Ask HN: Is Algol used anywhere today?

I can't answer your question, but I immediately thought of Perlis's preface to SICP: "Algol 60, never to be an active language again, lives on in the genes of Scheme and Pascal."

Did racket revive Algol 60, even if with a weak pulse?

According to the ALGOL 68 page at Wikipedia: "Steve Bourne, who was on the Algol 68 revision committee, took some of its ideas to his Bourne shell (and thereby, to descendant shells such as Bash) and to C (and thereby to descendants such as C++)."
