Honestly: just ignore them. Just start using Rust! It's a lovely, useful language. HN/reddit are not representative most of the people out there in the real world writing Rust code that solves problems. I am not saying their concerns are invalid, but there is a tendency on these forums to form a self-reinforcing collective opinion that is overfit to the type of people who like to spend time on these forums. Reality is almost always richer and more complicated.
