This is the million-dollar question out there in terms of the broader impact on the economy.
What I know from looking at the most recent emerging literature in this space—there are quite a few economists doing work on this—is that we've only started to see a little bit of an impact on labour markets, at least in the North American context. There's a little evidence right now that entry-level workers are potentially the ones being most impacted. This was from a study that came out of Stanford last year looking at the U.S. economy.
To look at your broader question, look at previous historical trends of technology. What always gets underestimated is what gets created by a new technology. I'm more of an optimist at heart when it comes to the capacity of humans to invent new demands and new ideas from technology. In the long run, I think we will find ways to employ everyone and to make sure that this technology is being utilized, but we need to be very careful about that transition and particularly people who might be disrupted by it happening too fast.
