"I still haven't said I'm going to do it. I'd like to help you, Amos. I'll take your word about the plan. It has possibilities. But that still has nothing to do with my own problems. Right now Diane is the most important thing." "Diane's future, your future, all our futures ultimately depend on this. What's the matter with you? You fail to see the forest for the trees. Tomorrow, what's tomorrow, with all mankind's days ahead of us--slave or free? Perhaps one man could do the job alone, although two would have a better chance. But I think you know I'm not the man for the job. I don't await your answer, Johnny Hope. I've no one else to turn to. Humanity awaits your answer." "Let me think," said Johnny, waving Westler away when he would have continued talking. More quickly than he dared hope, he had found Diane. With equal swiftness, Westler had discovered what he sought. That left Johnny in the middle of a tug-of-war which wouldn't wait indefinitely for his answer. * * * * * As the closing gong sounded, 63-17-B watched the Shining Ones shuffle away from their benches and make their way down the corridor toward the cafeteria which would serve them an unimaginative but well-balanced evening meal. But two humans remained behind, talking avidly over the gleaming bodies of two stripped-down Robots. Strange, thought 63-17-B, who was now confronted with the first even mildly unusual event since taking over the dull routine of his new job that they should continue working after the closing gong had sounded. He could summon Hartness, the scarred human supervisor, and have him talk with the two, or ... Hartness, his metal-jointed foot! He would do no such thing. If perhaps the humans were up to some mischief, and if it did not endanger 63-17-B's own position still further, then let them play. If it gave a few Robots and even Central Intelligence a hard time for a while, it served them right. Of course, nothing really serious could come from the tampering of two helpless humans.... "What about that guy up there?" Johnny raised an eyebrow in the direction of the supervising Robot, motionless on his stone perch. "Is he watching us?" "It appears that he is. Unfortunately, we can't do a thing about it. At least not until we find out if these gadgets will work with us inside them. Here, Johnny--you see these tiny items? These are transistors, using germanium instead of a vacuum grid to activate electrons, smaller, more compact, more powerful, of longer life. Without them the whole science of cybernetics which ultimately made the Robots possible would never have advanced beyond the rudimentary stage. For with transistors replacing vacuum tubes you still need the entire U.N. building to house Central Intelligence. Under the older system, all New York City would not have been enough."
