This is a wrong assumption, at least from my point of view. Your purpose in life is to work like a slave until you die most of the time poor? Machines (in general) are made for working, not the people. The best and biggest tool that humans have is their brains. The brain doesn't have hands or legs and its purpose is to "work" continuously to make our lives better without the necessity to work like a machine. That's why we invent them. This alone proves that instead of losing our abilities, we find new ways to evolve and move on as a species.
AI missing critical and/or emotional thinking which is good to have for running a business. Also, it can't choose which is the best field for you to get involved in since it's missing info that you know and basically, nobody else. So instead of making all this effort by putting all your's brains data into an AI, start learning and improving your knowledge and skills and you will certainly become better at running the business that you will decide based on what you want.
