Why do we need different systems for all languages, all Linux/Windows/Mac/Android distributions. Why are no one reusing what is already there. It might seem like an easy problem to fix. Rust, Java and Go certainly has their problems too, not quite sure why people feel they are good examples. I think the world is complicated and you will in the end need to support compilations/installations on AmigaOS 2.05 on m68k running in kubernetes native.
