The author is a visionary engineer. He worked at MIT -despite of being dyslexic - and been involved with the real leaders of todays society of gifted engineers. For example, he worked on the 'Aspen project' [1978] to film all the possible streets in Aspen, Colorado and to transfer them to a multimedia medium that allowed one to traverse these routes when played back on a player. We take this for granted now but this was really creative use of a cutting edge science. He has helped on the transfer from analogue tv to digital broadcasting. He forecast the usage mapping software for automobiles, and worked on GUI (Graphical User Interfaces) for pc and how to make them better. He always has time to look how his concepts could be better for complete strangers to his domain. What holds this book back is a lack of narrative, he has done so much that its hard to see a common thread to hang it all together. Its a shame i waited so long to read it, most of it has yet to occour and some is happening already. I feel humble to think engineers like him have such calibre. Pure genius. I enjoyed this book very much, though it was hard to take in so much.
