You're quite right, thank you, upvoted.

However if he says "Rust gets us 80% of the way there" as you point out then he is obliged, IMO, to point out explicitly the 20% where it fails or we can't even begin to discuss it.

He mentions Rc and Arc which I assume is what he means by the 20%. I tend to agree, although I'm not sure how you would get rid of them.
