OK, maybe now it's time to start worrying. While artificial intelligence has been making considerable progress, the doomsday scenarios painted by science fiction are still years, if not decades, away in the absence of one critical factor: self-awareness. Now that might actually start to be a concern. Rensselaer Polytechnic Institute professor Selmer Bringsjord demonstrated how those cute and polite NAO robots have been able to gain an extremely short instance of self-awareness. OK, maybe we don't need to panic just yet, but it's a start.
