>I don't agree with the article either, one could make the same argument for every piece of new code written. No you can't. The issue is that languages generally have their own runtime and object linkage system. If you create a new one that doesn't play nicely with C linkage/runtime, JVM, .Net, or compiles down to javascript (or wasm) then you are creating an entirely new platform and this creates the fragmentation. For example, Python and Rust play nicely with C linkage. Scala runs on the JVM. These play nicely with other systems. You can have Python code that calls Rust code that calls C code and it all fits together. But you may struggle to have Python code calling Lua code calling Julia code. "every piece of code written" doesn't have this problem at all. If you write something in an existing language then you are contributing to that ecosystem instead of making a new ecosystem. And if you are making a new ecosystem, for pity's sake please consider making that ecosystem play nicely with at least one existing ecosystem.
