I’d say this is pretty dependent on the language. For example, with C++, you need to micromanage (or at least benefit from micromanaging) a lot of things that you can get away without knowing about at all with other languages. That stuff takes time to pick up if you’re self-teaching as you can write stuff that looks like it works without knowing its half as fast as it could be because you aren’t making use of move semantics, and if a colleague is teaching you, then that’s time they’re not spending directly doing their own work. On the other hand, someone with Typescript experience could write pretty decent Javascript from the get-go.
C++ is unique in that it is wildly dominant in its niche. I am sure that any developer who has worked with another object oriented, manually memory managed, systems programming language (are there any other popular ones out there?) should have no trouble picking up C++.
