From tech reporter Brian Bergstein at Technology Review:
Is it possible to give machines the power to think, as John McCarthy, Marvin Minsky, and other originators of AI intended 60 years ago? Doing that, Levesque explains, would require imbuing computers with common sense and the ability to flexibly make use of background knowledge about the world. Maybe it’s possible. But there’s no clear path to making it happen. That kind of work is separate enough from the machine-learning breakthroughs of recent years to go by a different name: GOFAI, short for “good old-fashioned artificial intelligence.”
If you’re worried about omniscient computers, you should read Levesque on the subject of GOFAI. Computer scientists have still not answered fundamental questions that occupied McCarthy and Minsky. How might a computer detect, encode, and process not just raw facts but abstract ideas and beliefs, which are necessary for intuiting truths that are not explicitly expressed?More.
