After a pause, when there came no reply, he gazed in a direction few other humans could perceive, and stepped there. Mars faded around him, and momentarily he existed in a realm without colour, distance, or even time. Then he was pacing towards a runcible gateway on that same world, curious faces turned towards him. He ignored them, stepped through. Another transit lounge, gravity even lighter and his steps bouncing. He located himself, then transported himself again into a very secure chamber in the Tranquillity Museum on Earth’s moon.

At the centre of this chamber rested a hemispherical chainglass case covering innocuous looking coralline objects. The column this case rested on he knew contained a CTD—Contra Terrene Device—the euphemistic term for an antimatter weapon. The chamber he stood in also sat on top of a fusion drive. In an instant Earth Central could cause this chamber to be ejected intact from the museum and, when it was a safe distance from the moon, detonate the weapon it contained. Blegg turned, eyeing the display screens ringing the walls. They all showed recorded microscopic and nanoscopic views of the objects within the case—only a few of the millions of images available, though subscreens could be called up to gain access to a huge body of data concerning the complex molecular machinery revealed. However, this chamber was closed to the public now—had been closed for some years.

‘So, Hal, what are the prospects for the human race?’ Blegg asked.

One of the screens changed to show a simple graph. The bottom scale was marked off in dates from 1,000 ad to the present, while the side scale gradated in the currently accepted units of technological development. For five hundred years the graph line rose only a little above zero, began to curve, then shot sharply upwards with the onset of the Industrial Revolution. By the twenty-first century the line speared up and had disappeared off the top of the graph by the twenty-third century.

‘That’s wrong,’ said Blegg.

‘Two things,’ said the Earth Central AI. ‘The first is that calling me Hal is now a positively geriatric joke, and the second is that yes, the graph is wrong. This was in fact how the twenty-first-century humans saw the prospective development of the human race. Those same humans expected their descendants of this time to be something akin to gods and perhaps utterly unrecognizable to them. But this happened instead.’

The line changed now, beginning to curve back down towards the end of the twenty-second century, and in the next century returning to a rate of growth akin to that of over a thousand years earlier.

‘Life just got too cosy,’ suggested Blegg.
