“But that’s all analog,” she continued. “It’s all about that one piece of frozen meat. You only get one chance to reanimate it. Best to wait until you’re sure it’ll work. Instead now we’ve got an opportunity to do this digitally. And that opportunity has come along within living memory of Uncle Richard himself.” Sophia’s voice got a little husky at this point, as she was clearly remembering her vague little-kid memories of sitting on Dodge’s lap. She cleared her throat. “So I want to work on that. And I don’t claim that I’m going to come up with the answer to it all during one summer’s worth of work, but to me it feels like exploring it is a worthwhile project, and being a member of the family—someone who knew him when I was a little girl—gives me a kind of standing that nobody else has.”

Zula’s eyes were shining, out of some combination of maternal pride in her daughter and grief for her uncle. “Sophia,” she said, “I have to ask you something. When you went off to college, your major was undeclared. But you were pretty sure it was going to be comparative religion or classics or something in that vein. That’s mostly what you studied in your freshman year. But after that you turned pretty decisively in the direction of cognitive science, neurology, computer science.”

Sophia was nodding, slightly impatient. “Those are just more technical ways of getting at the same questions.”

“I understand that, honey. But I have to know, just for my own curiosity: how long have you been thinking about this? The conversation we’re having right now, in my office: is it something you’ve been planning for years?”

Sophia shook her head. “Months, maybe. I mean, sure, my interest in neuroscience was piqued by all the exposure I had while I was growing up to dinner-table conversations about what you and C-plus and the others were up to concerning DB. But, the idea of actually digging into that thing and running some code? That wasn’t even on the table, technically speaking, until Hole in the Wall came online.”

“I kind of know what that is,” Marcus said. “The latest and greatest processor farm. But you’re going to have to help me out a little.”

“It’s at a place about a hundred miles from here called Hole in the Wall Coulee—an inlet on the Columbia River. Coincidentally, just a little downstream of Ephrata. They built it on the site of an old aluminum plant. So it’s got cheap juice and cold water.”

“Data centers are all over that part of the state,” Marcus pointed out. “Have been for decades. What makes Hole in the Wall a game-changer for DB?”

“It’s the first one exclusively built around quantum computers.”

“And you think that quantum computers are better at simulating brain processes?” The skepticism in Marcus’s voice was gentle but unmistakable.
