a world where none of us worked, where we didn't "have to worry about contributing value" to the group, because everything was taken care of by machines.

Humans could never achieve this utopia en masse because there would still be a scarcity of "luxury" goods, creating tiers of society that can afford different levels of goods. Just because machines can allow same base level of minimal subsistence, there will always be competition among people for the finer things in life.

Nice Miley quote! Gen Z and their kids toys these days.
