The Blue Nowhere

I was amazed when I read the end of this novel that most of the technology exists that was portrayed in the book. I don't search the web very often and barely knew hackers existed except what I read in the newspaper. I am dismayed that what is potentially such a good thing (the internet) can be used for so much bad. I don't mean to take a cynical view but I think that the very real threat of hacking scares me.
