From a Prolog perspective I think they're bad results.<p>It's more popular than languages like OCaml, COBOL or Nim. This is not too bad I guess, I somehow got the impression that there were more people from all those languages than in Prolog.<p>However it is the second least desired language (after Zephyr), and the second least admired language (after MATLAB). That means people don't want to learn Prolog, and people working with it don't want to continue doing it.<p>But, is it well paid? No, Ada and Prolog are the least paid languages (but compared to 2023 there's a big change here, so there may be some noise here).
