I agree that fast iteration time is valuable, but I don't think this has to hold 100% of the time.

I would much rather bang my head against a compiler for N hours, and then finally have something that compiles -- and thus am fairly confident works properly -- than have something that compiles and runs immediately, but then later I find I have to spend N hours (or, more likely, >N hours) debugging.

Your preferences may differ on this, and that's fine. But in the medium to long term, I find myself much more productive in a language like Rust than, say, Python.
