Eventually, Trurl gets tired of all the work and builds a computer that will contain a programmatic clone of his mind that would do the research for him. Instead of building new worlds, the computer sets about expanding itself. When Trurl eventually forces it to stop building itself and start working, the clone-Trurl tells him that he has already created many sub-Trurl programs to do the work and tells him stories about their research (which Trurl later finds out is bogus). Trurl destroys the computer and temporarily stops looking for universal happiness.
