> and even modern languages like rust (stuff is always broken, or I have some incompatible version, even when it builds it doesn't work)

Been working on and off with Rust for the last 3 years, never happened to me once -- with the exception of the Tokio async runtime that has breaking changes between versions. Everything else always worked on the first try (checked with tests, too).

Comparing Python with C++ doesn't make do argument any favours, and neither does stretching a single Rust accident to mean the ecosystem is bad.
