As a person who has written Rust code professionally for 4, here's why I returned to python: batteries included.

That's it. Having cargo download 1000s of package from who knows who for basic functionality is unacceptable. Rust's features, while absolutely phenomenal to work with, just aren't worth having insane npm-style dependency graphs and all the risks they entail. In comparison, Python's built-in modules are a godsend.

So all in all, I think you should continue to stick with python.
