Define true intelligent machines?
How can a machine "think"? Do they think as we do? Is the word "think" correct to use?
No matter how much you improve it, and you program it, to react just like humans and to find maths theorems and discover some scientific facts, and be just like a human, it's still a machine, and it don't "think", it analyze and reacts, it's programmed, it can do art, but not as we do, it's based on a DATA base, and resulsts from analyzing that DATA base and etc... meaning coming up with new things for example, wich is still analyzing and concluding, something like that, it can't work like the human brain work, it don't have dreams for example, inless you make it to have some kind of dreams, but that means nothing to it anyway, you can make it (the human-like robot for example) have emotions and reacts to different situations with human emotions that it even look like a real human and you don't even notice that it's a robot, it's still a machine, programmed to represent those emotions according to situation, even if it learns, it still means nothing to it, cause it's just some made for us humans to see, and not for robots to actually feel it and etc..
I don't know if "True intelligent machines" expression is correct, you may say intelligent machines, super intelligent machines, etc...
Maybe I'm wrong and you can call it true intelligence, I mean, if it learns (gather informations) and analyze it, and get new datas (new things; discover) and etc... I mean, our brain works like that after all, but it sure not in the same way ours do, also it can't have real emotions (inless by real emotions you mean emotions that you see from outside).
