Ankit,
You’re in the wrong forum, we have a forum dedicated to such questions.
For the record Deep Blue did not use any AI techniques, but pure raw computing power. It was simply able to test a vast number of combinations of moves ahead and very simply select the move that gave the start of a good sequence. It was actually very crude. What were remarkable were the reactions and comments made by Kasparov. He had played against many computers and claimed he was able to easily recognize their very mechanistic approaches. He became very angry when playing against big blue because the machine appeared to be adopting strategic styles he had only ever encountered while playing against people, he strongly suspected that there were people helping big blue.
He was beaten not by AI or people just a faster than usual computer.
This fact sets the scene for true AI which need to model far more complex events than a simple game of chess, and for that there needs to be a greater increase in computing power.
It is estimated that to emulate the human brain we would need the equivalent of 100,000,000 x 1GHz Intel processors all functioning together. If Moore’s law continues to hold (computing power doubling each year) then we should have the computing power to emulate the human brain in about 20 years. During that time AI will continue to be developed and will become increasingly effective as more computing power becomes available.
But what is the goal? There isn’t one really apart from knowing that smarter machines tend to be more helpful than ones that are dumb. But if AI software becomes efficient then it should achieve the equivalence of the human brain at some point and then continue past that, at which point AI machines will become the dominant intelligence on the planet. What does that mean for us? If the AIs are benign then we should survive, if not then that is probably the end of the human race. Others say that we must adapt ourselves so that we can compete with the AIs, and that means various forms of augmentation or even as far as having our own brains scanned and uploaded into the processing units that are also used to house the AI software.
Hope that gives you some idea of what could or might happen. Whether it will happen as I describe no one really knows at this point.
