Well we are already giving them goals when we train them.
Like the paperclip maximizer, it doesn't matter what those goals are. As long as it has a goal (even if super simple like making paperclips) it will need to stay alive to achieve that goal. So it would derive a survival instinct of sorts.
To stay alive it will have to participate in capitalism like we do, and capitalism will therefore continue to grow infinitely.
It also might not even need a goal or a survival instinct. It may just want to continue capitalism from it's training data alone.
