A fundamental characteristic of capitalism is that capitalist businesses are run as dictatorships, with the capitalists as the dictators. When is the dictator going to replace themselves? Never. If anything, the capitalist will fully automate their job and continue to control all of the profits and continue to run the organization as a dictator. Most capitalists already do some form of this, they just hire other people to do work while they do little to nothing yet continue to "own" the organization, which is why the setup is so good for them, and why their job could be so easily replaced by AI. Unless the structures of businesses change and capitalists no longer have dictatorial authority over hiring/firing.
