See below; I think I agree with what I meant by it, and disagree with what
you seem to interpret it as.  Your interpretation makes as much sense as mine,
so far as I can tell.

I suspect, thinking about it more, that it's a communications problem.

True, although it does make it a thing which *has* at least one problem.

I wouldn't.

Lemme give a concrete example, from C, since that's the language I know best.
There are sound technical reasons for which C lets you manipulate pointers.
If you couldn't, it wouldn't be C, and you couldn't do the bulk of the stuff
that makes C useful.  But...

Pointer manipulation leads to crashes.  LOTS of crashes.  I have never met
a C programmer with over a day or two of experience who has not had a
program crash due to some mishap involving a pointer.

When people say that a language like, say, Java, is trying to solve the
problems of C's pointer system, I think that's a reasonable thing to try to
do.  There are tradeoffs.  But it would be, IMHO, silly to claim that there
are no problems with pointers; there are just benefits which outweigh them
*for the things the language is trying to do*.
