> Rust has automatic memory management

Sure, if you define "automatic memory management" in a bespoke way.

> Could you be more specific?

The lifetime system, one of the most complex and challenging parts of the Rust programming model, exists only so that Rust can combine manual memory management with memory safety. Relax the requirement to manage memory manually and you can safely delete lifetimes and end up with a much simpler language.
