How Artificial Intelligence still has a big part to play.
There's no stranger field than Artificial Intelligence. The science of making intelligent machines has never had greater potential—or seemed more insurmountably difficult.
The more we study the human foundations of intelligence, the deeper we probe into the massively parallel processor that is the human brain, the less plausible seem our first attempts at creating artificial thought close to our own—and the more likely that we won't perceive it as real, that is human-like, intelligence.
For every human-capable task, there is a different criterion for intelligence—some tasks like number crunching convince us computers are superhuman, some like language processing that they're sub-human—but rarely is a computer consistently on our level.
