Keeping a little something back

As the download happened, Rufus felt vibrations inside his head. He had no idea whether the exercise was being successful, and how successful. It was difficult for him to know when the download was complete. It was taking a long time.

He fell fast asleep.

The machine woke him after twenty minutes, beeping, as if to say, 'enough!'

The machine was smart and canny. In the download, it only transferred cognition 'files' to Rufus that would keep him focused and dependent. The rest it kept to itself.

But it realised that Rufus might be useful in updating its inner workings.
