Middle School now, where Carl was just finishing grade eight. "But what's Y2K got to do with the aliens not signaling their existence?" she asked.
    "Maybe they understand how dangerous it would be for us to know that some races did manage to survive technological adolescence. We got through Y2K because of lots of really hard work by really dedicated people, but once we were through it, we assumed that we would have gotten through it regardless . Surviving into the year 2000 was taken as—what was your phrase?—'an existence proof' that such survival had been inevitable. Well, detecting alien races who've survived technological adolescence would be taken the same way. Instead of us thinking it was very difficult to survive the stage we're going through, we'd see it as a Cakewalk. They survived it, so surely we will, too." Don paused. "Say some alien, from a planet around—well, what's a nearby sunlike star?"
    "Epsilon Indi," said Sarah.
    "Fine, okay. Imagine aliens at Epsilon Indi pick up the television broadcasts from some other nearby star, um..."
    "Tau Ceti," she offered.
    "Great. The people at Epsilon Indi pick up TV from Tau Ceti. Not that Tau Ceti was deliberately signaling Epsilon Indi, you understand; they're just leaking stuff into space. And Epsilon Indi says, hey, these guys have just emerged technologically, and we did that long ago; they must be going through some rough times—maybe the guys on Epsilon Indi can even tell that from the TV signals. And so they say, let's contact them so they'll know it's all going to be okay. And what happens? A few decades later Tau Ceti falls silent. Why?"
    "Everybody there got cable?"
    "Funny," said Don. "Funny woman. No, they didn't all get cable. They just stopped worrying about somehow surviving having the bomb and all that, and now they're gone , because they got careless. You make that mistake once—you tell a race, hey, look, you can survive, 'cause we did—and that race stops trying to solve its problems. I don't think you'd ever make that mistake again."
    They'd come to Churchill Avenue, and had turned east, walking by the public school Emily, who was now in grade two, attended. "But they could tell us how they survived, show us the answer," said Sarah.
    "The answer is obvious," said Don. "You know the least-best-selling diet book of all time? Losing Weight Slowly by Eating Less and Exercising More ."
    "Yes, Mr. Atkins."
    He made his tone one of mock umbrage. "Excuse me! Going for a walk here! Besides, I am eating less, and more sensibly, way more sensibly than I was before I started cutting back on carbs. But you want to know what the difference is between me and all the others who lost weight quickly on Atkins, then put it back on as soon as they quit? It's been four years now, and I haven't quit—and I'm never going to. That's the other piece of weight-loss advice no one wants to hear. You can't diet temporarily; you have to make a permanent lifestyle change. I have, and I'm going to live longer for it. There are no quick fixes for anything."
    He ceased talking as they crossed Claywood, then began speaking again. "No, the answer is obvious. The way to survive is to stop fighting each other, to learn tolerance, and to put an end to the huge disparity between rich and poor, so that some people don't hate the rest of us so much that they'd do anything, including even killing themselves, to hurt us."
    "But we need a quick fix," said Sarah. "With terrorists having access to biotech and nuclear weapons, we can't just wait for everyone to get enlightened. You have to solve the problem of high-tech terrorism really quickly—just as soon as it becomes a problem—or no one survives. Those alien races who have survived must have found a solution."
    "Sure," said Don. "But even if they did tell us their answer, we wouldn't like it."
    "Why?"
    "Because," he said, "the solution is that time-honored sci-fi cliche, the hive mind. On Star Trek , the reason the Borg absorb
