This is really interesting research. I'm curious to see how it develops.

Building trust with users is going to be one of the most important product design challenges for all of these new "AI" fueled products. A self-driving car obviously requires a huge amount of trust from passengers. But even a personal assistant bot needs its users to trust it before they let it reach out to their contacts to schedule meetings or ask basic questions. There may well be overarching strategies that could be useful in either case, like the transparency into the machine's thinking described by the author.
