People bang on about borrow checking etc but really it's move semantics that's the million dollar idea in Rust - it just obliterates a huge Gordian knot of complexity in one stroke

In Rust you cannot write a move constructor. That proves limiting. But Rust move construction, also, cannot fail, which is liberating.
Rust cannot abandon backward compatibility with itself, so will increasingly be stuck with old choices, like C++, and will soon be fully as complex and infuriating. But it will, like C++, remain usually more useful than alternatives.
