It is assumed that when AI and blockchain come together, they provide more security, but we do not know what side effects it might have, and if something is done, it has to be 100% perfect, because if there is a failure they can dominate the world by themselves.
Artificial intelligence in time will replace human work that requires precision so that it can prevent failure in his work. For example, bitcoin transactions that absorb emotions and energy are very tiring, can be replaced by robots that work without expression in executing trade. Robots take policies based on orders that have been programmed in such a way.
