.

We all know a post-apocalyptic world is what awaits us.

More or less Elysium is the future if ppl will still behave the same way they do now.

And I doubt ppl will change in a span of 100 years.

There are still capital costs in producing the robots and infrastructure. So the costs of goods will be nonzero.

>government will product and distribute most of the things above and you mostly won't need any money

So basicially what you are saying is that a government monopoly will control everything?
