Yes to your point, COBOL which ranks very low here is still fundamental to the infrastructure of several major industries, with some sources [1] reporting that it is used in:
43% of all banking systems.
95% of all US ATM transactions.
80% of all in-person credit card transactions.
96% of travel bookings.
This may very well dramatically change in the next few years with such an emphasis on enterprise AI tools to rewrite large COBOL repositories. [2]
