Fun fact: Erlang started out as a modified version of Prolog. The original Erlang VM was written in Prolog as well.

What Hacker News says
2 sourcesProlog is fundamentally well established (~40 years old), and you can start using it today in several programming languages. For example:
JavaScript http://tau-prolog.org
Ruby https://github.com/preston/ruby-prolog
Rust https://github.com/mthom/scryer-prolog
Erlang https://github.com/rvirding/erlog
If your language is missing one, implementing a basic Prolog is fairly simple. Take a look at the Ruby one: it's core is not even 500 lines of code!
There are also great options like SWI Prolog if you want to build your entire app in Prolog. But I imagine it would be much easier to convince a work boss to pull in a library instead :)
Re AI: It's true that Prolog's origins involved AI, but nowadays Prolog is better suited for more general logic programming tasks (there are better tools out there for AI specifically).
