Question - is prolog used in the real world? I.e. are there businesses that use prolog in production?

  Yes, there are several businesses that use Prolog in production. For example, please see the quotes from the SICStus page, a professional Prolog system (ISO standard compliant) with many commercial applications: https://www.sics.se/projects/sicstus-prolog-leading-prolog-technology https://www.sics.se/projects/sicstus-prolog-leading-prolog-t... Here is a salient quote from the article: "SICStus Prolog is a workhorse in the transport and logistics industries, running systems that handle a third of all airline tickets, and helping railways to operate their trains better." Further major commercial applications of SICStus Prolog are listed at: https://sicstus.sics.se/customers.html https://sicstus.sics.se/customers.html These include a voice-operated procedure browser for the International Space Station, and a dispensation order generation algorithm for biological research. In addition, Prolog is often used in logistics software and for scheduling, among several other tasks for which it is very well suited. A commercial Prolog's multi-user license easily costs thousands of dollars, so an industrial strength Prolog system is not the kind of software you typically "just buy" as an individual. Typical customers of commercial Prolog systems are other companies, and also universities who buy licenses for research purposes and to teach Prolog.
