Read some hacker/cracker zines from the late 80's/early 90's (Phrack, 2600, etc being the well known ones) and you'll quickly gain a deep perspective on the pace of computing/IT security advancement over the decades. Stuxnet and Duqu will suddenly appear to be a minor revisions of 20 year old technology/techniques. You'll see code for polymorphic engines written in TurboPascal suddenly break out into obscured x86 assembler interrupt handlers. Detailed analysis of reverse engineering efforts against "packed" code on foreign and obscure architectures. And the word "cyber" used in all seriousness.

It is quite amusing to see how many old ideas from the dawn of computing have been reinvented multiple times over the years.
