You could say something similar about Cobol now. Except replace 25 years with 60 years.

Lots of people on HN would probably be shocked at how many Cobol apps are still up and running and actively maintained.

Like half of world bank systems are running on Cobol. No way its going out any time soon.

And i dont see a problem if ots working and there are people willing to maintain it if needed.

You seem to think Cobol is somehow superseded now. In fact it runs more critical infrastructure, and even sees more lines per year added for those kinds of systems, that JS does.
