"What does an Asimovist have to do, besides following the three laws?" There were lots of rumors about this, but Robbie had always discounted them.
"You have to tithe one cycle in ten to running missionaries for the cause. Participate in the message boards, if you’d like. Most importantly, you have to pledge to stay alive and aware. You can slow yourself down if you want, but you can’t switch off. Not ever. That’s the Asimovist pledge—it’s the third law embodied."
"I think that the third law should come first," Robbie said. "Seriously."
"That’s good. We Asimovists like a religious argument."
Olivaw let Robbie delete him that night, and he emailed the diffs of Olivaw’s personality back to Olivaw’s version control server for him to reintegrate later. Once he was free of Olivaw, he had lots of processor headroom again, and he was able to dial himself up very hot and have a good think. It was the most interesting night he’d had in years.

"You’re the only one, aren’t you?" Kate asked him when she came up the stairs later that night. There was clear sky and they were steaming for their next dive-site, making the stars whirl overhead as they rocked over the ocean. The waves were black and proceeded to infinity on all sides.
"The only what?"
"The only one who’s awake on this thing," Kate said. "The rest are all—what do you call it, dead?"
"Nonconscious," Robbie said. "Yeah, that’s right."
"You must go nuts out here. Are you nuts?"
"That’s a tricky question when applied to someone like me," Robbie said. "I’m different from who I was when my consciousness was first installed, I can tell you that."
"Well, I’m glad there’s someone else here."
"How long are you staying?" The average visitor took over one of the human shells for one or two dives before emailing itself home again. Once in a long while they’d get a saisoneur who stayed a month or two, but these days, they were unheard-of. Even short-timers were damned rare.
"I don’t know," Kate said. She dug her hands into her short, curly hair, frizzy and blonde-streaked from all the salt water and sun. She hugged her elbows, rubbed her shins. "This will do for a while, I’m thinking. How long until we get back to shore?"
"Shore?"
"How long until we go back to land."
"We don’t really go back to land," he said. "We get at-sea resupplies. We dock maybe once a year to effect repairs. If you want to go to land, though, we could call for a water taxi or something."
"No, no!" she said. "That’s just perfect. Floating forever out here. Perfect." She sighed a heavy sigh.
"Did you have a nice dive?"
"Um, Robbie? An uplifted reef tried to kill me."
"But before the reef attacked you." Robbie didn’t like thinking of the reef attacking her, the panic when he realized that she wasn’t a mere human shell, but a human.
"Before the reef attacked me, it was fine."
"Do you dive much?"
"First time," she said. "I downloaded the certification before leaving the noosphere along with a bunch of stored dives on these sites."
"Oh, you shouldn’t have done that!" Robbie said. "The thrill of discovery is so important."
"I’d rather be safe than surprised," she said. "I’ve had enough surprises in my life lately."
Robbie waited patiently for her to elaborate on this, but she didn’t seem inclined to do so.
"So you’re all alone out here?"
"I have the net," he said, a little defensively. He wasn’t some kind of hermit.
"Yeah, I guess that’s right," she said. "I wonder if the reef is somewhere out there."
"About half a mile to starboard," he said.
She laughed. "No, I meant out there on the net. They must be online by now, right? They just woke up, so they’re probably doing all the noob stuff, flaming and downloading warez and so on."
"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.
