I have not combined AI and blockchain very much in my thinking until now... thanks for the brain exercise. If you look at cryptocurrencies like IOTA for example, they are designed to be a means for machines to pay each other micro-transactions. It would obviously only be relevant for machines to be paying each other in an automated (human free) system. This is assuming some intelligence among machines, or brilliant intelligence among the humans who set up the system. This is just one example of crypto and AI melding that I can think of. If we take this step a bit further, we have machines involved in automated processes where there is an economy among these automated processes. This is already world changing.
If you were a part of setting up the automation, or are on one end of the business or the other... there is income being generated where human hands need not go any longer. This could very easily increase the disparity between the haves (who now have machines making them money) and the have-nots (who now have machines that have replaced them and their source of income).

This will need to change the current social structure, as a large majority of people will have been rendered useless. The systems will not be able to continue to operate on the concept that every person must have a useful function in society. There just will not be enough functions for everyone. This was always more about power and control than over the creation of a perfectly functioning economy where everyone has a place. This pretense can no longer exist. This is why I see the rise of universal basic income being thrown out into debates and on talk radio etc. It is not a coincidence or a revolution... it is a means of preparing us for the next system where humans will not be at the center of all that needs to be done. The power structure will remain, the haves will continue to have. They will be forced to provide for the basic needs (and no more) of the have nots.

The utopian world that our parents believed in where the machines would make us need to work less was just a clever marketing scheme to sell machines. The AI revolution will be no different if the people in control can keep it. They will sell us on basic income and AI and keep their hands on the control. If we as a people are to break free from this system of control, governments, economic power, banks etc... blockchain technology may play a part in removing banks and governments, but the money held by those in power will transfer that power to the new dominant currency. Government was always under the thumb of the money, and that will likely follow suit in the new dominant currency. Fear is a powerful weapon and powerful weapons create fear. As long as there is power upheld by armed forces, there will be a fear of that power and control will always follow. Technology and AI can only take us so far. Until fear is removed as the instrument of control, we are stuck in a box and power dictates how the world will be. This does not mean that we don't have a say. Many great minds are working hard to create the future that they want to see. The people in control are always working to keep control and see all of the things that threaten that control. They are working to stay a few steps ahead of the cutting edge changes that are coming. They are preparing for them. They will need to adopt blockchain technology because they can't beat it. They see it coming and are already preparing us. I hope that some can stay a step ahead of those trying to stay a step ahead... it is a tall order. If we are to become truly free as a people, we need to see the power for what it is, and see the steps they are taking before they take them.

Sorry for painting such a bleak picture. The power struggle has been going on for a really long time. It crucified Christ, killed JFK Martin Luther King, Malcolm X, Gandhi, brought the rise of Hitler, Bush, Trump etc. Power is willing to go great lengths to keep it. They see blockchain tech, AI and know what it is capable of. They have been planning a way to implement it and keep control. Keep your eyes open.
