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.
