PROLOG - such a great idea, never really caught on. Yeah yeah I know minikanren and clojure core.logic but realize its gone from "The Japanese are using it to leap ahead of American AI research so we gotta catch up" in the late 80s to "whats that?" today.

To eliminate some battles over the definition of the word dead, how about "without too much effort you can get a paying job writing it". That works pretty well for spoken languages too.

That helps with Assembly. As a fraction of the pie its never been lower. As a device driver, embedded, firmware, compiler optimization (does that count?), and boot loader type of technology there's probably never in human history been more lines written per year. So its both dead and thriving by some definitions, but by my definition above its hardly dead.
