in the happy end of the movie, baumann realizes dr. heller's vision in which robots improve the lives of everyone and are used to do "dangerous, unhealthy and intellectually suffocating" jobs. the workers replaced by the robots don't lose their jobs but are instead employed in other areas – such as for the maintenance of the robots. preserving workers' jobs also becomes a condition for the customers of the company's robots and thus humans are freed for a more worthy and humane life.
