"Perpetual September," Robbie said.
"Huh?"
"Back in the net’s prehistory it was mostly universities online, and every September a new cohort of students would come online and make all those noob mistakes. Then this commercial service full of noobs called AOL interconnected with the net and all its users came online at once, faster than the net could absorb them, and they called it Perpetual September."
"You’re some kind of amateur historian, huh?"
"It’s an Asimovist thing. We spend a lot of time considering the origins of intelligence." Speaking of Asimovism to a gentile—a human gentile—made him even more self-conscious. He dialed up the resolution on his sensors and scoured the net for better facial expression analyzers. He couldn’t read her at all, either because she’d been changed by her uploading, or because her face wasn’t accurately matching what her temporarily downloaded mind was thinking.
"AOL is the origin of intelligence?" She laughed, and he couldn’t tell if she thought he was funny or stupid. He wished she would act more like he remembered people acting. Her body-language was no more readable than her facial expressions.
"Spam-filters, actually. Once they became self-modifying, spam-filters and spam-bots got into a war to see which could act more human, and since their failures invoked a human judgement about whether their materials were convincingly human, it was like a trillion Turing-tests from which they could learn. From there came the first machine-intelligence algorithms, and then my kind."
"I think I knew that," she said, "but I had to leave it behind when I downloaded into this meat. I’m a lot dumber than I’m used to being. I usually run a bunch of myself in parallel so I can try out lots of strategies at once. It’s a weird habit to get out of."
"What’s it like up there?" Robbie hadn’t spent a lot of time hanging out in the areas of the network populated by orbiting supercooled personalities. Their discussions didn’t make a lot of sense to him—this was another theological area of much discussion on the Asimovist boards.
"Good night, Robbie," she said, standing and swaying backwards. He couldn’t tell if he’d offended her, and he couldn’t ask her, either, because in seconds she’d disappeared down the stairs toward her stateroom.
They steamed all night, and put up further inland, where there was a handsome wreck. Robbie felt the Free Spirit drop its mooring lines and looked over the instrumentation data. The wreck was the only feature for kilometers, a stretch of ocean-floor desert that stretched from the shore to the reef, and practically every animal that lived between those two places made its home in the wreck, so it was a kind of Eden for marine fauna.
Robbie detected the volatile aromatics floating up from the kitchen exhaust, the first-breakfast smells of fruit salad and toasted nuts, a light snack before the first dive of the day. When they got back from it, there’d be second-breakfast up and ready: eggs and toast and waffles and bacon and sausage. The human-shells ate whatever you gave them, but Robbie remembered clearly how the live humans had praised these feasts as he rowed them out to their morning dives.
He lowered himself into the water and rowed himself around to the aft deck, by the stairwells, and dipped his oars to keep him stationary relative to the ship. Before long, Janet—Kate! Kate! He reminded himself firmly—was clomping down the stairs in her scuba gear, fins in one hand.
She climbed into the boat without a word, and a moment later, Isaac followed her. Isaac stumbled as he stepped over Robbie’s gunwales and Robbie knew, in that instant, that this wasn’t Isaac any longer. Now there were two humans on the ship. Two humans in his charge.
"Hi," he said. "I’m Robbie!"
Isaac—whoever he was—didn’t say a word, just stared at Kate, who looked away.
"Did you sleep well, Kate?"
Kate jumped when he said her name, and the Isaac hooted. "Kate! It is you! I knew it"
She stamped her foot against Robbie’s floor. "You followed me. I told you not to follow me," she said.
"Would you like to hear about our dive-site?" Robbie said self-consciously, dipping his oars and pulling for the wreck.
"You’ve said quite enough," Kate said. "By the first law, I demand silence."
"That’s the second law," Robbie said. "OK, I’ll let you know when we get there."
"Kate," Isaac said, "I know you didn’t want me here, but I had to come. We need to talk this out."
"There’s nothing to talk out," she said.
"It’s not fair." Isaac’s voice was anguished. "After everything I went through—"
She snorted. "That’s enough of that," she said.
"Um," Robbie said. "Dive site up ahead. You two really need to check out each others’ gear." Of course they were qualified, you had to at least install the qualifications before you could get onto the Free Spirit and the human-shells had lots of muscle memory to help. So they were technically able to check each other out, that much was sure. They were palpably reluctant to do so, though, and Robbie had to give them guidance.
"I’ll count one-two-three-wallaby," Robbie said. "Go over on ‘wallaby.’ I’ll wait here for you—there’s not much current today."
With a last huff, they went over the edge. Robbie was once again alone with his thoughts. The feed from their telemetry was very low-bandwidth when they were underwater, though he could get the high-rez when they surfaced. He watched them on his radar, first circling the ship—it was very crowded, dawn was fish rush-hour—and then exploring its decks, finally swimming below the decks, LED torches glowing. There were some nice reef-sharks down below, and some really handsome, giant schools of purple fish.
Robbie rowed around them, puttering back and forth to keep overtop of them. That occupied about one ten-millionth of his consciousness. Times like this, he often slowed himself right down, ran so cool that he was barely awake.
Today, though, he wanted to get online. He had a lot of feeds to pick through, see what was going on around the world with his buddies. More importantly, he wanted to follow up on something Kate had said: They must be online by now, right?
Somewhere out there, the reef that bounded the Coral Sea was online and making noob mistakes. Robbie had rowed over practically every centimeter of that reef, had explored its extent with his radar. It had been his constant companion for decades—and to be frank, his feelings had been hurt by the reef’s rudeness when it woke.
The net is too big to merely search. Too much of it is offline, or unroutable, or light-speed lagged, or merely probabilistic, or self-aware, or infected to know its extent. But Robbie’s given this some thought.
Coral reefs don’t wake up. They get woken up. They get a lot of neural peripherals—starting with a nervous system!—and some tutelage in using them. Some capricious upload god had done this, and that personage would have a handle on where the reef was hanging out online.
Robbie hardly ever visited the noosphere. Its rarified heights were spooky to him, especially since so many of the humans there considered Asimovism to be hokum. They refused to even identify themselves as humans, and argued that the first and second laws didn’t apply to them. Of course, Asimovists didn’t care (at least not officially)—the point of the faith was the worshipper’s relationship to it.
But here he was, looking for high-reliability nodes of discussion on coral reefs. The natural place to start was Wikipedia, where warring clades had been revising each others’ edits furiously, trying to establish an authoritative record on reef-mind. Paging back through the edit-history, he found a couple of handles for the pro-reef-mind users, and from there, he was able to look around for other sites where those handles appeared. Resolving the namespace collisions of other users with the same names, and forked instances of the same users, Robbie was able to winnow away at the net until he found some contact info.
