Rust absolutely does not have the ergonomics of any of those languages because it has lifetimes. They are things you don't worry about in those languages.

Have you done a lot of Rust? I spent considerable time in Rust, and at the end of the day, after stepping away from it, I've found multiple options with the kind of ergonomics that make development a lot more productive for me.

Rust is not going to eat everything. I'd bet money on it. Rust will likely un quietly behind the scenes powering lots of great projects, but its audience is limited. I think HN really has a weak spot for understanding how few people even know what it is. I was surprised to ask a CS grad student that's done lots of machine learning about Rust, and he simply didn't know it existed. I like Rust and all that it taught me, but we need to be realistic about its ceiling and what it is appropriate for.

You have to worry about them in any non-garbage collected language. There's just no compiler that checks that you're doing it correctly and is the primary source of security bugs for most software.

Understood. To be specific, they said Rust has the ergonomics of Python, Go, and Java, which are garbage collected languages. It does not strike me as realistic.
