You Can't Go 48 Hours Without AI: Here's What Happens When You Try

Presented by

Based on the April 9, 2026 Lead with AI PRO live session with A.J. Jacobs, New York Times bestselling author and editor at large at Esquire. Full recording here.

When A.J. Jacobs set out to spend 48 hours without interacting with any artificial intelligence, he thought it might be manageable. "They wanted me to do it for a week or a month, and I'm like, I can barely do 48 hours," he told the Lead with AI community.

The experiment, which became a viral New York Times feature, started as a sequel to his earlier piece about trying to go a day without plastic. "My editor and I noticed we think that AI is more prevalent than people assume," Jacobs explained. "So, what if we tried to go 48 hours without interacting with AI or machine learning? Where is it hiding in plain sight?"

He thought it might be easier than the plastic article. "But it was not. Because AI is everywhere."

AI is not just ChatGPT

The first thing Jacobs had to reckon with was the definition of AI itself. "Many people think AI is just gen AI, like ChatGPT," he said. "But actually, the definition of AI usually includes an umbrella that is also machine learning, which has been around for a couple of decades and is everywhere in our lives."

That broader definition turned a quirky challenge into something closer to time travel. "I couldn't wear my clothes, because they're designed using AI and sent on the supply chain using AI. I couldn't pay for my lunch, because credit cards use AI for fraud detection, and cash uses AI in being printed. I couldn't turn on the water, because the New York Reservoir system uses AI in deciding where the water should be allotted."

From Apple Face ID all the way to Zoom, and everything in between (garbage truck routing, traffic lights, the Netflix algorithm, news curation), the list of things Jacobs couldn't touch during his 48 hours was enormous.

Companies are hiding how much AI they use

One of the more revealing moments from Jacobs's reporting was what happened when he dug into the water system. An employee had explained how machine learning predicts water demand across neighborhoods. But when Jacobs contacted the official publicist, the reaction was very different.

"She got very nervous, because she was afraid that this would cause panic, and people would say, I don't want my water to be controlled by robots," Jacobs recalled.

That nervousness, he found, is widespread. "People are very nervous about revealing how much AI is being used." Organizations across industries are quietly relying on AI while actively avoiding the label.

For leaders working to build AI fluency across their organizations, this gap between what's actually happening behind the scenes and what people believe is a critical starting point.

The spectrum: glorified spell check to bigger than fire

Jacobs talked to dozens of experts while reporting the article, and the range of opinions was wild. "You had people saying AI is glorified spell check. And then, on the other side, you had people saying AI is the biggest invention in human history, bigger than fire, because fire did not replace humans."

By the end of the experiment, Jacobs had moved. "I was more towards fire. I don't think it's a fad, I don't think it's a stochastic parrot, as some people call it. This is a genuine revolution."

He was direct about the article's intent: "Part of the article was to push people in that direction, to show this is not a fad. This is a genuine revolution."

Two competing stories about AI and the future of work

Jacobs shared a tension he keeps encountering in conversations with people in the tech world. "I was having dinner with a woman at Google who does human-AI interaction, and she was stressing the story of democratization, that AI is going to empower entrepreneurs to compete with big companies."

But that's only one version. "Another story that I hear just as often is that it is going to be a winner-takes-all world. Because of the positive feedback loop of AI, as soon as one company gets a slight advantage, they can replicate and create a hundred workers to do the same job more quickly, and then those hundred can create another thousand. So it will be a world where it's the 0.01% and the rest of the 99.9%."

Jacobs didn't pretend to have the answer. "I am not enough of an expert, and I don't think anyone is, to know which is the correct one." But he's rooting for the first version: "It does have the potential to create this wonderful scenario where you don't have to have half a million dollars to hire people, that you will be able to use AI as your starting staff."

The entry-level job problem nobody has solved

One of the most striking insights from the session came from a conversation Jacobs had with a startup founder who uses AI for most of his coding.

"AI is poised to replace a lot of the entry-level jobs. But what happens when you need that next step on the ladder? Can that person do the job of being in charge of the AIs without having gone through the boot camp of that entry-level job?"

The founder's solution surprised Jacobs: "He says, let's take a week off where you have to do the grunt work that you would normally offload to AI. Try coding without AI, just so you remember and get a feel for it."

Jacobs framed the open question directly: "How much grunt work should we voluntarily do just to be able to manage the AIs?" For organizations building AI champion programs, this is one of the harder design questions to get right.

Using AI to research an article about avoiding AI

Jacobs was upfront about the irony of the whole thing. "This article was about how I stopped using AI for 48 hours, and yet, in preparation for the article, I used a ton of AI, which I admitted in the article. I tried to be upfront."

The New York Times, he explained, has clear rules: "You're not allowed to let AI write anything for the New York Times, but you are allowed to use it for research. And it was amazing. I used ChatGPT and a couple of deep learning prompts, and the stuff that it found was far beyond Google, because it also searches PDFs."

But the research process taught him something important about how AI works. "AI is very obsequious. It's like a brown noser. It sensed my thesis, and the thesis was AI is everywhere, even where you don't expect it. And it started to really cater to that thesis. It would say, you know, AI is here, AI is there, and I would say, can I see sources? And it would say, well, I might have exaggerated a little."

That experience changed how Jacobs prompts. "I now say, show me sources. I try to say, show me both sides of this issue. Don't just cater to what you think I want." He's particularly fond of a technique he called steel-manning, the opposite of straw-manning: "Stating the opponent's point of view in the strongest possible way. I said, can you steel-man the other side? What are the pros and cons of this, as opposed to what are the benefits? Everything has cons and pros."

What AI can't do: perspective-taking and lived experience

When asked what human qualities will remain essential, Jacobs went straight to the through-line of his career. "One of the theses of all of my stuff is walking a mile in someone else's shoes, experiencing the world from another point of view to learn what their experience is like."

In business terms, he connected it to dogfooding. "You're supposed to experience what the customer experiences, even if you're, you know, you own a dog food company, you should taste the dog food." That kind of perspective-taking, he argued, "is something that AI can't do. Whether that's just an intellectual exercise, or actually going out, and, you know, you own a car wash company, going and putting on a wig and a mustache and going through the car wash to see what it's like."

Jacobs sees his own career as what he called "AI-resistant, not AI-proof." His articles are deeply experiential, first-person. "I go and I try to live according to the Bible. Until the AIs are android-like robots that look and act like humans, that's going to be hard for them to replicate."

But he was honest about the limits: "If it's just a non-fiction article or book, like the history of Russia, I'm not sure that humans will be able to do a better job than AI." His friend Kevin Roose at the New York Times recently ran a quiz where readers compared AI writing to writing by established authors, "and people were fooled. I think people overall preferred the AI writing."

AI is changing human behavior in unexpected ways

Jacobs brought up research from a Yale professor showing that our interactions with AI are changing how humans treat each other. "Kids, when they talk to Alexa or Siri, instead of saying, oh, hi Alexa, could you please tell me what the weather is today, they would just say, Alexa, weather. And that had a leak-over effect into humans, that humans are becoming less polite to each other, because of the influence of AI."

Jacobs admitted his own kids make fun of him for being polite to Alexa, but he has his reasons. "One, just this worry that my interaction with bots would leak over into human interaction. But then the other, if there is, God forbid, a robot apocalypse, I want them to be like, oh yeah, this guy was nice to me. This guy was one of the good ones, so we're gonna spare him."

AI-generated book knockoffs and phantom book clubs

Jacobs shared two personal examples of AI disruption in his own industry. When his book The Puzzler came out, he searched for it on Amazon. "There were about 10 other books called Summary of The Puzzler by A.J. Jacobs, or Puzzler Digest by AJG, and they were all AI-created books where they would stitch together reviews and little sections from my book." At the time they were pretty bad, "but now I would be scared, if I write another book, what AI is able to do with a summary."

The other example is more insidious: "I and all of my other author friends get several emails a week saying, hey, this is John Smith from the Seattle Book Club. We have 1,400 members, and we would love to feature your book." Then comes the pitch for money, contributions to the "refreshment budget" or to print posters. "It is all a scam to try to get people to give money to these non-existent book clubs."

The ethical question leaders need to answer now

Jacobs connected his AI reporting to his recent work on the history of advertising. "The dark side of advertising is you can motivate people to buy things by appealing to fear and insecurities," he said, pointing to the classic mouthwash ad that told women "always a bridesmaid, never a bride" unless they fixed their bad breath.

"I think AI will be very good at finding what makes us most insecure and fearful," Jacobs warned. His question to leaders was direct: "If you are head of a marketing or advertising company, do you want to use this tool, this very effective tool of scaring people to buy your product? Or will you be okay with making 5% less, but using something positive, how it'll make your life better?"

"Thinking about the mission, thinking about the bigger picture, those are the things that humans will absolutely be necessary for."

Experiment with your life

Jacobs closed with a message that ties together his decades of immersive experiments, from living by the Bible to reading the Encyclopedia Britannica to thanking a thousand people for his morning coffee.

"I am very pro-experiment with your life. You don't have to grow a beard and wear a robe and try to live like the Bible, but small experiments, whether it's trying a new toothpaste every time you buy a toothpaste tube, or whatever, just to keep your life fresh, your brain making new connections."

Key takeaways

  • AI is embedded far deeper than most people realize. Jacobs's experiment showed that clothing, water, payments, transportation, lighting, and entertainment all depend on AI or machine learning, and companies are actively hiding this.
  • The entry-level job gap is real. If AI handles the grunt work, the next generation of managers may lack the hands-on experience needed to direct AI. Build deliberate practice into your team's development.
  • AI is a sycophant by default. When using AI for research or decisions, explicitly ask it to steel-man the opposing view and demand sources.
  • Perspective-taking is the most AI-resistant skill. The ability to physically experience the world from someone else's point of view remains irreplaceable.
  • Decide your ethical lines before the tools get better. AI will make manipulation cheaper and more precise. The question isn't whether it can exploit insecurity, it's whether you'll let it.
