No offense intended, but "As UAs become more sophisticated, they can
analyze——" generally indicates a problem.
I believe that the above can work for min and max. However, expecting
user-friendly natural language descriptions of regular expressions
(in multiple natural languages!) to emerge "as UAs become more
sophisticated" is in the realm of expecting future AI-complete magic
software to fix things. In general, that's not a good assumption to
make.
