The issue is not always garbage collection. The issue is, as others have pointed out, not having to think about it (memory & cycles.) But this also ties very much into another thing about many modern applications: excessive reliance on third-party packages, many of which are written with (or without) constraints and features that aren't always a match for the core application. It's very easy to blow out your memory use and runtime costs this way. And in this respect Rust could be vulnerable, because Cargo.toml makes it way-easy to pull in a huge tree of transitive third party dependencies without even thinking about it.
