Rust doesn't eliminate all bugs. But anecdotally, by the time the type checker and borrow checker have humbled me, my programs really do often work the first time I run them. Its quite remarkable.

This isn't a special thing about rust. All languages are on a spectrum of "detect all bugs statically" to "detect all bugs dynamically". Rust programs run correctly "first time" more than javascript, more than typescript. But still less than haskell.

You can still write bugs in rust, obviously. I've written plenty. As you say, so has cloudflare. But strong typing does find a lot of bugs in practice.
