And COBOL is listed as third-generation on Wikipedia, too.
I now remember reading about this concept of generations in a book about Ada, it seemed fascinating then but turned out to not be as good as expected 🥲
Also, Unix Shell is listed as 4GL example. There are SPSS, MATLAB, R, and Wolphram Alpha in the same list of examples, that kind of shows where 4GL went today.
No, only the farm that convinces people to listen to other farm(s). And those already exist, anyway :(
