I did not read this whole article. The title caught my eye and I was curious what they thought, but it turns out the whole thing is predicated on advancements in AI that do not seem to me to be guaranteed.
But beyond that, I don't understand why the such advancements would only be useful to those in power. It's probably true that more powerful tools will magnify the power of those who already have power, but I'd imagine advanced AI systems as they describe in this paper would also be a pretty powerful force for destabilizing authorities.
All in all, I think marvel comics may be a better predictor of the future than the folks who wrote this paper.
