Soon, very soon, the central processing engine of the construct’s brain was whirring and clicking at full capacity. Ingenious mechanisms kicked in at the behest of the new programmes buzzing through the analogue valves. Sections of analytical capacity normally given over to movement and backup and support functions were folded in on themselves, doubling their capacity as the same binary function was invested with double meanings. The flood of alien data was diverted, but not slowed. Astounding articles of programme design increased the efficiency and processing power of the very valves and switches that were conducting them.

David and Isaac talked upstairs and grimaced or grinned at the sounds the hapless construct could not help but make.

The flow of data continued, transferred first from the repairman’s voluminous set of programme cards and stored in the gently humming, clicking memory box, now converted into instructions in an active processor. On and on came the flow, a relentless wash of abstract instructions, nothing more than combinations of yes/no or on/off, but in such quantity, such complexity, that they approximated concepts.

And eventually, at a certain point, the quantity became quality. Something changed in the construct’s brain.

One moment it was a calculating machine, attempting dispassionately to keep up with the gouts of data. And then awash in those gouts, something metal twitched and a patter of valves sounded that had not been instructed by those numbers. A loop of data was self-generated by the analytical engine. The processor reflected on its creation in a hiss of high-pressure steam.

One moment it was a calculating machine.

The next, it thought.

With a strange, calculating alien consciousness, the construct reflected on its own reflection.

It felt no surprise. No joy. No anger, no existential horror.

Only curiosity.

Bundles of data that had waited, circulating unexamined in the box of valves, became suddenly relevant, interacting with this extraordinary new mode of calculation, this autotelic processing. What had been incomprehensible to a cleaning construct made sudden sense. The data was advice. Promises. The data was a welcome. The data was a warning.

The construct was still for a long time, emitting little murmurs of steam.

Isaac leaned far over the railing, until it creaked unnervingly. He pushed over until his head was upside-down and he could see the construct beneath his and David’s feet. Isaac watched its uncertain juddering starts and frowned.

As he opened his mouth to say something, the construct pushed itself up into an active posture. It extended its suction tube and began, tentatively at first, to clear the floor of dust. As Isaac watched, the construct extended a rotating brush behind it and began to scrub the boards. Isaac watched it for any signs of faltering, but its pace increased with almost palpable confidence. Isaac’s face lightened as he watched the construct perform its first successful cleaning job for weeks.
