US Treasury Secretary claims that AI's impact on jobs is 50-100 years away

In context, it is clear that he is referring specifically to the idea of massive structural unemployment rather than the long-standing situation where new technology displaces jobs but people find new ones. I think this can be regarded as pretty mainstream. His AI referent is specifically clarified as not being self-driving cars (he expects) but r2d2 robots that can replace human interviewers (he doesn't expect soon).

I have a computer playing DOOM on a shelf in this room, right now actually. I've poked and peeked around the code and I'm really starting to get a good understanding of the structures and methods used by the software. I've started designing better AI bots to play Doom, some of them fail to learn better than others, and others I make do learn better, and faster. Later I plan on implementing an AI inside a hex-bug creepy crawling robot toy.

Did I mention, I'm a high school drop out, if that doesn't strike fear into you, I don't know what will. In this "the golden age of information" there is no excuse to not learn something. 50-100 years? I don't imagine it taking more than a few years, but only if the money was in the right spot, so maybe, yeah, 50 years.
