Why would you want to convert COBOL into other languages? There is a reason why it still used.
Anthropic put out a paper. Not an actual product.
and, the main point is, who is going to maintain the spaghetti that is going to come out of the "conversion" ?
Right. I just found it funny how IBM stock went down at the slightest hint of the possibility. They probably charge an arm and a leg for those maintenance contracts.
As for COBOL, I heard it's a nice language.
