Right now we have what is called "linear" computers that do millions of calculations one after the other and with each calculation another variable is entered that produces its own numerous number of calculations. Up to now scientists have been working to make computers faster and faster to handle more and more calculations. Yes they are reaching the limits of that style of computer technology.
BUT the new field of quantum computers blows all that away and they are making real progress in this field. This new generation of computers will make "Deep Blue" look like an abacus by comparison. Whats the new parameter? It's simple, a quantum computer can do ALL calculations at once, in an instant. Yes the computers capable of out thinking and out doing a human mind on so many levels are on their way and is why people like Stephen Hawking have been raising their voice against this new artificial intelligence.
As an example, even the simplest quantum computer could break all secure security codes in all locations basically within seconds. Nothing would be safe from such technology, nothing could be kept safe. Whatever passwords are used, whatever login names, none of it would slow down the new computers. Everything would be open to access because of this ability to do all calculations at once.
And this is just the beginning. As i have read a number of times recently, we are at the cusp of a technological revolution about to happen world wide. None of us are ready and none of us really has any idea of the ramifications. Not even the smartest scientists of the likes of Hawking.
