SQL. I had already done some Prolog in CS class, and I thought that I knew what it was all about. Writing thousands of queries as a data analyst made me really think about how to reason logically and constructively.

People talk about logic programming as if it has fallen from grace and will never be able to deliver on its promise, but I'm convinced it is yet to make its biggest impact.
