Read: Skynet Becomes Self-Aware: How to Welcome Our AI Overlords from Wired.com
Of course what the author fails to identify is that we all know that Skynet is fictional... Google however, I strongly believe, is not far away from being self-aware if it isn't already? In fact, does anyone actually know who's running the show... Hmm, quick search on Google says actually quite a lot of people know. But then again, who told me this - Google did! Well it would pretend real people are running the shop and not some self-aware planet wide intelligence plotting our doom.
Could the internet ever truely become self aware? There are those who think yes!
