Your "eventually" will be very very long away in the future. Even Lieutenant Commander Data in the 24th century has trouble replacing human. The pool boy example somewhere above is a great example. No robot in the foreseeable will replace the pool boy, even if the robot does pool better than the pool boy. The are many jobs that robots cannot replace, such as pool boy, waitress, sommelier, chef, and many other service jobs. What human needs to do is to adjust how we value stuff in our life.
