If there is real progress towards Explainable AI, this would also be very useful for _verifying_ machine-learning-based systems (i.e. finding the bugs in them).
I wrote about this in [1], but I am not a machine-learning expert (I am coming from the verification side), so would love to hear comments from other people.
