Everything was flowing. Then it stopped.
The software crashes mid-presentation. The word you always knew suddenly looks wrong on the page. The road you drive every day is closed. For a moment you’re suspended, neither here nor there, and in that suspension something unusual happens.
You think.
Not the background processing that runs your fluency. Actual deliberate attention. The invisible becomes visible. What was ready-to-hand snaps into present-at-hand, and in that snap, that’s what Heidegger called breakdown.
Breakdown isn’t failure. Breakdown is the moment the structure of your situation becomes visible. For one brief window, you can see the assumptions you were operating inside.
This is why breakdown is generative, not just disruptive.
When the hammer works, you learn nothing about hammering. When it breaks, you learn everything, the weight distribution, the grip, what the wood grain is doing, why the nail bent. The breakdown reveals the background that was always there, running silently beneath your fluency.
Winograd and Flores saw that this is how humans develop genuine understanding. Not through instruction alone. Through encountering resistance. Through the moment when the world pushes back and forces articulation of what was previously unspoken.
This is also why you can’t fully teach expertise. You can transmit information. But the background, the felt sense, the judgment, the knowing-in-use, that only develops through accumulated breakdown. Through having things fail on you, repeatedly, in contexts where it mattered.
A surgeon learns through complications. A musician learns through the note that didn’t land. A programmer learns through the bug that shouldn’t exist.
The breakdown is the curriculum.
Here’s what Flores couldn’t have fully anticipated but we’re now living,
We’ve built tools that eliminate breakdown from the learning sequence.
AI generates the code. It mostly works. You never hit the resistance that would have taught you the underlying structure. The breakdown that would have been your curriculum never arrives, until it arrives catastrophically, at scale, in production, when you have no background to draw on because you were never required to build one.
We didn’t just automate a task. We automated the failure mode that was doing the teaching.
And a system that can’t break down in ways you can learn from isn’t a better tool. It’s a more dangerous one.
