It's not hard to understand. It's just not rational to anyone who actually calculates how performant it is (very fast, I agree) with how long it takes to write.

Once I realized how difficult it is to write complex code that actually satisfies the borrow checker, I was perfectly happy with writing somewhat slower code in Go or Python.

Anyone that has written enough systems software in various kinds of languages, using Rust isn't that bad, only when coming from scripting languages.

Anyway, I clarified on a sibling comment the reasoning behind my question.
