I think this is a really nice idea, and it seems somewhat more memorizable than a what3words address because it incorporates numbers. Really cool work! The only two complaints I have are 1) as others in this submission have said, is that the list should really be curated, or at least be filtered to remove "bad words", and 2) ideally this algorithm could be tweaked to not require a city to go along with it, so it becomes easier for a place that hasn't been able to designate cities can use it more easily.
