Programming

Yeah, that is why I prefixed that whole comment with "arguably".

I feel like the definition of memory safety is currently evolving, because I do think data races should be considered a memory safety issue.
You've got a portion of memory and access to it can be done wrongly, if the programmer isn't careful. That's what memory safety is supposed to prevent.

Rust prevents that by blocking you from passing a pointer for the same section of memory into different threads, unless you use a mutex or similar.
And because Rust sets a new safety standard, I feel like we'll not refer to Java and such as "memory-safe" in twenty years, much like you wouldn't call a car from the 90s particularly safe, even though it was at the time.
