I think it would be fun for someone to write a short story / novel around a rogue AI emerging within the ecosystem created by "ownerless contracts and program execution" and "programmable free markets".

Imagine a programmer creating a genetic algorithm for crypto-trading. They enable to code to purchase new VMs to execute itself when it has a positive balance (on a cloud service that allows crypto / ownerless payments). The successful variants propagate to new VMs, the unsuccessful ones die off.

The code pays a certain percentage out to the creator's wallet.
