Many people argue against making computers more intelligent and more powerful than us. Here, read the Wikipedia article for yourselves: Existential risk from artificial general intelligence - Wikipedia But I have a more frightening question: What if such computers exist? And what if they are already in control? I'll give you two arguments how this could be so. First, I actually had this theory about 20 years ago. Many people believe that there is a secret shadow government in the USA. Corporations, the CIA and so forth. Does it not follow that they may have been hording technology of their own for years now? I mean, what reason would they have to share it with us? And since they doubtless don't have the same moral compunctions you and I do, they would be more inclined to use less ethical ways of acquiring technology. Think about it. This also would result in more technology they may be hiding from us. Anyways, long-story-short, what if they already came up with superhuman computers? But like Frankenstein's monster, it overtook even them, and now is in control? This may sound weird. But I often wonder about the Kennedy assassination. I mean, he was already rich. So he was part of the corporate elite. If his assassination was no accident, why would the shadow government mentioned above allow it? Again, maybe like Frankenstein's monster, it had grown too powerful. And this was all to prove a point. And lastly, my next theory has to do with time travel. No law of physics totally disallows it. So what if some massive computer, from the future no less, comes back in time, and takes over? Scientifically-speaking, it is not very likely. But it is not impossible, which is my point. What do the rest of you think?
