OR new languages and frameworks ever again, since they'll slow down code generation due to lack of training, and from LLM generation standpoint this is a terrible thing to trade off.
I’d rather wait 5-10 years for a stdlib way of handling JSON, XML, YAML, TOML and other formats than using unproven libraries made with unserious practices that have edge cases. The same applies for processing requests, doing any sort of multiprocessing, DB interaction, validations, hell even any and all front end work all they way down to CSS. Don’t even get me started on desktop and server software and OS stuff.
Maybe then software engineering can be treated like real engineering.
