> 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.

This is consistent with my experience. Semantic versioning is very very widely used in the Rust ecosystem, so you're not looking at breaking changes unless you select a different major version (or different minor version, for 0.x crates) - which you have to do manually, cargo will only automatically update dependencies to versions which semver specifies should be compatible.

For crates that don't follow semver (which I'm fairly certain I've encountered zero times) you can pin a specific exact version.
