But Rust doesn't prevent bugs - it prevents safety bugs.

Your code can still generate the wrong answer.

And interpreted languages simply don't have the safety issues that Rust, C and C++ have.

Given we have finite time to develop, it would be better to develop in a language where the developers are 2-4 times more productive, and then spend some of the huge amount of time liberated to write broad and deep unit and integration tests, which you will have to do anyway in Rust.
