Exactly. Both Blockchain and AI make the perfect combination for an efficient worldwide economy that's fair, secure, and transparent, most of all. AI would be responsible for the decision making of our daily lives, while Blockchain makes sure that everything is correct and free from fraud. Nearly everything we know and love today, would live within the Blockchain, from properties & assets, to personal and medical information. When put together with AI, new possibilities are opened like never, enabling a trustless society in the future.
Human intervention or arbitration would not be necessary, as everything will operate on its own. Machines would rely on micropayments to function and operate as intended. People would have control of their own money and lives, as central control would be reduced to a minimum. Everything would be governed by smart contracts living under the Blockchain, in par with AI, making the world free from corruption like it is right now. Such scenario would be similar to Terminator's Skynet, where AI takes control of the world in an unstoppable way (since it relies on millions of computers and devices worldwide). However, this process might take a couple of years from now before it becomes a reality. Just my thoughts
