The rise of the Projects, according to Dr. Kilbillie, was the result of many many factors, but two of the most important were the population explosion and the Treaty of Oslo. The population explosion, of course, meant that there was continuously more and more people but never any more space. So that housing, in the historically short time of one century, made a complete transformation from horizontal expansion to vertical. Before 1900, the vast majority of human beings lived in tiny huts of from one to five stories. By 2000, everybody lived in Projects. From the very beginning, small attempts were made to make these Projects more than dwelling places. By mid-century, Projects (also called apartments and co-ops) already included restaurants, shopping centers, baby-sitting services, dry cleaners and a host of other adjuncts. By the end of the century, the Projects were completely self-sufficient, with food grown hydroponically in the sub-basements, separate floors set aside for schools and churches and factories, robot ore-sleds capable of seeking out raw materials unavailable within the Projects themselves and so on. And all because of, among other things, the population explosion.
And the Treaty of Oslo.
It seems there was a power-struggle between two sets of then-existing nations (they were something like Projects, only horizontal instead of vertical) and both sets were equipped with atomic weapons. The Treaty of Oslo began by stating that atomic war was unthinkable, and added that just in case anyone happened to think of it only tactical atomic weapons could be used. No strategic atomic weapons. (A tactical weapon is something you use on the soldiers, and a strategic weapons is something you use on the folks at home.) Oddly enough, when somebody did think of the war, both sides adhered to the Treaty of Oslo, which meant that no Projects were bombed.
Of course, they made up for this as best they could by using tactical atomic weapons all over the place. After the war almost the whole world was quite dangerously radioactive. Except for the Projects. Or at least those of them which had in time installed the force screens which had been invented on the very eve of battle, and which deflected radioactive particles.
However, what with all of the other treaties which were broken during the Ungentlemanly Gentleman's War, by the time it was finished nobody was quite sure any more who was on whose side. That project over there on the horizon might be an ally. And then again it might not. Since they weren't sure either, it was risky to expose yourself in order to ask.
And so life went on, with little to remind us of the dangers lurking Outside. The basic policy of Eternal Vigilance and Instant Preparedness was left to the Army. The rest of us simply lived our lives and let it go at that.
But now there was a spy in the elevator.
When I thought of how deeply he had penetrated our defenses, and of how many others there might be, still penetrating, I shuddered. The walls were our safeguards only so long as all potential enemies were on the other side of them.
I sat shaken, digesting this news, until suddenly I remembered Linda.
