“What about the experimental treatment the doctor mentioned?” said Nektar, looking down at her son, a little frown in her smooth brow. “The nants,” she continued. “Why wouldn’t you let me tell the doctor that you work for Nantel, Ond? I think you bruised my shin.” The doctor had suggested that a swarm of properly programmed nants might eventually be injected into Chu to find their way to his brain and coax the neurons into growing the missing connections.

Ond’s oddball boss, Jeff Luty—annoyingly a bit younger than Ond—had built his company, Nantel, into a major player in just five years. Luty had done three years on scholarship at Stanford, two years as a nanotech engineer at an old-school chip company, and had then blossomed forth on his own, patenting a marvelously ingenious design for growing biochip microprocessors in vats. The fabulously profitable and effective biochips were Nantel’s flagship product, but Luty believed the future lay with nants: a line of bio-mimetic self-reproducing nanomachines that he’d patented. For several months now, Nantel had been spreading stories about nants having a big future in medical apps.

“I don’t like arguing tech with normals,” said Ond, still carrying Chu in his arms. “It’s like mud-wrestling a cripple. The stories about medical nant apps are hype and spin and PR, Nektar. Jeff Luty pitches that line of bullshit so the feds don’t outlaw our research. Also to attract investors. Personally, I don’t think we’ll ever be able to program nants in any purposeful, long-lasting, high-level way, even though Luty doesn’t want to admit it. All we can do is give the individual nants a few starting rules. The nant swarms develop their own Wolfram-irreducible emergent hive-mind behaviors. We’ll never really control the nants, and that’s why I wouldn’t want them to get at my son.”

“So why are you even making the stupid nants?” said Nektar, an edge in her voice. “Why are you always in the lab unless I throw a fit?”

“Jeff has this idea that if he had enough nants, he could create a perfect virtual world,” said Ond. “And why does he want that? Because his best friend died in his arms when he was a senior in high school. Jeff confides in me; I’m an older-brother figure. The death was an accident; Jeff and his friend were launching a model rocket. But deep down, Jeff thinks it was his fault. And ever since then, he’s been wanting to find a way to bring reality under control. That’s what the nants are really for. Making a virtual world. Not for medicine.”
