This is an interesting article about how to be "depressed" about the technologies to come: Technology's Frontier Syndrome. If you are not a big connoisseur on the art of computing, you won't probably relate to the article, so I suggest you just to skip it. In a nutshell the author claims that we will never have a solution to all our computer problems. New solutions will only work while they are new solutions. Hackers, viruses, spam, will always find their way to work on this new "environment" eventually. Why should be bother, then?
