@tef Taking the analogy further, I think interpreted or JIT-compiled languages (Python, JVM languages, .NET, etc.) are kind of like black-box material. Yet we build our whole applications out of them. Maybe that's one reason why our computers don't fly (in the figurative sense of being really fast) as we think they should. That's why, in principle, I like the idea of developing a whole application in Rust, though I haven't yet done it.
