I’ll be covering more about why Rust specifically in the talk; there are some really nifty things in its compiler and type system which allow for more than languages like Scala and Java 8. I’ve mentioned some of them in some of the other comments here; given the interest shown here, I think I’ll say more about what I hope for in the long term in a few weeks’ time. Oh, It also gives you a lot in the way of correctness which languages like Scala and Java 8 don’t give you.
