"Right in one. The guys who'd come up with it in the first place had put a lot of work into it during the fifty years before the crash. Other corps too. They’d got it a lot smoother, so you didn’t need the two supercomputers and the drekload of other stuff. The way I hear it, they got it down so one tech could run it, and all the hardware would fit in one big van. Then poof! The virus blows it all away. Maybe the guys who’d actually done the research were killed in the rioting, or maybe the corps had already ‘vanished’ them. Whichever, they weren't around to tell anybody what they'd done.
