I think you missed the bit where he said "more intelligent compiler". The compiler is the bit that does the bookkeeping, only in Rust (and evidently Swift--I haven't played with it much) it's done statically, ahead of time rather than at runtime. That said, I think Go is a much more practical language than Rust for most problems. That said, I'm still very excited about Rust.

Yeah, that's exactly what I was trying to say. Rust does all the bookkeeping at compile time, Swift keeps a lot of it at run-time although the compiler can easily optimize away a lot of lifecycle stuff too when it's in scope, so I assume it either does or will. I agree that Rust likely does not have the be-all answer to automatic memory management, though what I love about it is that they're pushing the boundaries and getting people thinking differently about memory management.

Me too. I intend to use it for more of my hobby things, but Go is currently the best fit. Eventually I imagine Rust will pick up some decent GUI libraries or at least get decent editor support (vim-go is lightyears ahead of YCM+racer) and I'll be able to afford to justify using it more.

  These are different things. A sufficiently smart compiler is a hypothetical compiler that could theoretically optimize a high level language so that it could be faster than some low level language. This isn't what we're talking about here--we're talking about the concrete ability of the Rust compiler to preclude certain classes of errors.
