There aren't many pairs of mainstream languages that really interoperate well together. C and C++ do, which can blur the lines a bit. Not sure if this is what the author meant.
With rust growing in popularity and good interoperability, I suspect we'll see the rise of projects written in C/Rust and C++/Rust, and maybe even C/C++/Rust. The line will obviously be more clear because of dramatically different syntax, packaging, build system, etc.
