> Yes, Julia is faster than R and Python (just the language, not packages), but R and Python can easily integrate with C/C++ and many R and Python packages are in fact internally C/C++. This is what I was responding to. The grandparent argued that Julia had less library support than R and Python because, so they implied, those languages could interop with C/C++ in a way Julia can't. The two language problem refers to code in user space, anyway. It's not like Rust, where there are so many wheel-reinventing projects in progress. If you peruse the main Julia package registry, and you'll see plenty of library-wrapping modules.
