Ironically post-singularity AIs might be more like Master Computer from Tron. Just believing they are super efficient and can run things better. But to whose benefit?

I have the vision that AI will eventually replace all the CEOs, being even more efficient than them at whatever their job is. This means even more exploitation of workers, hoarding of wealth, and putting profits above all else. The true nightmare. I think that AI will eventually turn all corporations into pure evil, and turn all humans against AI and therefore corporations. That will result in a civil war - humans vs machines. Eventually, humans will be able to save themselves, but only by putting capitalism and the system of ever rising profits to the grave for good.
