If you can live with the wasted memory use of objects outliving their conceptual lifetime, garbage collectors can be a good solution too.
Not that that's a bad thing for many use cases, but your above comment implies a comparison between Rust and GC. I think the quoted critique falls down a bit when Rust lets you opt-in to generational-esque GC-ish behavior with a very similar downside to what you'd get from a GC.
