If Another Human Can Do It

Before engineering had a credential, before computers had a career attached to them, before I knew there were other people whose brains worked anything like mine, there was one rule: if another human could do it, there was no reason I could not do it too.

I did not need to know whether I could make the thing. There was no whether. The thing was going to exist. The variables were time, material, tools, information, and how unreasonable I was willing to become before reality finally matched the picture in my head.

At fourteen, one of my favorite books was a sheet-metal engineering book. I do not remember the title. I remember what it taught me. Square-to-round transitions. Rectangle-to-rectangle transitions. Offsets. Layout. The formulas that let a flat sheet become a three-dimensional object.

I loved the math.

At first I practiced with cardboard. I could score one side with a razor blade, bend it cleanly, and turn the drawing into a shape. Eventually cardboard was no longer enough. I did not want to model the transition. I needed to make the transition.

So I found metal.

I was living by the river then, in a place I did not want anyone to find. I traveled by canoe and paid attention to rain because rain erased evidence. I avoided making human-looking trails. If I had to pull a canoe out of the water, I wanted the landing point to be the ugliest, swampiest, thorn-covered, skunk-cabbage-filled place available, because nobody looking at it would think: a person lives through there.

Upstate New York was full of old dairy barns, and some of those barns had collapsed. Their roofing was useful. I would pull pieces of tin from them, carry the metal back to the canoe, paddle it home, flatten it as well as I could, and turn old roofing into sheet-metal transitions.

I did not have proper metalworking tools. I used rocks.

Shale could make a sharp edge, but it was miserable in the hand and broke easily under pressure. Granite was stronger, blunter, heavier, and inconvenient for making a clean score. None of that mattered. A bad tool did not change the answer. It only changed how difficult the implementation was going to be.

If another human can do it, so can I. The only permanent reason I cannot is that I quit.

I made square-to-rounds. I made offsets. I invented transitions just to have another one to solve. I worked half in the dark, crawling around on the ground without sawhorses, scoring old roofing that still carried layers of paint. I had to clean up the paint chips because even the debris could make the camp look inhabited.

Eventually there was a gigantic pile of custom-made ductwork hidden away on a farmer's property. Nobody needed it. Nobody had ordered it. Nobody paid me. There was no career plan attached to it.

I made it because the math existed, therefore the object needed to exist too.

The metal had a price.

Most of my food came from trapping squirrels and chipmunks. Chipmunks were particularly disappointing. They smelled better than they tasted, there was almost nothing on them, and by the time you finished skinning one it cooked in about two seconds. I learned more than I expected about how little usable food is contained in a chipmunk.

Dragging sheets of roofing metal back to camp disturbed the animals. I knew that when I brought tin home, I could scare away what I depended on for food. It might be three days before I trapped anything again.

I brought the metal home anyway.

Then I would spend the next three days working the metal, and after that I might still wait another three days before I ate.

That is how compelling the problem was.

At sixteen came calculus.

I bought a set of old college calculus texts that the bookstore could not sell after the course changed. I loved them. Books had always been more than books to me. They were where I found worlds that were larger, more precise, and more coherent than the one I could see around me.

Eventually engineering became formal. Statics. Dynamics. Mechanics of materials. Chemistry. Physics. Calculus. Problems with known forces, unknown forces, constraints, relationships, and answers that could be derived if I kept working long enough.

I became an Engineer in Training.

The title mattered, but not for the reason a title normally matters. The credential was evidence of something that had started much earlier. Long before I had an engineering book with an examination attached to it, I had already learned the essential behavior: complicated things could be understood. Unknowns could be isolated. Systems could be interrogated. If the answer existed, I could keep working until I found it.

Then I saw C.

That was different.

Until then, I had spent much of my life believing that I was the only person whose brain worked the way mine did. I could speak words and still fail to make myself understood. People used language differently than books used language. The rules seemed to change depending on who was speaking. I had been told often enough that the defect was me that eventually there was almost nothing else to believe.

Then I saw C on a computer screen.

I did not know C. I had never studied it. I had never heard anyone explain it to me.

But I recognized it.

Not the syntax. The logic.

A condition was true or it was not. A loop behaved according to its construction. A variable had a value. Execution followed rules. If something failed, there was a reason. I might not know the reason yet, but the reason existed.

Some other human had made this.

That meant some other human thought this way.

That meant I had people.

I did not discover a programming language. I discovered evidence that minds like mine existed somewhere in the world.

From that moment there was no question about what came next. I had to master C. Not because I wanted a programming job. Not because anyone told me computers were the future. I had spent my life failing to find a language in which another person might understand me, and now one was sitting on a screen.

I decided that if I ever met somebody who knew C, I was going to be an expert. I wanted to be able to have a conversation with a human who understood the same logic. And if I found good, kind people who did not know it yet, I could teach them, and maybe we could speak the same language too.

That changed everything.

The quest never really stopped.

The sheet metal and the calculus and the engineering and the C look like different subjects when they are written on a résumé.

They were never different subjects to me.

They were all the same pursuit: find the structure, understand the relationships, locate the unknown, make the thing work.

That is still what happens when my brain locks onto a project now. I do not wonder whether I will solve it. I do not spend much time negotiating with the possibility of defeat. I assume the answer exists and begin removing the things standing between me and it.

Sometimes that has looked unreasonable from the outside.

At fourteen, it looked like hauling barn roofing through the woods and going hungry so I could fabricate ductwork nobody needed.

Later, it looked like calculus books, engineering examinations, construction sites, custom computers, programming languages, and systems large enough to consume years of a life.

The tools changed.

The proposition did not.

If another human can do it, there is no reason I cannot do it too.
The only question is how long reality intends to argue with me before it gives in.
