San Francisco still operates three lines of 19th century cable cars, sharing the streets with 20th century automobiles and 21st century self-driving Waymos and Zoox autonomous vehicles.
I’m living in San Francisco for a few months for my job at an AI insurance startup. The apartment I’m subleasing is on the path of one of the cable car lines, and so is my office. I’ve been taking the cable cars regularly, because it’s the most direct way from my home to my work.
It’s funny to regularly use the old-fashioned cable cars because they’re mostly used by tourists. Tourists only use them once. On my way home from work, tired and wearing my backpack, I’ll share the wooden cable car seats with old people riding the cable cars for the first time, holding up their phones to take photos of downtown from the top of the hills as the cable cars slowly climb.
The cable cars are not an optimized form of transportation. They are slow, and they stop often. But this doesn’t matter to tourists, who aren’t riding them for efficiency.
The cable car drivers are very sweet to the tourists. The cars are small, every seat in audible range of the driver, so the passengers are an audience for them. They act like operators of theme park rides, narrating the journey. They point out good spots for photos and say fun facts about the city of San Francisco.
Once, I had to wait for five minutes for my cable car to climb a hill, because a human-driven car was blocking the way. A boy was letting a girl out of his car and they were saying goodbye. The cable car driver loudly rang the bell, but the human driver ignored the sound. Eventually, the girl exited the car, and the car quickly drove away.
“Ugh, get a room,” the cable car driver loudly proclaimed to his audience, “I’m taking donations to get them a room.”
Cable cars are different from Waymos. Waymos can navigate around obstacles, and they don’t need to stop until they get to the destination. There’s also not a human inside the Waymo to make small jokes. Sometimes that’s good, when you don’t want to talk to anyone else. It feels good to get in a Waymo with your friends and talk about whatever you want to on the way to the party, without worrying about the driver overhearing. But other times you don’t want to be alone.
I went to the cable car museum on a Tuesday, while on my lunch break. I went alone. The museum is free so I didn’t have to talk to anyone to get in. I didn’t tell my boss I was going, because he doesn’t need or want to know every detail of my life.
The museum holds four rows of giant gears, each of which supplies the motion of one of the cable car lines in operation today. When first invented in San Francisco in 1873, the cable cars required no electricity, able to be powered totally by steam. At the time of their invention, the cable cars opened up the tops of some large hills in the city for housing development, since some hills were too steep for horses to climb. The new centrally located reachable land reshaped the city’s effective geographic layout.
In the 1900s the cable car lost relevance. The city took down more cable car lines as the newer technology of the automobile took over. In the 1980s, now entirely owned by the government as a historical artifact to be preserved, the underlying infrastructure of the few lines remaining was rebuilt from scratch. A new skeleton to carry the old-fashioned cars.
Some of this I learned reading signs at the museum, and some of this I learned talking to Claude on my phone. There were four rows of gears in the museum, but only three cable car lines I knew of, so I talked to Claude to clarify. I learned from Claude that two lines share the same gear for their second half, which wasn’t clear on the signs that I read.
I didn’t talk to museum workers because there weren’t any. There was one guy working the gift shop. There was a guy in his 30s giving a tour to three women in their 50s, but I think that was unauthorized.
I thought about technology, efficiency, change, and being alone at the cable car museum.
--The entirely rebuilt cable car track from the 1980s slightly discolors the fantasy that this is the same cable car line as the olden days. Fantasies aren’t supposed to be efficient, but we rebuilt the old technology in a more practical way, in order to more efficiently imagine the past. But I guess the cable car is not solely a fantasy of the past. Some aspects of the cable car are nice even in the present. The cable car is open air, so riders can feel the California breeze, which is eternally good.
--Self-driving cars, now in competition in cities but soon to be accessible everywhere, are going to change the social fabric, like the cable cars did. Small things, like how I talk to my friends alone in the Waymo differently than I do when there’s a driver. But just like the cable cars opened up the tops of San Francisco’s hills, self-driving cars might also change our geography. Self-driving cars cause less mental load from driving, which means people might take cars further distances, opening up longer commutes and thus more remote areas.
--The AI on my phone is changing the social fabric too. What’s the best way to learn about the world around me? Should I listen to the human cable car drivers? Should I ask questions to the tourists from around the world, open to new experiences on their vacation, who’d likely be excited to talk to someone living in San Francisco working at a tech startup? Should I talk to Claude, who likely will give more specific, relevant, and accurate answers to my questions than the humans around me would? What’s the best amount to be alone?
It’s scary, but it’s possible that in the future engaging with humans around you in public to exchange information or small jokes will be like riding the cable car. A quaint, outmoded thing that one can technically do, but more commonly done during leisure time, when efficiency doesn’t matter. It might feel good, like the fresh air feels good, but when you need to actually learn something you’ll talk to artificial intelligence.
This might seem sad. But in some ways the arc of human progress shows that our preference is to be alone. The automobile made us more alone, driving by ourselves instead of sitting together on public transit, and it won as a technology. The television made us more alone, seeing the world from our house instead of going out to the bar, and it won as a technology. We imagine pasts and futures of ideal happy connection, but we keep inventing new, better ways to be alone.
Right now, I’m in San Francisco, but I can message my friends in other cities. That’s technology bringing me closer to humans. On my phone I can also message people who live in San Francisco who want to spend time with me in the city. I moved to San Francisco and instantly knew people because of the internet, which is special. These aren’t random people, like the people on the cable car. These are people I chose because I like them. Technology helps me find people I like and communicate with them across a large distance. This makes me feel good about technology and the future.
But other times my phone makes me feel sick. Sometimes because I’ve been on it for too long, receiving too much information, and other times for reasons I don’t understand yet. I need to set it down and feel the California breeze. Often on the cable car ride home, after a day on my phone and computer, I’m just sitting there looking off into space.
