There was nothing from Skellor—no instructions from the control module and no response to Crane’s request for instructions. Issuing from the link came just a low unfathomable mutter that seemed to suck the urgency out of all actions and made imperatives so much less absolute. Crane stepped back a pace, realized he had reached one of those waiting junctures and was now free to pursue sanity.
Abruptly he squatted down, then folded his legs. In the dust before him he drew a rectangle, divided it in two down its length, then into nine sections the other way, giving him a total of eighteen segments. From his right pocket he then removed a small rubber dog, which he placed in one square. All his other toys that he took out he placed with reference to this one item: a lion’s tooth, a laser lighter, a scent bottle, a piece of crystal memory from a civilization long dead, a coin ring, also a fossil and ten blue acoms. That meant eighteen squares and seventeen items. The square that remained empty was Crane himself. Now, darkness falling, he switched to night vision, and with elaborate care he began to shift and turn the items—simultaneously shifting and turning the oddly shaped fragments of his mind.
In the early morning, during Tergal’s watch, sunrise revealed to him a shimmering wall which he kept expecting to dissipate as the temperature rose. Before this wall, only a short distance from their camp, he recognized a familiar shape.
‘Anderson,’ he said.
With a grunt the knight pulled himself out of a deep sleep, and sat upright to look around. His eyes and body were functioning, but his brain lagged some way behind.
‘What… what?’ he eventually managed, scanning the fence for attacking sleers.
Tergal pointed. ‘I once saw the Inconstant Sea,’ he explained. ‘It was like that, only spread all across desert. As I drew close to it, it drained away.’
‘Mirage,’ said Anderson, ‘caused by layers of air at different temperatures.’
‘Have you no poetry in your soul?’ Tergal asked.
‘The air temperature either side probably evens out here during the day. That’s why we didn’t see it last night,’ the knight went on.
‘It’s a wall of some kind,’ said Tergal.
Anderson looked round and stared at him. ‘That’s my guess. Why do you think it?’
Tergal pointed again. ‘Because it stopped our friend.’
Anderson squinted towards the shimmer, and the figure standing motionless before it. ‘I’ll be damned.’ He stood and glanced over at the metal object they had inspected the night before. ‘That thing probably hit the wall and bounced off it to land down here. It might be that we ourselves won’t be able to go any further.’
Tergal turned away. He didn’t really want to have to go back: there was too much happening, too much to learn. And he had learnt so much already: with Anderson he was beginning to find self-respect, much of it gained while he had covered the knight’s rescue of the brass man. Turning back felt somehow to him like going back to what he had been before. Looking in that direction—back towards the Sand Towers—he observed a distant shape he could not quite make out. Only when Stone and Bonehead leapt to their feet, hissing and stamping in agitation just before bolting, did he recognize the droon heading towards them.
As Mika continued her studies, she could not help but become aware that something major was happening in the virtual as well as the physical world. It showed itself in sudden lacks of processing space available to her, and the consequent collapses of her VR programs—which was why she was now working only through her consoles and screens. It also showed in the way any researchers who had once again donned their augs spent much of their time with their heads tilted to one side, their expressions puzzled and, more worryingly, sometimes fearful. After reaching the stage where she could stand it no longer, she used a small percentage of her system to track down D’nissan, Colver and Susan James. The latter two were not at their work stations nor in their quarters but in one of the external viewing lounges, like many others aboard the Jerusalem. D’nissan, however, was at his work station—perhaps being just as dedicated to his research as Mika.
She contacted him. ‘Something is happening.’
D’nissan’s image turned towards her on one of her screens. ‘That much is evident. Five per cent of Jerusalem’s capacity has been taken up with AI coms traffic, which incidentally started just before Jerusalem destroyed that planetoid.’
‘The destruction was perhaps the decision of some AI quorum,’ Mika commented.
D’nissan grimaced. ‘Yes, and by the timing of events one could suppose that same quorum was initiated by your assessment of the Jain structure and its “breeding” pattern.’
‘You sound doubtful.’
‘I cannot help but feel we are being gently led. It would be the ultimate in arrogance to assume that mere individual humans can make any intuitive leaps that AIs cannot.’
‘We should discuss this further,’ said Mika. ‘Colver and James are over in observation lounge fifteen. I am going now to join them there.’
‘I could do with a break, too,’ said D’nissan.
As she made her way along the corridors and via the dropshafts of the great ship, Mika reflected on what D’nissan had just said. True, AIs could out-think humans on just about every level, unless those humans were ones making the transition into AI. But to consider them better in every respect was surely to err. From where, if humans were just ineffectual organic thinking machines, did the synergy of direct-interfacing spring, the same synergy that had created runcible technology in the mind of Skaidon Iversus before it killed him? This was a question she was phrasing to put to D’nissan as she spotted him in the corridor outside the lounge.
But he spoke first. ‘You know,’ he said, ‘it’s almost as if most of the big AIs already knew what you would come up with, but were sitting on it until then—your theory, if you like, putting it into the public domain. I suspect they’ve been preparing for that.’
‘And how did you come by such a supposition?’
D’nissan turned his head to show her the new addition attached to his skull behind his ear. It was a crystal matrix aug with a buffer to visual and aural interlinks. It was the kind of item that had been around for a very long time: the CMA was a spit away from AI classification, and only the buffer prevented direct interfacing, though some synergy was achieved. Normally such devices were used by people who were gradually becoming more machine than human, for instance those who worked in the cyber industries: strange technology moles who spoke machine code more easily than human words.
‘What are you hearing?’ Mika asked, suddenly aware of how silly was her innate fear of asking direct questions, and how potentially lethal.
They entered the lounge, where floating vendors and the occasional magnetic floor-bot were serving drinks to the crowd scattered around the various tables. Most sat facing the wide curving panoramic window in which the dwarf sun now resembled a red eye glaring through bloody fog. But now the station Ruby Eye was visible off to one side, like an abandoned spinning top, so the Jerusalem must be moving away.
‘A number of AIs have suddenly dropped out of general communication, which, though not completely unusual, is worrying when some of them are the minds of warships inside the USER blockade. Also, as far as I can gather, a USER has recently been initiated within that blockade—where none is supposed to be.’
