I dunno if it's just me or where they not clear as to what they meant by complex systems. Where they talking about just complicated things or more like: <a href="http://en.wikipedia.org/wiki/Complex_systems" rel="nofollow">http://en.wikipedia.org/wiki/Complex_systems</a>. I know it's not a really important point of the article but I can see how this type of stuff would make no sense to everyone but people who have knowledge of what complex systems are. Basically I can see how the management of these companies didn't want to interfere with what they didn't understand but seemed to work. But now it's easy to say that stuff was all crap and cause us billions. I hope that some of the science these guys were working on can be salvaged (the good parts at least).
