I agree with Legacy code solutions. It depends on a lot of things.
As for the latest Cobol issues so true! Probably the youngest programmer is like 60 or something.
PHP is actually not your 5.x php anymore. It's much closer to Java these days and the php frameworks are enterprise too. I noticed that lots of frameworks pick up from Java. Lots of what you mentioned about newer code really depends. I wouldn't discount a lot of languages because X hipster language is nailing it today. I have seen lots of cool languages wither away. Developers are like artists - horribly self indulgent and finicky.
Go, Rust, Zig are your hype back end languages these days.
React is winning on the front end ... but the landscape is continually evolving.
Node is innovative but lots of tinkering developers exist in that space and projects die off like cut flowers.
I think Cobol is a major lanague in the logistics world. Yes, the devs are like 60 + and most don't want to fix Windows XP style of hodge podge patch upon fix upon workaround anymore.
Just wondering, what do you consider as a new language?
I am also tryig to figure out what can be done with Ai ... that can't be done in an older language like PHP.
