The Dart
When I was five years old, a dart went through my right eye.
I don't remember the throw. Children don't remember the moments that change their lives — they remember the moments after. I remember the hospital ceiling, which was white and had a water stain shaped like a boot. I remember my mother's voice, which was steady in a way that I now understand, forty-seven years later, means she was out of her mind with terror and holding it together for me. I remember the warmth of her hand on my arm in the dark — not squeezing, just there, the way you hold something you're afraid of losing.
And I remember the moment, weeks later, when a nurse peeled the patch off and the world came back wrong.
Flat. Missing a dimension I hadn't known existed until it was gone.
Depth perception is something you never think about until half the input is missing. The glass on the table looks like it's here but it's actually there — four inches to the left, just out of reach of the hand that thought it knew where things were. The curb isn't where it appears. The ball isn't where it seems. Your brain is lying to you, confidently, with the full authority of a visual system that used to have two reference points and now has one. And the lie is invisible, because the brain doesn't label its reconstructions. It presents them as fact.
I had to relearn where things were. At five years old, I developed a relationship with perception that most people never need — the understanding, lodged in my body before I had words for it, that what I see is not the thing itself. It is my best guess at the thing. A reconstruction, assembled from partial data, presented as certainty by hardware that would rather be wrong with confidence than honest about its gaps.
I was five. I adapted. Children adapt — it is their one reliable superpower. But the adaptation left something behind: a permanent skepticism about surfaces. If your right eye was rebuilt from the inside out, you learn young that the visible world is a draft, not a final version. You learn to check. You learn to reach slowly. You learn to ask the question that Plato would name twenty-four centuries before you were born: what if what I'm seeing is not the thing itself?
"Begin the morning by saying to thyself, I shall meet with the busy-body, the ungrateful, arrogant, deceitful, envious, unsocial."
— Marcus Aurelius, Meditations, Book II.1 (George Long translation, 1877)
Marcus Aurelius wrote that in a military tent on the Danube frontier during the Marcomannic Wars — the campaign he spent the last decade of his life fighting, far from Rome, in the rain and the cold, while plague swept through his legions. He was the most powerful man on earth. His soldiers were dying. His co-emperor Lucius Verus had already died. His general Avidius Cassius would later declare himself emperor while Marcus was still alive. And in the morning, before he faced any of it, Marcus wrote himself a note: today will be difficult. People will disappoint you. Prepare your response before the stimulus arrives.
I didn't read Marcus until I was forty. By then, I had been living his method for thirty-five years without knowing it had a name. When half your vision is a reconstruction, you learn early that preparation is not paranoia — it's how you keep from walking into walls. You anticipate the lie before it arrives. You build the correction before you need it.
This is not pessimism. It is engineering. And if you've ever been blindsided by something you should have seen coming — a layoff, a betrayal, a diagnosis — you already know why this chapter matters. Stay with me. I'm showing you how the scars became the architecture.
The Data Center
My father was a mainframe systems lead operator for Alcoa. I grew up in a data center.
Not metaphorically. The physical room. The raised floor tiles, cold from the air conditioning, the kind of cold you could feel through your sneakers. The humming of the tape drives — a low, co
