The gains of technology are mostly captured by those with capital, not those with labor. Look at wage growth over the last few decades as well as productivity growth to have confirmation.
There’s no reason to believe given the current trend that benefits will be evenly distributed to the 99-97% of wage earners.
Right, but in this hypothetical future where "basically nobody have a job", would we still live in such a system? If so, where do the money come from if people don't work for it?
> it really leads one to wonder what kind of economic system(s) we'll have
It's not clear how a future economy works if nobody has a job. If nobody has a job, how do they acquire food, shelter, clothes, etc? And if people don't have money to buy "stuff" then what need is there for factories to produce "stuff", or stores to sell "stuff" and so on? So does economic output just drop to zero? Or near zero?
Of course there are proposals around UBI and what-not and maybe one or more of those is the answer (if all of this comes to pass in the first place). But it seems to me that there are still a lot of questions to answer.
