I see a very big gap between "memory issues" and "memory management issues" ... for me the first thing is "thinking about memory, how much you will use, etc.", the second is "Okay, I've allocated a string here. Who the heck will be the one that cleans it up?" - high level languages fix the second case (if you LIKE the fix, that's a different topic, but it is a fix), they don't (and cannot and never were claimed to) fix the first case, because that would need an AI like runtime environment. (Okay, your quote [4] is actually talking about both, so .. one of four examples fits?)
