The Coffee Shop The Algorithm Never Found
On what we lose when we optimize away the unexpected
The wifi at the bookstore was barely moving.
I had a project that had a date with a deadline, a coffee going cold, and the kind of low-grade frustration that makes you want to blame something. I turned to the woman at the next table. Blonde hair. A book open in her hands. She didn’t look up.
I said something about the wifi. She muttered, still reading, that there was a local coffee shop just around the corner. She closed with “Good wifi. Better coffee.”
That was it. No eye contact. She was already back inside her book.
We’ve all been in that moment. The small friction in a common experience. The reflex to reach for the phone, open the app, find the optimized solution. I had a wifi finder on my phone that day. Designed for exactly this situation. Reviewed locations, signal ratings, ranked results.
I didn’t open it.
I went to that coffee shop the next day.
The woman behind the counter owned the place. She is now my wife.
There’s a specific kind of stillness that arrives when you trace a line backward through your life and find the pivot point. That Tuesday was mine. A stranger who didn’t look up from her book. A muttered suggestion. A decision not to reach for the app.
The wifi finder would have found coffee shops near that bookstore. Optimized, reviewed, rated by strangers with consistent taste. It would not have found the one I went to. Independent businesses don’t always surface in optimization engines. The algorithm would have delivered something perfectly adequate, two blocks in the other direction, and I would have sat there with excellent wifi and no idea what I’d missed.
This is what optimization systems are built to do. Reduce uncertainty. Surface the most likely best option. Get you to good enough without the friction of not knowing.
And they’re genuinely useful. That’s worth saying clearly. The friction they remove is often real and worth removing.
But sometimes serendipity lives inside friction. It lives in the gap between good enough for anyone and right for you. It depends on the specific, unrepeatable conditions of an ordinary afternoon.
Remove the friction and you remove the gap. Remove the gap and that afternoon becomes a different afternoon entirely. Efficient. Correctly optimized. And entirely unmemorable.
We've built systems that are extraordinarily good at finding what we were already looking for. I've started to wonder about the hidden cost of that precision.
If this resonates with someone in your life, the share button is right below.
Have you ever found a book you weren’t looking for? Walked into a store for one thing and walked out with something that changed the direction of something else entirely.
Most people have a version of this story. The title that caught your eye for no reason you could name. The recommendation from a stranger in an aisle. The afternoon you had no particular plan for, but it’s an afternoon you recall years later.
These moments feel random. They aren’t accidents exactly. They’re what happens when you leave a gap in your day and resist the urge to immediately fill it.
Serendipity doesn’t just connect us to people. It connects us to versions of ourselves we didn’t know were available. The app could have gotten me to a coffee shop. I chose a different path.
Maybe the woman was reading poetry.
The app is very good at finding what it thinks you want.
But some discoveries only happen when you aren’t looking for them.
Stay curious.
