Everyone better start learning Rust.
Rust programs can definitely still consume a lot of memory. Not using a garbage collector certainly helps with memory usage, but it's not going to change it from gigabytes to kilobytes. That requires completely rethinking how things are done.
That said I'm very much in favour of everyone learning Rust, as it's a great language - but for other reasons than memory usage :)
True, but memory will be freed in a more timely manner and memory leaks probably won’t happen.
.clone() everything!
I do kind of agree in a way though. Rust forces you to think a bit about memory and the language does tend to guide towards good design. But it's not magic and it's easy to write inefficient Rust too. Especially if you just clone everything. But I personally find Rust to be a good mix of low level control that feels sufficiently high level.
Garbage collected languages can be memory efficient too though. Having easily shared references is great!
After you’ve cloned everything you’ll
Arc<Mutex<>>everything.
