My point is that I can hack things up quickly and in the process discover lots of stuff without needing to be able to run the hacked together code, because typechecking it is enough to guide me in how to reshape it.
In dynamic languages you can also hack things together and run them (manually or through tests) to see how your hacks aren't fitting together right. I'm not saying untyped languages are bad, I'm saying that they are not inherently better for prototyping in my experience.
Libraries are important, but totally outside the scope of this conversation and I think its rude of you to raise an implication about them here. Everyone knows Rust is a young language and has the libraries that come with that.
