I remember being told as a kid that that the most impressive computer on the planet rested inside my noggin. Sure, computers could be programmed to do math faster than I could (no real achievement there), recall facts more accurately, or any other number of trained tricks, but it couldn’t think.
That notion seems to be moving by the wayside. No, we don’t have any true artificial intelligence yet, but computers are becoming ever more sophisticated in the way they work and process information. The programs responsible for this behavior have become more complex, taking into account more variables, but no one can program for every possibility. That sort of learning only comes from experience.
