At first, because of the excessive radiation, none of the Earthmen could remain outside the ship for long, even in radiation suits. And one morning, when Steffens came out of the ship, it was to discover that hundreds of the robots, working through the night, had effectively decontaminated the entire area.
It was at this point that Steffens asked how many robots there were. He learned to his amazement that there were more than nine million. The great mass of them had politely remained a great distance from the ship, spread out over the planet, since they were highly radioactive.
Steffens, meanwhile, courteously allowed Elb to probe into his mind. The robot extracted all the knowledge of matter that Steffens held, pondered over the knowledge and tried to digest it, and passed it on to the other robots. Steffens, in turn, had a difficult time picturing the mind of a thing that had never known life.
He had a vague idea of the robot's history—more, perhaps, then they knew themselves—but he refrained from forming an opinion until Aliencon made its report. What fascinated him was Elb's amazing philosophy, the only outlook, really, that the robot could have had.
"What do you do?" Steffens asked.
Elb replied quickly, with characteristic simplicity: "We can do very little. A certain amount of physical knowledge was imparted to us at birth by the Makers. We spend the main part of our time expanding that knowledge wherever possible. We have made some progress in the natural sciences, and some in mathematics. Our purpose in being, you see, is to serve the Makers. Any ability we can acquire will make us that much more fit to serve when the Makers return."
"When they return?" It had not occurred to Steffens until now that the robots expected the Makers to do so.
Elb regarded him out of the band of the circling eye. "I see you had surmised that the Makers were not coming back."
If the robot could have laughed, Steffens thought it would have, then. But it just stood there, motionless, its tone politely emphatic.
