You missed the point.
> In any language, if you don't use a thread safe container and mutate it from multiple threads you'll get problems.
Yes I agree there will be problems but what kind of problems do you get? Can you potentially get a memory safety problem, or are you guaranteed that the problem is not a memory safety problem?
The point is that thread safety problems in Go lead to memory safety problems. That's not the case in Java. You can crash the whole Go program by doing that, but you cannot crash the JVM by doing the same thing.
Crashing the whole program is actually memory safety. Because then the program can't get into an undefined state where parts of the program have access to memory they shouldn't.
