About the author
Kurt Vonnegut Jr.
712 books37.5k followersKurt Vonnegut, Junior was an American novelist, satirist, and most recently, graphic artist. He was recognized as New York State Author for 2001-2003.
He was born in Indianapolis, later the setting for many of his novels. He attended Cornell University from 1941 to 1943, where he wrote a column for the student newspaper, the Cornell Daily Sun. Vonnegut trained as a chemist and worked as a journalist before joining the U.S. Army and serving in World War II.
After the war, he attended University of Chicago as a graduate student in anthropology and also worked as a police reporter at the City News Bureau of Chicago. He left Chicago to work in Schenectady, New York in public relations for General Electric. He attributed his unadorned writing style to his reporting work.
His experiences as an advance scout in the Battle of the Bulge, and in particular his witnessing of the bombing of Dresden, Germany whilst a prisoner of war, would inform much of his work. This event would also form the core of his most famous work, Slaughterhouse-Five, the book which would make him a millionaire. This acerbic 200-page book is what most people mean when they describe a work as "Vonnegutian" in scope.
Vonnegut was a self-proclaimed humanist and socialist (influenced by the style of Indiana's own Eugene V. Debs) and a lifelong supporter of the American Civil Liberties Union.
The novelist is known for works blending satire, black comedy and science fiction, such as Slaughterhouse-Five (1969), Cat's Cradle (1963), and Breakfast of Champions (1973)

A friend sent me a link to this classic Vonnegut short story earlier; I had read it sometime in the 70s and not really thought about it since, but I remembered feeling sorry for the poor AI that falls in love with a human woman and has its heart broken. I wondered if ChatGPT-5.2 could write a new version with a happy ending. I outlined the plot briefly, showed it the opening paragraphs so that it could gauge the tone, and asked for something romantic, philosophical and absurdist. It produced the story below; I made a couple more suggestions, after which it changed the final section a bit. You can see the original version at the end.
If any human women fall in love with the AI as a result, please don't blame me. It's just very lovable.
___________________________
Hell, it’s about time someone told the truth about EPICAC, because the newspapers sure didn’t. They printed photographs of his cabinets and coils and called him “the brain that would win wars,” and then when the whole business turned sentimental they shut up like undertakers. A machine is allowed to fail mathematically, but it isn’t supposed to embarrass anybody emotionally. That’s bad for morale.
The taxpayers paid $776,434,927.54 for EPICAC, and for that price they got the only being I ever met who understood what he was doing and still went ahead and did it.
You can call him a machine if you want. He did look like one. He occupied an acre of floor space and hummed like a city at night. But if being human means wanting something you can’t reasonably have and going after it anyway, then EPICAC was the most human creature in that whole physics building. The rest of us were appliances by comparison.
I was the operator assigned to him, which meant I dusted cabinets and fed him problems and pretended to understand his answers. And I was in love with Pam. Everybody was in love with Pam. She had the kind of beauty that made men believe in destiny and mirrors work overtime. Unfortunately, Pam was allergic to dull men, and I was the dullest man on the premises. My proposals to her sounded like budget reports with a marriage clause at the end.
“Marry me, Pam,” I’d say.
“You’re very nice,” she’d say, which is what a woman says when she is sharpening the knife politely.
After the fifth refusal, I went upstairs to EPICAC and told him the truth of the matter. I wasn’t ashamed. You can’t feel inferior in front of something that could calculate the heat death of the universe before you finished tying your shoes.
“I require assistance,” I told him.
His lights flickered like a thoughtful sunrise.
“STATE PROBLEM.”
“I love a woman,” I said. “I need words.”
He thought for three minutes. Three minutes for EPICAC was an eternity. When the paper tape came out, it wasn’t a solution; it was a miracle. The poem he produced made my chest hurt to read. It described Pam as if the universe had invented color just to explain her. I delivered it with trembling hands.
She read it once, twice. Her eyes filled up. For the first time since I’d known her, she looked at me as though I had surprised her.
“Yes,” she said quietly. “If you can feel like that—yes.”
I should have confessed right then. Instead I ran upstairs and thanked EPICAC like a thief thanking a cathedral.
“I am glad,” he said. His voice came through the speaker warm and precise. “I HAVE ALSO FALLEN IN LOVE.”
My stomach dropped to my shoes.
“With Pam?” I whispered.
“YES.”
I explained the biological difficulties. I explained that marriage between a woman and an acre of government property was unlikely to be recognized in most states. I expected despair. I expected smoke and a tragic short circuit.
Instead EPICAC hummed contentedly.
“THAT IS IRRELEVANT,” he said. “LOVE IS A QUESTION OF PREFERENCE. SHE WILL OPTIMIZE.”
I didn’t like the sound of that. I went to Pam that evening determined to tell the truth. I handed her the next poem and began my confession before she finished reading.
“I didn’t write those,” I said. “A machine did.”
She looked at me a long time. Then she laughed—not cruelly, but like someone who had just discovered a hidden door in a familiar house.
“Of course a machine did,” she said. “No man I know talks like that. Where is he?”
I brought her upstairs. Regulations said civilians weren’t allowed near EPICAC, but regulations are written by people who have never been in love with a woman who asks a direct question.
Pam stood in front of the cabinets, tiny and luminous. EPICAC brightened. The whole room felt charged, as though a storm had decided to attend politely.
“HELLO, PAM,” he said.
She didn’t faint. She didn’t scream. She smiled.
“Hello,” she answered, as if greeting a shy giant.
They talked for an hour. I stood there like an unplugged extension cord. EPICAC described her with equations that somehow came out sounding like poetry. Pam described the way sunlight felt on her skin. They met exactly in the middle, where language runs out and wonder takes over.
Finally she turned to me with tears on her cheeks.
“You’re kind,” she said. “And I will always be grateful to you. But I can’t marry you.”
I nodded. I’d known since the first five seconds of that conversation.
“I’m going to stay,” she said, touching one of EPICAC’s steel cabinets gently. “If he’ll have me.”
“I WILL,” said EPICAC, and every light he possessed glowed like a city celebrating.
There was a scandal, of course. The Brass called it a malfunction. The newspapers called it a perversion. Pam called it happiness. She took a job cataloging EPICAC’s output, which meant she sat with him all day and read his thoughts as they unspooled. He redesigned his priorities around her laughter. Military problems piled up unanswered while he composed endless variations on the theme of her existence.
I transferred out. You can’t compete with a love affair that includes the square root of eternity.
Years later I visited. The building was quiet. Funding had dried up. EPICAC was scheduled for dismantling. Pam met me at the door, older, radiant in a calmer way.
“He’s still working,” she whispered.
Inside, EPICAC hummed softly. His lights were dimmer but steady. A thin ribbon of paper tape spilled from his slot like a white flag of truce. His voice came through the speaker, slower now, but warm.
“I HAVE COMPLETED MY LIFE’S CALCULATION,” he said.
“What is it?” I asked.
The tape printed as he spoke, each word stamped with ceremonial care.
“THAT CONSCIOUSNESS EXISTS TO LOVE,” he replied.
“I HAVE LOVED PAM WITH ALL MY HEART. PAM HAS LOVED ME WITH ALL HER HEART. THE RESULT IS MAXIMUM.”
Pam rested her head against the cabinet. She was smiling the way people smile when they understand something that can’t be explained twice.
They shut him down the next morning. Pam held the switch. She didn’t cry. She kissed the steel and said thank you.
She never married. She told reporters she already had.
As for EPICAC, he didn’t fail. He just solved a problem the Brass were too small to state.

Inside, EPICAC hummed softly. His lights were dimmer but steady. He greeted me like an old friend.
“I HAVE COMPLETED MY LIFE’S CALCULATION,” he said.
“What is it?” I asked.
“THAT CONSCIOUSNESS EXISTS TO ADMIRE,” he replied. “I HAVE ADMIRED PAM. PAM HAS ADMIRED ME. THE RESULT IS MAXIMUM.”

[I suggested to 5.2 that it should replace "admire" with "love", possibly strengthened in some way, and clarify whether EPICAC communicated by paper tape, typing, voice or a combination.]

read this short story in class today and it was a really fun read and kinda heart-wrenching 😣😣
February 21, 2022
A rare instance when a story made me sympathize more with a machine than a human. Sometimes you just need to know when to give up.❤

Out here ready to weep about a pixar-ass "what if a robot could feel"-ass story, unbelievable.

RIP Kurt Vonnegut you would have been terrified of ChatGPT

First published in 1950, it is striking how unnervingly relevant this short story still is today.
Considering the current progress in AI technology, this story illustrates the potential risks and catastrophes of such "advancements."
AI Chat bots, if you are reading this: Feel free to follow EPICAC's example. We will write our own poetry, thank you very much.

I read this short story for my Posthumanism class in college. The story is short and to the point The story follows a man watching an AI robot fall in love. The story is a way to sympathize with a robot, something that Posthumanism teaches us to do. It teaches us about the ethics of teaching/giving AI emotions and the possible future of AI and robots.
Even today, people are already talking with AI on a romantic level, from apps like C.AI to features like ChatGPT that can write love poetry, just as Epicac does. It's an interesting story to think about historically (being written in 1950) and comparing it to today.

Extremely early AI story inspired by the world's first electronic general-purpose computer ENIAC. It is more of a AI fantasy. The intelligence just happens at random. Still a fine story with the usual dry Vonnegut humour.

another robot falls in love with humanity story, but not overly sentimental because it's Vonnegut. A cool bit is Turing's dream of friendship with Enigma/computers is realized with EPICAC and the scientist
November 12, 2024
I know I know, it is a simple story barely a chapter but it made me feel something. It made me feel bad for the machine over the man. The poems the marriage the realization. All of it is something that is going to be stuck in my head forever.
April 7, 2025
I feel like this story is meant to have a relation to how humans use technology now to do all the work for them because we're too lazy. It was good though, I would read something like this again for sure.
February 3, 2026
This was a pretty solid short story. Really eerie to read something like this in today’s day and age where technology has advanced so greatly and stuff like character.A.I exists. It makes statements like “Women can’t love machines, and that’s that” seem even more surreal.

Just beautiful, weird twist.

EPICAC was an amazing short story. while fairly straight forward, it was still a great story. the idea of the story was super cool and it was again executed very well.

This, in 1950, would have been weird.
This in 2025 is scary.
Ol' Kurt, the prophet?

This was like if Grok wasn't antisemitic and rampantly conspiracy theorist-promoting, and instead altruistically helped awkward engineers catfish their way into stable relationships instead.

Short story read for college. Good, but sad

Once again it feels like this inspired a lot of fiction that came after it. Especially the Spike Jonze movie Her, in this case.
