I'm not sure it's skill, more likely languages + runtime support. When I program C#, I use streaming quite a lot, often combined with async-await for I/O. The framework also helps, e.g. all compression/encryption algorithms support asynchronous versions. When I program C++, I tend to avoid streaming at all cost. The ergonomic is just not there. Technically doable, but will turn the code into callback hell, hard to debug and expensive to support.
