Is AI being oversold?

It was oversold in the past. Easy to see why – the potential gains were (and still are) enormous and any indication you were on the right track meant people would throw money at you. And if you then couldn't deliver anything monetizable, the money people would shred you and your reputation. DL systems have achieved near-human performance in at least 6 problem domains (signal processing, low-level speech understanding, image understanding, text understanding, Atari games, and Go). From now on, we can use incremental improvements and we can reliably measure our progress.
