His beer arrived. He took it from the waitress’s hand before she’d had a chance to set it down and drank a deep gulp. ‘Right. Your question. We’re examining human organs, and in particular the human brain, trying to understand better their pathways of evolution to our present state, and how much further evolution will change them in the future.’
’And you are hoping one of the results will be to lead you to understand what human consciousness is?’
‘Exactly.’
‘Is Neural Darwinism a way to describe your simulation programs?’
‘That’s Edelman’s phrase.’ He drank some more beer. ‘No, there’s quite a difference.’ A smear on the right lens of his glasses was irritating him. He took them off and wiped them with his handkerchief. ‘You must have covered this field at Tulane. Neural Darwinism relates to when you build a robot that doesn’t actually have a program – it has to learn from its experiences, the way human beings do. That’s taking steps towards building thinking machines by copying some of the ways human brains work. We’re not doing that – our field is different.’
He held his glasses up to the light and still wasn’t satisfied. Wiping them some more, he said, ‘Our methodology is to simulate millions of years of evolution in our computers, making virtual replicas of primitive brains and seeing if, by replicating natural selection, we can arrive at far more complex models that are closer to our own brains. At the same time we make virtual models of current human brains and let them keep evolving way into the future.’
‘I’m puzzled by something there, Dr Klaesson.’
‘Call me John.’
‘John, OK, thanks. You say you make virtual replicas of primitive brains?’
‘That’s correct.’
‘How primitive, John? How far are you going back? Palaeolithic? Jurassic? Cambrian?’
‘Before then, even. Right back to Archaean.’
The third beer was kicking in now. He noticed to his surprise he had drunk nearly two thirds of it. He knew he had to slow down, but it was really making him feel good.
‘And when you do finally understand how the human brain was formed, then you’ll understand consciousness?’
‘Not necessarily – you’re making a big leap there.’
‘Oh, right.’ She was grinning and her voice was cynical. ‘You’re going to switch off your computer one day and say, Hey, I just finally figured out how the human brain was formed. Now I’m going to go home and feed the cat. Is that it?’
John smiled back.
‘From the way you work, for you to have figured out how the brain was formed, you’d have a virtual model of it in your computer. Then the next step is going to be improving it, right? What will you do – add on more memory? Some kind of interface with humans?’
‘Whoa! You’re going too fast.’
‘I’m not, Dr Kl- John, I’m just quoting from a paper you published three years ago.’
He nodded, remembering now. ‘Ah yes, OK.’ He smiled. ‘You’ve done your homework – but that wasn’t the theme of the paper – I was hypothesizing.’ He was getting concerned suddenly that this interview was heading the wrong way. He needed to get a grip and steer it. ‘Listen, this speculation about the future – I’m happy to talk about it, but could we keep that whole area off the record?’
‘Hi, how you folks doing? Get you some more drinks?’ The waitress had suddenly materialized and was standing beside him.
John saw that the reporter’s glass was almost empty. ‘Sure,’ he said. ‘Sally – another one?’
She hesitated a moment. ‘How’s your time? I’m not keeping you too long?’
He glanced at his watch. Half seven. Naomi wouldn’t be home until after nine, she’d told him. ‘I’m fine,’ he said.
‘OK, I’ll have another Chardonnay.’
John considered his empty glass for a moment. As a student in Sweden he could easily manage upwards of half a dozen of these – and stronger beer too. ‘Same again – I’ll live dangerously!’
Sally reached forward and pressed the stop button on the tape machine. ‘Off the record for a few minutes – tell me what you feel about the future – I’m really fascinated.’
He would never know why he said it – whether it was the alcohol that had lowered his guard, or whether it was the thought that if he opened up to her a little, he might get a better piece from her – or whether it was just the natural action of a man to show off to a woman who seemed genuinely interested. Or whether it was simply the release of stuff bottled up in him for too long. In any event, he felt comfortable; she was a friend of Naomi’s. He could trust her.
‘Designer babies are the future,’ he said.
‘Like – cloning?’
‘No, not cloning. I mean selecting the genes that your child will have.’
‘To what end?’
‘To enable man to take control from Mother Nature – to be in a position so we can steer our future evolution to our needs. So that we can be looking at a human lifespan of hundreds of years, if not thousands, rather than a meagre three score years and ten.’
‘I’m very uncomfortable with that whole notion of designer babies,’ she said. ‘I’m sure it’s going to happen but I find it scary. How many years do you reckon before it starts happening – I mean, like, before it’s possible. Ten?’
‘It’s possible now.’
‘I don’t believe that,’ she said. ‘Not from what I’ve heard. Not from anyone I’ve talked to.’
The alcohol was kicking in now and he felt good in the company of this increasingly attractive woman, and he really felt relaxed, perhaps too relaxed. All this secrecy had been hard; surely it wouldn’t hurt talking to Naomi’s friend? He glanced at the tape recorder. The tell-tale red light was not showing. ‘We’re off the record? Strictly off the record, right?’
‘Totally.’
With a smile he said, ‘You’re not talking to the right people.’
‘So who should I be talking to?’
He tapped his chest. ‘Me.’

The building was moving. Definitely. For a moment, as the floor rose up beneath him, John thought he was back on the Serendipity Rose . Then the wall came in towards him, clouting him on the shoulder, sending scalding black coffee slopping out of the cup he was holding and onto his hand, his clothes and the floor.
He staggered sideways, everything in front of him blurry. He had to sober up, somehow. He’d been all right in the bar, he’d been fine there, no problem, it was the walk in the cold fresh air outside that had done it.
A chunk of time was missing. There was a blank from when he went into the bar to now, walking down the corridor towards his office. He couldn’t remember saying goodbye to the reporter. When had she gone?
How much did I drink?
It hadn’t been that much, surely? Just a few beers – then he’d moved on to whisky on the rocks. Just a couple of whiskies, just enough to relax him, that was all. Christ. Empty stomach, that was the problem, he realized. Skipped lunch after seeing Dr Rosengarten. It was now – he looked at his watch – ohmygod – almost a quarter after ten. He’d been with the reporter for over three hours. Not like I was having an affair or anything. I was only talking to the woman. Trying to get her to write a good piece, one that would help me get funding – that’s all I was doing.
Except. Something dark inside his head was stalking him, something elusive was shadow-boxing him, taunting him. It was the sense that something was wrong, that he had made a terrible error. He hadn’t made a pass at her, nothing as crass as that – although he had some memory of escorting her to the car park and some clumsy clashing of their lips when she’d suddenly darted her head forward to kiss his cheek, he had thought.
But that wasn’t what was worrying him.
He unlocked his door, switched the light on and put the cup, which was now less than half full, on his desk, and sat down more heavily than he had intended, sending his chair trundling back on its castors.
He checked his voice mail, and there was a message from Dr Rosengarten, received at ten to seven, the curt nasal voice of the obstetrician informing him he was returning his call, and was about to leave his office for the day.
