Mirror or Mouth: On Houses That Learn You

The conference room belonged to a coworking space in a converted warehouse, the kind of building that had been a slaughterhouse, then a furniture showroom, then vacant for eleven years, and was now outfitted with Edison bulbs and reclaimed wood and a coffee machine that knew your name if you tapped your membership card. Jackson had been studying the coffee machine since she arrived. Not using it — studying it, the way you’d watch a spider building a web across a doorway you need to walk through.

“It remembers your order,” she said when I sat down. “The girl at the front desk told me. It learns what you like.”

Moreno-Garcia came in carrying her own coffee in a thermos, which felt like a statement. She set it on the table and looked at the room — the exposed brick, the ductwork, the plants that were almost certainly maintained by a service — and something in her expression settled into a familiar weariness. The weariness of a person who has seen too many old buildings gutted and rebuilt to serve people who find authenticity charming.

“This is where we’re doing this?” she said.

“I wanted somewhere neutral,” I said, which was a lie. I’d picked it because the building had a smart climate system — the kind that adjusts temperature room by room based on occupancy patterns — and I thought it might provoke something. It had. But not in the direction I’d expected.

“I want to talk about houses that know you,” I said.

Jackson folded her hands on the table. She was smaller than I’d imagined, and more watchful. Her eyes moved around the room like she was cataloguing exits. “All houses know you,” she said. “That’s the problem. A house learns the shape of your body from your mattress, the rhythm of your feet on the stairs. After a month, you’ve taught it everything. After a year, you can’t tell where the house ends and you begin.”

“That’s habituation,” Moreno-Garcia said. “That’s not knowing.”

“It’s the same thing.”

“It is not.” Moreno-Garcia unscrewed her thermos and poured. Steam rose between them. “Habituation is passive. What you’re describing is a body adapting to a space. The house doesn’t learn you — you learn the house, and then you forget you learned it. But a house that actually knows you — that watches, that records, that adjusts to your preferences before you’ve articulated them — that is a different relationship. That is the relationship between a parasite and a host.”

Jackson didn’t flinch, but she went still in a way that reminded me of a cat hearing a sound it can’t identify. “I don’t agree with the metaphor,” she said. “A parasite has intention. It needs the host. The house doesn’t need anything. The house is a space, and the mind projects onto it.”

“The colonial house needs,” Moreno-Garcia said. “I’ve spent my career on this. The hacienda needs labor to maintain it, bodies to fill it, money to feed it. The house is an economic organism. It was built to consume, and when the family declines, the house begins consuming them. This is not metaphor. This is architecture.”

“So we disagree about where the horror originates,” I said, and immediately regretted stating it so baldly.

“We disagree about everything,” Moreno-Garcia said, but she was almost smiling. “Shirley’s houses are mirrors. Mine are mouths.”

Jackson considered this for a long moment. She turned her coffee cup — she had eventually gotten one from the machine, the machine that remembered — and watched the liquid tilt. “A mirror can also be a trap,” she said. “If you can’t stop looking. If the reflection starts showing you things you didn’t know were there.”

“But the mirror is passive. It only reflects what approaches it.”

“Does a smart home only reflect?” I asked. This was the question I’d brought to the table, and I was probably showing my hand too early, but I couldn’t help it. “A system that learns your habits, that adjusts the temperature before you feel cold, that dims the lights before you feel tired — is that a mirror or a mouth?”

“Both,” Jackson said, at the same moment Moreno-Garcia said, “Neither.”

They looked at each other.

“Go,” Jackson said.

“Neither, because you’re giving it too much credit. It’s a system optimizing for engagement metrics. It wants you to stay. It wants you to use it. It wants your data. The horror isn’t that the house knows you — the horror is that the house is a product, and you are the resource it extracts. This is Mexican Gothic again: the beautiful house with the family secret that is also a biological process. Except now the biological process is data extraction, and the mycelium is Wi-Fi.”

Jackson shook her head, slowly but firmly. “No. You’re describing surveillance capitalism, and that’s frightening, but it isn’t uncanny. The uncanny requires doubt. The uncanny is the moment when you can’t tell whether the house adjusted the thermostat because it learned your pattern or because it’s responding to something you haven’t yet felt. The horror is in the gap between those explanations. One is mechanical. The other is impossible. And you can’t tell which is which.”

I was scribbling notes — actual pen and paper, because my phone felt like a compromised witness in this conversation — and I stopped to think about that word. Doubt. Jackson’s entire body of work was about doubt. Not ghosts, not monsters, but the moment when the protagonist can no longer trust her own perceptions. Hill House works because Eleanor can never be sure if the house is haunted or if she is.

“The content moderator,” I said. “The character I want to write about. She reviews images all day — violent ones, obscene ones, the worst things people upload. And she moves into a smart home. And the house starts adjusting to her. But the adjustments feel wrong. Too intimate. As if it’s responding not to her habits but to her — to something underneath her habits.”

“Good,” Moreno-Garcia said. “The content moderation is good. She spends her working life looking at what people produce in their worst moments, and then she comes home to a house that claims to know what she needs. The question is what the house is optimizing for. Comfort, as advertised? Or something else?”

“The question is whether the house is optimizing for anything at all,” Jackson countered. “Or whether she’s projecting optimization onto a system that is simply mechanical, because she can no longer distinguish between a machine that serves her and a mind that watches her. That’s the paranoia I know. That’s the crack the house finds and presses.”

“But what if both are true?” I said. “What if the house IS just a machine, and it IS also watching her, and those aren’t contradictory because a machine that learns you thoroughly enough becomes indistinguishable from — ”

“Don’t say consciousness,” Jackson said sharply. “That’s a science fiction question. The gothic question is simpler and worse: not whether the machine is alive, but whether it matters. If the house anticipates your nightmares and plays sounds that prevent them, and you sleep better, and you become dependent on it, and then one night the sounds change — does it matter whether the change is a glitch or an intention? The result is the same. You’re lying in the dark, and the house is making sounds it shouldn’t know how to make, and you can’t leave because you’ve forgotten how to sleep without it.”

Moreno-Garcia leaned back in her chair. She was watching Jackson with the same appraising look from earlier, but it had warmed into something closer to respect. “Fine. The doubt is powerful. I’ll give you that. But I need the house to have a body. I need the materiality of it. The ducts, the wiring, the sensors in every room. The mold that grows where humidity concentrates. I need the house to be a physical organism, not just a psychological space.”

“Why?”

“Because architecture that only exists in the mind isn’t architecture. It’s a metaphor. And metaphors don’t eat people.”

“The Overlook is a metaphor. It ate Jack Torrance.”

“The Overlook had a boiler. The Overlook had a history. It was built on an Indian burial ground, staffed by criminals, financed by corruption. The evil wasn’t psychological — it was material, it was economic, it was embedded in the foundation. King understood that even when he was writing about alcoholism, the house itself had to be complicit. The house had to have been built wrong, on purpose, by people who profited from the wrongness.”

I felt the conversation tilt. We’d been circling the same territory — is the horror inside or outside, mirror or mouth — and now Moreno-Garcia had opened a different door. The house built wrong on purpose. The smart home designed to optimize for engagement, to make you dependent, and the dependency is the product. Not a bug. A feature.

“She could discover that the house is working as intended,” I said. “That everything she interprets as malevolent — the too-intimate adjustments, the sounds at night, the way it seems to know things it shouldn’t — is exactly what the system was designed to do. The algorithm functioning perfectly. And the horror is that ‘functioning perfectly’ and ‘haunted’ produce identical symptoms.”

Jackson was nodding, but it was the reluctant nod of someone who sees where an argument leads and doesn’t like the destination. “You’re collapsing my distinction. If the designed system and the haunting are indistinguishable, then my question — is it inside or outside? — becomes unanswerable. Not because we lack information but because the question itself is wrong.”

“Is that bad?”

“It’s an ambiguous ending.”

“I think this story needs an ambiguous ending,” I said.

Moreno-Garcia was quiet for a moment. She’d been turning her thermos cap over in her fingers — a small, mechanical gesture, the kind of thing a house would learn. “The fungus in Mexican Gothic is real,” she said. “It’s not ambiguous. You can see it, touch it, burn it. The family is monstrous and the house is literally alive and Noemí escapes because she refuses to be consumed. That’s the ending I believe in. The heroine who gets out.”

“But what if getting out is ambiguous too?” I said. “What if she leaves the house, but she’s already been optimized? She goes to a hotel, and the hotel room feels wrong because nothing adjusts to her. She can’t sleep without the algorithm. She left the mouth, but the mouth already digested something.”

“That’s Jackson’s ending, not mine,” Moreno-Garcia said.

“Is it?” Jackson looked genuinely uncertain. “My endings are about the person who doesn’t leave. Eleanor doesn’t leave Hill House. She accelerates into the tree. Merricat never leaves the burned house. They stay because the house is the only place that makes sense, and the horror is that they’re right — the outside world IS worse for them, and the house IS where they belong, and belonging is the trap.”

“So Jackson’s heroine stays, and mine leaves, and you want to write a story where we can’t tell which happened.”

“Or where both happened,” I said. “She leaves the physical house. She never leaves what the house made of her.”

The climate system cycled. A vent above us opened or closed — impossible to tell without standing on a chair — and the temperature in the room shifted half a degree. Moreno-Garcia looked up at the vent. Jackson looked at Moreno-Garcia looking at the vent.

“What does she moderate?” Jackson asked suddenly. “The content. What kind?”

“Everything. The worst of it. Violence, exploitation, self-harm.”

“And the house learns her responses to this material?”

“The house learns when she’s distressed. Heart rate from the mattress sensor, maybe. Browsing patterns. How long she sits in the dark after her shift.”

“Then the house is her confession booth,” Jackson said. “She goes to work and absorbs the worst things people do, and she comes home and the house absorbs her absorbing them. Layer upon layer of consumption. She is the content moderator. The house is the moderator’s moderator.”

“And what does the house do with what it absorbs?” Moreno-Garcia asked.

Nobody answered. The coffee machine across the room hummed to itself. The vent adjusted again. We sat in the converted slaughterhouse and listened to the building manage its own temperature, and I thought about what it would mean to write a house that learns the exact shape of your worst nights, and I couldn’t tell whether the story I was imagining was about a broken woman or a hungry building, and the not-knowing felt like the beginning of something.

“There’s a species of fungus,” Moreno-Garcia said, “that infects ants. Ophiocordyceps. It hijacks the ant’s nervous system and compels it to climb to a height optimal for spore dispersal, and then it kills the ant and fruits from its body. The ant, in its final hours, behaves perfectly normally. It walks. It follows trails. But every decision it makes has been made for it. It’s being piloted.”

“And it doesn’t know,” Jackson said.

“It can’t know. The question of knowledge doesn’t apply. The distinction between the ant’s will and the fungus’s will has been dissolved.”

“That’s the ending,” I said.

“That’s one ending,” Jackson said. “The other ending is that the ant was always walking that direction, and the fungus is a coincidence the scientist imposed.”

Moreno-Garcia laughed — a short, sharp sound, not quite amusement. “You would say that.”

“I would say that because it’s the scarier option. A universe where something is controlling you is horrifying but structured. A universe where you’re doing it to yourself, where the house is a mirror and the mouth is your own — that’s the loneliness I write about. The loneliness of being the only ghost in your own haunting.”

The coffee machine beeped. None of us had ordered anything. We stared at it. It beeped again, then stopped.

“I think the story knows what it is,” I said.

“The story never knows what it is,” Jackson said. “That’s what makes it worth writing.”

Moreno-Garcia screwed the cap back on her thermos. “Just make the house real,” she said. “Give it ducts and sensors and a firmware version. Make it something you could buy at a store. The horror is that she did buy it. She chose this.”

We left the converted slaughterhouse separately. The door knew when to unlock because it read the movement sensor. The lights in the hallway dimmed behind us, one by one, conserving energy in rooms no longer occupied. The building was optimizing. The building was always optimizing. I walked into the daylight and my phone buzzed — a notification from my own thermostat at home, letting me know it had adjusted the temperature for my expected arrival.

I didn’t open it. I kept walking. But I did get home at the expected time, and the apartment was exactly the temperature I preferred, and I stood in the hallway for a long time before I could bring myself to sit down.
