Comparison with python actually helps to put Rust in a positive light. Compared to the Python 2/3 debacle, Rust managed to introduce a major new version with lots of new language features (edition) while making it: a) entirely opt-in, b) easy to update to with automated tooling, and c) compatible with previous versions. Compare this to Python 3, which cannot load Python 2 libraries, cannot be converted automatically, and is now effectively required with the sunsetting of Python 2 in January of this year. Python has a lot of strengths, and I think 3 is way better than 2, but the transition was very painful. Meanwhile, I have a crate I wrote a while back for 2015 nightly, and it took me less than an hour to get it up and running for 2018 stable. But I didn’t have to! Everyone using 2018 (nightly) could still use the crate even if I hadn’t converted it.
