I'm not afraid of artificial intelligence: it's easy to defeat them--just pull out their plug.

I've had this problem quite a bit with voice recognition, which shows as anyone well versed in this technology will tell you: "it would make more sense to call it artificial stupidity, than intelligence." In fact, it was dealing with artificial intelligence only to be shunted to a call centre where they don't speak my language (yet again) that led to me writing this.

Yes, a computer can appear intelligent as can someone with dementia appear lucid. But as Alan Turing pointed out, a human can tell the difference. Where artificial intelligence appears superior is that it can process a lot of information quickly. But there'a another computer saying: "GIGO" or "Garbage in, Garbage out." I wouldn't trust a machine to make decisions without a human there to veto that decision. And computers need electricity or some sort of power. They can only run things as long as their batteries can power up. Otherwise they are just expensive paper weights. The reality is that they can only deal with what they are written to do. They might add some other variations to their data base, but it might confuse them since it's really just pattern recognition and not true knowledge. Or as this cartoon points out:

Of course, later versions of the Daleks could fly. The aliens in M. Night Shyamalan's Signs were able to achieve interstellar travel, yet were unable to deal with doorknobs. Or the fact that Earth is covered with water. I think Robots would have even more difficult tasks to deal with if they had to actually deal with the real world instead of their limited universes.
