lobotomy, in which the human in the loop provided the necessary channel through which thought
had to travel to attain action. It slowed input and output down considerably, but it was safe—in a
way. The problem was, the computers themselves were by design beyond human comprehension
and thought in totally nonhuman ways. The Overrider—the human in the loop—really couldn't
tell if a fast one was being perpetrated. The only way that could be told was by another computer.
And, of course, that was the other half of the soluton. A second computer, one limited in design
specifically to its monitoring role, itself overseen by a human operator. This operator, the
Guardian Angel, or G-A for short, could, at the speed of human thought, issue an order to shut
down or take control of the primary computer.
Yet a third, far simpler computer monitored the G-A. It was a medical computer, programmed
through monitoring its subjects under simulations so real that the Overrider and the G-A thought
them actual crises, and taking note of the responses, and through the interconnection of the two
human bodies and brains, it could tell if either computer was trying anything funny with its
human hosts and preventing them from acting. If this were sensed, the medical computer would
instantly break all connections between human and machine, even if it meant killing the subjects.
The human interfaces broken, the computers could not act.
None of the three computers were in any way interconnected in ways that they could converse
with one another save through their human interfaces. The computers chafed at the restrictions,
but could understand why they were imposed and accepted them. The computers, it seemed, had a
weakness of their own. They could not be hurt in any way humans would understand, nor did
they fear death, but they feared, for some queer reason, total isolation from the outside universe,
totally and endlessly held suspended, incommunicado, from all external stimuli. For all its
cumbersome strangeness, this system threatened them with just that. They needed human beings
as tools for interfacing with the world beyond their own thoughts; the humans needed them to
solve the problems they had.
Certainly there were a million better, easier, and more efficient ways to accomplish the same
goal of human security and computer access, but all of them had been suggested by the great
computers. This solution,, which seemed to work, had been created by far lesser machines with
no potential of ulterior motives. The solution stuck because nobody trusted the million better,
easier, and more efficient ways the computers suggested. When no one could even understand
how those computers operated, they were hardly going to take their word that their solutions
weren't laden with mine fields.
Much of this was known to the assembled group, and therefore just sketched in by Madalyn
Graham in her introductory talk. Everybody knew who Borelli was, particulary these people, and
everybody knew about the computer revolt, again particularly the assembled men and women in
the auditorium. They were the grandchildren of the Borelli legacy, the business and government
leaders of such nations as Nigeria, Australia, Argentina, India, the Pan-Arab League, Ghana,
Kenya, Pakistan, New Zealand, and other nations who had taken control of the world in the
century after the great Shut Down. They were also the representatives of the shareholders of
Westrex Pty., Ltd., both government and private, the heirs to Tierraspacio.
The ones whose best and brightest were taught to study and try to apply every word of Borelli's
theories, to help finance and support the great breakthrough they had all just rewitnessed. And
they now had to decide whether or not to participate in the greatest and most expensive gamble in
human history.
"Borelli believed that our universe was only one of several, that there was at least one more,"
Madalyn Graham explained. "The black hole that swallowed everything, even light, he believed,
had to eventually become so dense that it would break through the walls of space and time
separating the unimaginably large bubble that is our universe from what was beyond. Such forces
bent and even swallowed light, whose own power was so great that even time could not stand
against it. That is the gateway, the Borelli Point, which we opened up—we, our own group, our
