I found this site:http://www.ftrain.com/google_takes_all.html written 2002 talking about Google in the year 2009. It is interesting and entertaining reading and a lot of things, especially the "SEMWEB" seems to be here already...
That was entertaining, but I doubt it'll ever happen. People are much smarter these days. I don't think there'll be a second crash. In any case, it won't be as huge as the original bubble burst.
