Well put- this resonates with my way of thinking too. I do think there’s some work you need to put in first to be able to easily pick up a new language. If you’ve learned a few, you can focus on what’s different about it- but there are some concepts in many languages that take some getting used to. If you’ve never done purely functional programming before, if everything is immutable in a language you’re using, that’ll add some friction to productivity. If you’ve only ever used GC languages, manually managing memory will add some friction to productivity. Etc.
