The irony of the work exists in how a computer, rather than a human, discusses a process of dehumanization. The speaker's comments, taken to be self referring, describe a descent into, as psydereal noted, a protestant work ethic hell. Pragmatism over idealism, as well as fondness over love, are preferences which are certainly more productive; idealism tends to provoke revolutions and love tends to promote the cutting off of one's ear. What these choices lack is the element of purpose. I may be fond, but am I really feeling anything? Thus, the final scary metaphor to that pig.
The whole work is very frightening. Between the secondary voice that jumps in with disagreements, take a good look at line 14, and the metaphor of the cat, I felt the need to rapidly run my hand into the side of my face in order to make sure I was still there.
