I've written my own programming language. IMO, "good architecture" exists outside of specific language choices - SOLID, various design patterns, etc.. I've always felt like I'm implementing the same high level design in any language I've worked with, it's just manifested and looked different, depending on the language tooling. The "good" opinions are baked into the _structure_ of the language itself, so the robots have no choice but to build well designed codebases.
