While the future impact of artificial intelligence might seem like a subject more suited to movies, it is becoming an ever more mainstream discussion.

In the article, he mentions Google's driverless car, a weak but useful form of AI that continues to improve rapidly - Google put in a patent request last week on detection of aggressive drivers.
