Mitch folded his hands and nodded patiently. 'I understand all this,' he said. 'Get to the point, will you?'
'All right then, the point is this: it seems — '
'Seems?' said Beech. 'There's no seems about it, man. It's a goddamn fact.'
'It appears that Abraham has already begun his own self-replication program. Which means — '
'Which means,' said Mitch, 'that he's taking account of an entirely irrelevant occupancy. Namely ourselves. Not the Yu Corporation, like he's supposed to.'
'I told you Mitch would understand,' said Beech to Yojo.
'That's it exactly,' said Kenny. 'I mean, there's no point in Abraham evolving into a higher level of fitness and siring Isaac if he's only been dealing with us and a few goddamned workmen.'
'But this is what has happened?' said Mitch. 'Isaac is already in existence?'
Aidan Kenny nodded unhappily.
'And what does Abraham himself have to say about it?' asked Mitch.
'That's a joke, right?' said Beech.
'I don't know,' shrugged Mitch. 'You tell me.'
Bob Beech grinned and brushed up his formidable moustache with an outstretched forefinger and thumb.
'Hey, we're the best, but we're still in the twentieth century, Mitch,' he said. 'An explanation implies an understanding.'
'Not if you frame the question correctly,' argued Mitch.
'Yeah, it's a nice idea,' said Hideki Yojo. 'If only things were that sophisticated. We're doing well just to have improved on the old binary logic — true or false, y'know? Fuzzy logic encompasses binary logic but allows for the scenario which says that something might have partial membership of two separate sets.'
'So that something might be partly true, or partly false.'
'That's right. Or true given certain conditions.'
'I read something about that,' said Mitch. 'Wasn't there something about how a computer should define a penguin?'
'Oh, that.' Beech looked bored and nodded. 'Yeah, a conventionally programmed computer knows that birds fly. But when told that penguins cannot fly it insists that a penguin is not a bird. Fuzzy logic computers get around this difficulty by accepting that most if not all birds can fly.'
'Similarly,' said Aidan Kenny, 'with regard to systems management control, the fuzzy controller — in this case Abraham — permits some interpolation between sensor data classes.'
'Look,' said Yojo, 'can we please stop using that word "fuzzy" and use the proper term? It drives me nuts. This is an adaptive analog we're talking about. Mitch, the idea is that it's similar to what a human brain does in that it favours adaptation over precision and uses relative not absolute values. OK?'
'Look guys,' interjected Kenny, 'what we need to discuss — '
'There must have been a problem with defuzzification,' continued Beech and seeing Yojo's display of disgust and irritation, he gave him the finger. 'Some kind of collapse of the output fuzzy distribution into a single value — '
'You asshole — '
'- and — and that value must have distorted Abraham's interpretation of the fuzzy output.'
'What we really need to discuss,' said Kenny, raising his voice, 'is what the hell we're going to do about it.'
'Amen, brother,' said Yojo.
They seemed to be waiting for Mitch to say something. He shrugged. 'I don't know. You're the engineers, I'm just the architect. What do you suggest?'
'Well obviously there are going to be a few risks attaching to whatever we do,' said Kenny warningly.
'What kind of risks are we talking about here?'
'Expensive risks,' cackled Yojo.
'We never took an SRS off-line before,' said Beech. 'We're not exactly sure what'll happen.'
'The thing is, Mitch,' said Kenny. 'We hadn't even ceded full control of the building to Abraham yet. So in a way we can't run and test all the building management systems properly until we shut down the offspring: namely, Isaac.'
'Speaking for myself,' said Beech, 'I'd like to leave things as they are for just a while longer and see how they play out. This is interesting. I mean, it could be important not just for your building management systems, but for the future of the Yu-5-'
'The trouble with that scenario,' said Yojo, 'is that you risk sterility for Abraham. And the longer you put it off, the greater the risk becomes.'
'On the other hand,' argued Beech, 'you shut down Isaac and you run the risk that Abraham might not be able to generate another offspring program. Not without building the whole MPPS up from scratch again.'
'And you want me to decide this?' said Mitch.
'Yeah, I guess we do.'
'C'mon guys, King Solomon I'm not.'
'Cut the baby in half!' laughed Yojo. 'What a great idea.'
'We were kind of hoping you might help us decide,' said Kenny.
'But what if I decide wrong?'
Kenny shrugged.
'What I mean is, how much. What's the possible cost of the wrong decision?'
'$40 million,' said Yojo.
'Yeah, take your time there, guy,' said Beech.
'Come on,' protested Mitch, 'You're not serious. I can't decide something like this.'
'Technical coordination, Mitch,' said Aidan Kenny, 'that's what we need. A little coordination. Some executive guidance.'
Mitch stood up and walked around behind Kenny's son. The boy was still playing his game, oblivious of the discussion around him, his face myopically close to the enormous screen as he twisted the analog joystick one way and then the other. Mitch watched the game for a moment, trying to fathom its purpose. It was hard to understand precisely what was happening. The game seemed to involve Michael negotiating a gun-toting space commando through an underground city. From time to time one of an apparently endless variety of hideouslooking creatures came through a door, or arrived in an elevator, or dropped through a hole in the roof, and tried to kill the protagonist. At this point a fierce fire fight would commence. Mitch watched as Michael's thumb, furiously depressing a button on the top of the joystick, activated a chainsaw fire-throwing gun and blasted the most recently arrived creature to all four corners of the screen. The graphics were superb, Mitch thought. Damage inflicted on the creatures looked extremely realistic. A little too realistic for Mitch's taste: a large section of the creature's intestines splattered against the screen and then slid slowly away, leaving a wide trail of blood. He picked up the box that had contained the CD-ROM and read the copy. The game was called Escape from the Citadel. There were other similarly violent games in a carrier bag by the boy's feet. Doom II. The Eleventh Hour. Intruder. In all, about two or three hundred dollars' worth. Mitch wondered if any of them were suitable for a child of Michael's age. He turned away. It was probably none of his business.
He shook his head, wondering if the game he was playing with these three men was really so very different. Certainly Alison would not have thought so: she thought that smart buildings were inherently absurd. What was it she said. The bigger the boys, the bigger the toys? For the moment Mitch was disposed to think that she might be right as he glanced at the three computer experts.
'OK, look, my decision is this,' he said finally. 'You're the goddamn experts. You decide. Take a vote on it or something. I'm not sufficiently informed on this one.' He nodded firmly. 'That's my decision. Vote. What do you say?'
