AI is already owned by the elites who already own the world. The AI revolution has nothing to do with change of ownership.
A small group of people own most of human wealth. Remember the 1%? Well, it's more like the .0000001% who control the world's corporations through interlocking directorates. This is common knowledge to anyone with some intelligence, is not wearing a bag over their head and does a little honest research.
AI developers work for the companies owned by the elite, hence the elite control AI.
