“Debugging: what an odd word. As if "bugging" were the job of putting in bugs, and debugging the task of removing them. But no. The job of putting in bugs is called programming. A programmer writes some code and inevitably makes the mistakes that result in the malfunctions called bugs. Then, for some period of time, normally longer than the time it takes to design and write the code in the first place, the programmer tries to remove the mistakes.”

“I had this idea we would have ordered some good champagne, launched toast after toast to our humanity, which after all had created everything: the opportunities for the bug, the bug itself, and its solution. I think now it might have changed us, softened our failures, made us feel we belonged to—had a true stake in—those lives full of code we had separately stumbled into. I like to think it would have reassured him, saved him: To know that at the heart of the problem was the ancient mystery of time. To discover that between the blinks of the machine’s shuttered eye—going on without pause or cease; simulated, imagined, but still not caught—was life.”

“The corollary of constant change is ignorance. This is not often talked about: we computer experts barely know what we're doing. We're good at fussing and figuring out. We function well in a sea of unknowns. Our experience has only prepared us to deal with confusion. A programmer who denies this is probably lying, or else is densely unaware of himself.”

“At forty, I was too old to work as a programmer myself anymore; writing code is a young person’s job.”

“Beware of bugs in the above code; I have only proved it correct, not tried it.”

“Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?”

“The machine seemed to understand time and space, but it didn’t, not as we do. We are analog, fluid, swimming in a flowing sea of events, where one moment contains the next, is the next, since the notion of “moment” itself is the illusion. The machine—it—is digital, and digital is the decision to forget the idea of the infinitely moving wave, and just take snapshots, convincing yourself that if you take enough pictures, it won’t matter that you’ve left out the flowing, continuous aspect of things. You take the mimic for the thing mimicked and say, Good enough. But now I knew that between one pixel and the next—no matter how densely together you packed them—the world still existed, down to the finest grain of the stuff of the universe. And no matter how frequently that mouse located itself, sample after sample, snapshot after snapshot—here, now here, now here—something was always happening between the here’s. The mouse was still moving—was somewhere, but where? It couldn’t say. Time, invisible, was slipping through its digital now’s.”
