Meh.
It starts out strong, in that I really liked reading Virilio discuss his architectural theories in detail. The "oblique function" stuff was neat, and interesting, and showed a crafty mind.
But it was in the second half, when he started getting into his theories around what he calls dromology (the "science (or logic) of speed") that I felt things lost the plot a bit. Not even about dromology itself, more that he used it as a jumping off point to critique modern technology - with frequent references to eugenics, Nazism, Aushewitz, etc - and how humanity itself is threatened by the pending advent of the super-human to the point that he started to sound more and more like a crank than an important thinker.
But this is a slight little book, and is made up of transcripts of discussions that occurred over a three year period. So it's tough to get a real gauge on what he's really saying, as much of the conversation seems to be an overview of nearly thirty years of his work, so I can't tell if his thoughts are simply incomplete - or incomprehensible - or if the format simply allows for too many gaps and assumptions. All in all, most of what he says comes off as simply unsupported conjecture, but it's difficult to provide the detail needed to support the weight of his pronouncements in under 200 pages...
It's unfortunate, because from what I can tell, I'd likely enjoy his works centered around the "War Model", but it's not really dealt with here. I might give some of it a shot if I stumble across it.
