You can segfault in Rust, too - there's a whole subset of the language marked "unsafe" that people ignore when making "safe language" arguments. The question is how difficult is it to have a segfault, and in Go it's honestly pretty hard. It's arguably harder in Rust but it's not impossible.

It's impossible in safe Rust (modulo compiler bugs and things like using a debugger to poke in the program's memory from the outside). That's the key difference.

Of course unsafe Rust is not memory safe. That's why it is called like that. :) Go has unsafe operations too (https://go.dev/ref/spec#Package_unsafe), and of course if you use those all bets are off. But as you will notice, my example doesn't use those operations.
