That is a solid point, at the end of the day, programming languages and frameworks are just tools we use to build a product that has some use to someone (Be that monetary value or art or whatever). At work, it is almost always better to just iterate on the existing tool stack rather than try to spool up new one. I love writing Rust, but I'd need a good reason (or at least a big project to amortize the cost over) to reach for it over the existing very function c++ libraries I already use for our embedded work.
