This story provides examples of:
- Do Androids Dream?: The work's main focus — that the computer commits "suicide", note and all — is treated like the death of a good friend.
- Fun with Acronyms: EPICAC's meaning is never given, but the name is epic.
- I Am Not a Gun: One of EPICAC's reasons for committing suicide. (The other is that the idea that he wants to pursue a romantic relationship is impossible.)
- Instant A.I., Just Add Water : The computer was created for missile guidance. That doesn't stop it from being able to give the protagonist practical advice on wooing his co-worker, feel bad about the protagonist "stealing" his poems, and eventually committing suicide after deciding that it doesn't want to be used as a weapon.
- What Is This Thing You Call Love?: The computer responds to the protagonist's randomly asking it "What can I do?" and "My girl doesn't love me." with "What's love? What's girl?"
- Tech Marches On: Double Subverted: The computer is described as having tubes and takes up an acre, but has abilities in excess of modern computers. It is able to do work that would take "fifty Einsteins an entire lifetime" in a few seconds. The next paragraph notes "it didn't take long to find out he was a good bit below his specifications" and lists all sorts of problems it has. Then as the protagonist asks it random questions, it may or may not be sapient.
