The potential of AI may give us the opportunity to graduate to a post-capitalism, or to move to a sort of neo-capitalism, which is governed by different rules.

Capitalism thrives in the realm where there is a scarcity of resources, either physical or informational. Imagine breakthroughs in energy science such that the cost of energy drops to zero, which means the cost of physical resources declines precipitously. Ok so where is the capital now? Must we retain a model based on the premise of scarce physical capital?

you are imagining magic as a reason to dump all your money and future money into a casino. You might instead consider joining the catholic church? they already have a free energy god that gives everything you could ever want

the cost of energy is already ~0 and people dont want it, and refuse to participate in letting other people have free energy if it affects their view of their pasture.

unless you are building killer robits with the intention of doing some soviet or nazi styled purges of everyone that might get in the way, you arent gonna get this ai utopia
