Surely you've seen this little gem before?
I'll quote the relevant passage:
(Picard) "But the Borg have the ability to adapt. Won't they alter their processing systems to increase their storage capacity?"
(Data) "Yes, Captain. But when `Windows' detects this, it will create a new version of itself called an `upgrade.' The use of resources increases exponentially with each iteration. The Borg will not be able to adapt quickly enough. Eventually all of their processing ability will be taken over and none will be available for their normal operational functions." |
