By the time you finish this story, tens of millions more words will have been exchanged between humans and a machine.
The world’s biggest conversation (that nobody can see)
In November 2022, a small text box opened on the internet and asked the world a simple question: “How can I help?”
By July 2025, that box had turned into the largest ongoing conversation in human history: 700 million weekly active users sending roughly 18 billion messages every week — about 2.5 billion messages per day, or ~29,000 messages per second. That’s one in ten adults on Earth talking — often daily — to a chatbot.
You might think this would be a story about programmers automating work or students cheating on essays. It isn’t. After analyzing a massive, privacy-preserving sample of real ChatGPT conversations, researchers found something quieter and far more profound:
Most of what people do with ChatGPT isn’t work.
And the single most common “work” thing they do isn’t coding. It’s writing.
