As much as I agree with the premise of liberation from toil, I don't think the author presents a compelling argument as to how you get from "most of the capital sits in the hands of a small group of oligarchs" today to "the fruits of AI productivity are broadly shared". Historically, capital-heavy innovations have made a small group of people very rich. I have zero doubt without very decisive action, the default is absolutely a "whoever has capital at time of singularity has capital forever".
