Exactly, if garbage collection meant memory safety then why do we get null pointer exceptions about every 5 minutes in Java. Garbage collection is about memory leaks, not safety. Imho the borrow checker is a better solution than garbage collection and faster to boot.
Null safety and memory safety are different features.
Null safety means that you cannot access a struct's fields without first checking if the pointer to that struct isn't null. And this must be a compile-time check.
Memory safety means that you cannot read or write to/from memory that has been free-ed. Without leaks ofc, otherwise it would be very easy.
A null pointer exception is technically memory safe, you can get equivalent behavior with .unwrap() on an Option in Rust.
