I’ve never understood this perspective. Companies only make money when there are billions of customers. Are you imagining a total-monopoly scenario where zero humans have any income/wealth and there are only AI companies selling/mining/etc to each other, fully on their own? In such an extreme scenario, clearly the world’s governments would nationalize these entities. I think the only realistic scenario in which the future is not markedly better for every single human is if some rogue AI system decides to exterminate us, which I find to be increasingly unlikely as safety improvements are made (like the paper released today).
As for the wealth disparity between rich and poor countries, it’s hard to know how politics will handle this one, but it’s unlikely that poor countries won’t also be drastically richer as the cost of basic living drops to basically zero. Imagine the cost of food, energy, etc in an ASI world. Today’s luxuries will surely be considered human rights necessities in the near future.
