I'm quite bullish on Rust. But note that it generally takes a while to find the "bad" parts of a technology, as they often are unintended consequences of "good"

I'm quite bullish on Rust. But note that it generally takes a while to find the "bad" parts of a technology, as they often are unintended consequences of "good" parts (which are clear and designed up front). So much that I'd consider it a sign of a mature technology when the bad parts are well-understood.
