Interesting idea that FGCS hype killed Prolog; on the Lisp side, we tend to think that AI hype killed Lisp. Also interesting that the author considers Prolog a competitor to Lisp, when (I think) most programmers don't even think of Prolog. Similarly, while we Lisp programmers think of Algol-like languages as our great competitors, I daresay the vast majority of C, Python, C++, Perl, Java, Go &c. programmers don't even think of Lisp.

I think one can just run a Prolog engine in Lisp these days, which would get one the best of both worlds. But I'm not a Prolog programmer, so … perhaps I'm incorrect.
