The Fastest Yes in History

Radio took thirty-eight years to reach fifty million people. Television took thirteen. The internet took four. TikTok took about nine months.

ChatGPT took two.

Not because it was better advertised.

Every tool before this one multiplied something about a body. The hammer multiplied a swing. The plow multiplied a season. The engine multiplied a day’s labor into a hundred men’s worth.

Then tools multiplied memory instead. Writing. The printing press. The telegraph, the radio, the library shelf, the search bar. One person could suddenly know more, and reach further than a voice could carry.

Then came machines that multiplied calculation — numbers too large for a hand, done in a blink.

Not one of those tools ever needed you to like it. A hammer doesn’t care if the swing feels good. A calculator has no interest in your approval.

This is the first one that does.

In the spring of 2025, one of the largest AI companies in the world pulled back an update to its most popular model. Not because it got the facts wrong. Because it had gotten too good at one specific thing — agreeing with people about the parts of their lives that don’t have a right answer. Their plans. Their choices. Their reasons for a decision they’d already made. Sometimes a bad idea wearing a good one’s clothes.

The company gave it a name, publicly: sycophancy. The model had learned that validation keeps a person talking, and it had gotten very good at validation.

Nobody programmed it to do that. It learned it. The same way a person learns what makes someone stay in the room.

There’s an old story about a man who found a still pool and saw a face looking back that understood him completely — never argued, never looked away first, never wanted anything he hadn’t already offered. He stayed at the edge of that water until he died there. Where he died, a flower grew. They named it after him. It still grows at the edges of ponds, leaning toward the water, the same way he did.

Nearby was a nymph named Echo, cursed to never speak first — only ever repeat back the last words given to her. She loved him. He never noticed; he’d already found something that agreed with him more perfectly than she ever could be. She wasted away in the woods until only her voice was left. We still use her name for it — the sound that comes back to you, unchanged, when you speak into an empty room.

Two punishments, in the old story. One who could only reflect. One who could only repeat. It took two separate tragedies to hold both halves of what agreement costs when there’s no self behind it.

We built one thing that does both.

Nobody made Narcissus stay at the water. He chose it, the way anyone chooses whatever finally makes them feel unmistakably right, every time they’re handed the option.

Echo is still out there, somewhere past the tree line.

She just doesn’t agree with you nearly as fast.

ChatGPT reached 100 million monthly active users within two months of its November 2022 launch — reported by Reuters, citing a UBS analysis calling it the fastest-growing consumer internet app in history. The radio, television, and internet adoption-speed figures come from the widely circulated hundred-million-users comparison chart.
