"I don't like it any better than you do," said Chang. He
turned to Armstrong. "We tackled some geophysics. We've
never had a full computer solution for the rotational mo-
tion of the Earth -- too messy, with core convection, tidal
forces from the other bodies of the Solar System, and the
inhomofeneous heat balance calculations. So a few months
ago I decided to let Dominus have a go at it. We switched
the full system on only for short test spells, a few minutes
at a time, but with its speed that's an incredible volume
of computation. We produced a nice result, with detailed
predictions of polar motion for the next year. Everybody
was very happy, and we were even more pleased when we
checked the predictions against the new observations, and
they were spot on. we sent the results along to the Naval
Observatory, and were all set to write up the results."
He paused.
"Until?"
"You've got it. Until the Naval Observatory people called
back here, to point out that there had been errors in the
previous observed values they had sent us for polar wan-
der. Those erroneous values had gone into the inputs that
Dominus used in its calculations. The correct historical
values would have led to different predictions. Dominus
has been making the wrong predictions -- and the Earth
has been following them."
"Rafael, that's impossible."
"I know it. It's also what happened. These last few
weeks I've been thinking. If you build a machine that
performs as many logical operations in one second as the
whole human race performs in a year, what will its state
be at the end of a few hours of operation? What capabili-
ties might it have that we can only begin to guess at?"
Before Armstrong could respond there was a sudden
increase in the noises of the crowd outside. He looked at
his watch.
"I see. Three minutes past six. Jesus, just look at them."
The crows below was so densely packed that the snow
cover was hidden. Beyond the main group, smaller clus-
ters were dotted over the frozen surface, out past the
point where the yellow floodlight ended. There was no
movement except for a steady rocking back and forward
of each person. The sound level was growing, a sibilant
continuous hissing over lower muttered consonants. It
was a single word, repeated over by forty thou-
sand voices.
DOMINUS... DOMINUS...DOMINUS...
Rafael Chang leaned forward, staring down to the area
closest to the building. "I hope the guards down there
don't over-react. The demonstration is timed to a seven
o'clock peak, when Dominus was scheduled to be fully
integrated."
"The crowd doesn't look violent. They seem to be in a
trance, almost," said Bevin. "What are you going to do,
General?"
After one long look at the crowd below, Armstrong had
leaned far back in his chair and closed his eyes. He seemed
oblivious to the other two, and to the sounds and sights
outside the building.
"Tell me, Jim," he said at last. "you've been testing the
subunits of Dominus for over eight years. Correct?"
"We started in May of '91, didn't we, Rafael? So it's
been eight years and eight months."
"And for all that time, you've been building and testing
pieces of the final system. Now tell me, is there any part
of Dominus, even the smallest circuit, that hasn't already
been used, many times over?"
"Not a chip. We've never had all the system integrated,
but we've done module testing a hundred times."
"That's what I thought. I've another question for you.
Rafael, what data bases do you keep online at this
installation?"
"The complete list? I can't quote you that off the top of
my head, but we can read it out through a terminal easily
enough. I know for a fact that we've got complete physics
and math for all the major journals, and there's chemical
abstracts, and all the important electronics references,
plus a lot of geology and astronomy. Plus a smattering of
other stuff. Do you want everything?"
"No. That will do. Jim, can you perform final system
integration from here?"
"Right at that console," Bevin pointed a finger over his
shoulder. "If we decide to go ahead, it would be a two-
second job."
"Good." Armstrong stood up. "I've made my decision.
Go ahead, bring the system online. Do it now and let's
disperse those demonstrators before they all freeze. But
we have to do one other thing as well. I want you to call
Washington on a Domsat link and start transferring other
data files into your banks here. Bring Dominus up, then
I'll give you the access codes."
