I've read a lot of criticism of Rust and most of it is from people who tried it for a weekend, couldn't understand the borrow checker and wrote some low quality criticism of it. If someone points out problems in that post, they are accused of zealotry and fanboyism.
Read the post I linked. It covers all the issues and makes the strongest possible case against the language. Then tell me if you've ever seen one that is as negative, accurate and succinct as that one.
