Then same logic applies for python, java too? What if there is bug in internal implementation?

Rust Lang strives for safety and safety is no 1 priority. Regarding the unsafe in std please read the source code just to know how much careful they are with the implementation. They only use unsafe for performance and even with unsafe rust, it doesn't provide too much freedom tbh.

The 3rd party thing you are referring etc sounds childish. They are not the rust lang fault tbh. If you don't trust them don't use. It is as simple as that.

So I think telling people rust program that doesn't have unsafe will not have memory safety bugs. Exceptions to this statement do occurs but are rare.
