Does wealth continue to be a coherent concept once very few have all of it? I don't think it's been tried.

Also, since markets are fundamentally neural networks (with prices as action potentials) it seems like an improved understanding of how to manipulate neural networks would coincide with a change in how we practice markets.

I suspect it'll come down to whether they can use markets to dispense with us faster than we can dispense with the use of markets amongst ourselves. Neither is an outcome that has much precedent because both would've seemed impossible pre-AI.
