Rust does memory-safety in the most manual way possible, by requiring the programmer prove to the compiler that the code is memory-safe. This allows memory-safety with no runtime overhead, but makes the language comparatively difficult to learn and use.
Garbage-collected compiled languages — including Java, Go, Kotlin, Haskell, or Common Lisp — can provide memory-safety while putting the extra work on the runtime rather than on the programmer. This can impose a small performance penalty but typically makes for a language that's much easier on the programmer.
And, of course, in many cases the raw performance of a native-code compiled language is not necessary, and a bytecode interpreter like Python is just fine.
The most manual way is what C does, which is requiring the programmer to check memory safety by themselves.😛
Also will say that outside of some corner cases, Rust is really not that harder than Java or Python. Even in the relatively rare cases that you run into lifetimes, you can usually clone your data (not ideal for performance usually but hey its what the GC language would often do anyway). And reliability is far better in Rust as well so you save a lot of time debugging. Compiles = it works most of the time.
