It depends on the domain. Sometimes a wrong answer is worse than a crash (e.g. a bank). Sometimes it is better (e.g. a game).

Similarly the worst bugs can be crashes (random, non-deterministic, release-mode only, timing sensitive heisenbugs), or they can be undetected algorithmic errors.

It entirely depends on the specifics. But either way, Rust's tradeoffs are easily worth it in terms of eliminating bugs unless you really don't care.

The domain is "sending a rocket to space" whose specifics are, in general, not only that you really don't care, but that one of the things you want to maximise and make as easy as possible is inspectability by humans.
